Are the chemicals used to Decaffeinate coffee harmful?
If your coffee is labeled naturally decaffeinated or Swiss water processed, you can be assured that no harmful chemicals are used. A direct decaffeination process involves the use of carbon dioxide as a solvent. The coffee beans are soaked in compressed CO2, which removes 97 percent of the caffeine.
Is formaldehyde used to Decaffeinate coffee?
Decades ago, there were thoughts that coffee was decaffeinated using formaldehyde. While this myth is completely not true, many people do not really know how coffee is decaffeinated.
Is there a naturally decaffeinated coffee?
Researchers have discovered a naturally decaffeinated variety of the popular arabica coffee bean that may be able to pass on its low-caffeine trait to other arabica coffee bean plants through breeding.
What chemicals are in decaffeinated coffee?
There are several ways to decaffeinate coffee but the most prevalent is to soak them in a solvent – usually methylene chloride or ethyl acetate. Methylene chloride can be used as a paint stripper and a degreaser as well an agent to remove caffeine.
What process does Starbucks use to decaffeinate coffee?
Starbucks, which uses methyl chloride to decaffeinate most of its blends, now offers a “naturally processed” decaf Sumatra brew. Caribou Coffee uses a non-chemical water process in all its decaf blends.
How does Dunkin Donuts decaffeinate their coffee?
Many coffee manufacturers still use chemicals like methylene chloride – commonly used in paint removers – to strip away caffeine. uses chemicals or carbon dioxide.
How does Peet’s decaffeinate their coffee?
All Peet’s beans and K-Cup® pods are decaffeinated by water process.
Where is decaffeinated coffee made?
Generally, decaffeination involves water-logging coffee beans when they’re still green (before roasting) so that the caffeine inside can be made soluble, meaning that it can be dissolved. But there are different ways of washing that caffeine out of the beans.
What is the best way to decaffeinate coffee?
The most-common methods of decaffeination involve chemical solvents, usually ethyl acetate or methylene chloride. In the direct method, the coffee beans are steamed and then rinsed repeatedly with the chemical solvent to flush away the caffeine.
How do you Decaffeinate yourself?
What you can do to feel better
- No more caffeine. Don’t consume any more caffeine today.
- Drink plenty of water. Caffeine is a diuretic, which means that you need to drink extra water to make up for what you’re peeing out.
- Replace electrolytes.
- Take a walk.
- Practice deep breathing.
How do you naturally Decaffeinate coffee?
Ethyl acetate is an ester that is found naturally in fruits and vegetables such as bananas, apples and coffee. The liquid solvent is circulated through a bed of moist, green coffee beans, removing some of the caffeine; the solvent is then recaptured in an evaporator, and the beans are washed with water.
Does decaf coffee make you poop?
While caffeine is a great energy booster, it may also stimulate the urge to poop. Research has shown that caffeine makes the colon 60% more active than water and 23% more active than decaf coffee ( 6 ). However, studies have shown that decaf coffee can also stimulate the urge to poop.
What is the healthiest decaffeinated coffee?
The Swiss Water decaf is a chemical-free decaf coffee that retains most of coffee’s precious flavor and potent antioxidants, making it the healthiest decaffeinated coffee on the market. The lack of chemicals compared to the other popular methods also makes it a more earth-friendly option.
How does Green Mountain decaffeinate their coffee?
The “direct process” decaffeination uses a variety of FDA approved solvents, other than just water. These solvents are normally methylene chloride or ethyl acetate. The caffeine is bonded to the solvents and extracted from the coffee after it has been steam heated. And the coffee comes from Green Mountain Coffee.
Is decaf coffee really decaf?
What Is Decaf Coffee? Decaf coffee is not completely caffeine-free. While USDA regulations stipulate that decaf should not exceed 0.10 percent caffeine on a dry basis in the package, comparison between brewed regular and decaf coffee shows that decaf appears to have at least 97% of caffeine removed (3, 4, 5 ).
How do you decaffeinate coffee?
What is the best way to decaffeinate coffee? (Image courtesy of Getty Images) ) Some of us enjoy the flavor of coffee but are unable to tolerate the side effects of caffeine. So, what is the best method for extracting caffeine from a coffee bean? If you enjoy a cup of coffee without the caffeine, you should remember Friedlieb Ferdinand Runge the next time you boil the kettle and lift your mug in his honor. It was Goethe who first became aware of Runge’s work as a 19th-Century German chemist. Goethe was both a poet and a statesman, and he was also a serious scientific scholar.
Runge had discovered and isolated the substance that, when consumed, caused ocular muscles to dilate and constrict.
What Runge found is caffeine, which is undoubtedly the most widely taken substance in the modern world.
- The health advantages of coffee that are not widely known
- The sickness that has the potential to alter our coffee drinking habits
- What amount of coffee should you consume
Caffeine may be found in a variety of different beverages and foods, most notably tea and chocolate, although it is most closely associated with coffee. For students studying for exams, nightshift employees and anybody else who has to get out of bed in the morning, it’s an excellent stimulant and appetite suppressant that they can rely on. Caffeine, on the other hand, has a negative side effect. Anxiety, sleeplessness, diarrhea, excessive perspiration, a racing pulse, and muscular tremors are all possible side effects.
- As people’s appreciation for coffee has risen, the flavor of decaffeinated coffee has improved as well.
- Any grocery aisle will tell you that the answer is yes – but the procedure is not as straightforward as you may assume it to be.
- He was another German who made the discovery.
- After being flooded by saltwater while in route in 1903, a shipment of coffee was discovered to have lost its caffeine but not its flavor.
- The invention of decaffeinated coffee was made possible.
- In fact, according to Chris Stemman, executive director of the British Coffee Association, most of the decaffeination procedures that were developed in the early days of the industry are still in use today.
- In the words of Stemann, “it isn’t done by the coffee firms themselves.” ‘There are decaffeination firms that specialize in this process,’ says the author.
You could believe that it would be quicker to roast the coffee, grind it into the desired powder (espresso, filter or instant) and then begin the decaffeination procedure.
“It takes place while the coffee is green, before roasting.“ If you were to attempt to decaffeinate roasted coffee you’d wind up creating something that tastes a bit like straw.
Methylene chloride may be used as a paint remover and a degreaser as well an agent to eliminate caffeine.
The beans are first soaked in water and then coated in a solution containing one of these solvents.
The solvent-laced water is then reused again and again until it is packed with coffee flavourings and compounds – very much similar to the beans, except for the caffeine and solvent.
Soaking coffee beans in solvents doesn’t sound like a particularly healthy operation, yet both of these agents have acquired a clean bill of health.
(FDA standards allow up to 10 parts per million of residual methylene, while coffee decaffeination normally utilizes solutions with one part per million).
TheSwiss Water methodsees the beans soaked with water; the caffeine rich solution (full of tastes) is then squeezed via activated carbon which collects the caffeine.
It gained prominence since it was the first decaffeination process not to utilize solvents.
Beans that have been soaked in water are put in a stainless-steel extractor which is then sealed, and liquid CO2 blasted in at pressures of up to 1,000lbs per square inch.
The gas is then taken out and the pressure is decreased, leaving the caffeine in a separate chamber.
“It can be tremendously expensive.” Coffee firms don’t normally remove the caffeine themselves – it’s done by specialised companies (Photo courtesy of Getty Images) ) Decaffeination grew much more prevalent as instant coffee became a norm, adds Stemman.
“If you look back 20 or 30 years ago, wereally were a country of instant coffee drinkers,” he adds.
Decaff was far worse.” Stemman argues that as consumers have gotten more acclimated to quality coffee – for instance, the UK now has some 24,000 coffee shops – this has prompted coffee-making businesses to research ways of increasing flavour even in decaffeinated instant coffee.
In the UK at least, the number of individuals stumping for a decaff coffee has declined considerably even as the quality has increased — although as many as 15 percent of coffee consumers preferred decaffeinated drinks in the 1980s, that’s plummeted to roughly 8 percent now.
“Generally, no, if I don’t want the caffeine, well I just won’t have a coffee or a tea.” And there’s another thing.
If you truly want to avoid any caffeine at all, it’s usually best to consume something that never had a trace of it in the first place.

Decaffeination 101: Four Ways to Decaffeinate Coffee
Let’s start by expressing the blatantly obvious. Because caffeine naturally appears in coffee, many coffee connoisseurs regard any method of decaffeination (no matter how effective) to be unnatural. According to some, it is even against the natural order of things. However, there are around 10% of coffee drinkers who would like to enjoy a decent cup of coffee without the stimulant impact of caffeine in their beverage. PS: I’ve created another post that discusses alternative techniques of reducing caffeine use.
Is it possible to drink a GOODcup of coffee after it has been exposed to a decaffeination procedure?
WARNING: EMPTOR’S CAVEAT: The term “decaffeinated” does not always imply that the beverage is completely caffeine-free.
In other words, a typical 12 oz.
What All Decaffeination Processes Have in Common
We should first look at what all decaffeination processes have in common before diving into the specifics of each one.
- Caffeine is always removed from coffee beans when they are in their green (unroasted) stage. The most difficult issue is to extract solely caffeine from coffee beans while keeping the other compounds in their original concentrations. This is difficult due to the fact that coffee includes over 1,000 compounds, all of which are vital to the flavor and scent of this beautifully complex elixir. Due to the fact that caffeine is a water-soluble chemical, water is utilized in all kinds of decaffeination
- Yet, water is not the optimum decaffeination solution on its own. In addition to caffeine, water is not a “selective” solvent, and as a result, it removes other soluble compounds such as carbohydrates and proteins as well. As a result, a decaffeinating agent is used in all decaffeination operations (such as methylene chloride, activated charcoal, CO 2, or ethyl acetate). Using these agents, you may expedite the process while reducing the “washed-out” impact that water alone would have on the taste of decaf coffee.
The Roselius Process
Ludwig Roselius, a German coffee trader, created and patented the first commercially viable decaffeination technique in 1903, which was later patented again in 1906. He was allegedly driven in his search for decaffeinated coffee by the assumption that his father had been poisoned by his father’s excessive coffee consumption, according to legend. The “Roslius Process” entailed heating coffee beans in a brine solution (i.e., water saturated with salt) and then extracting the caffeine from the beans using the organic chemical compound benzene as a solvent.
The Four Main Methods of Decaffeination Used Today
Let’s divide the four processes into two main categories, each of which has two ways, in order to keep everything neatly organized.
Those procedures in which the caffeine is extracted from the beans with the use of a chemical solvent, such as methylene chloride or ethyl acetate, are known as solvent-based processes. Those solvent-based processes may be further subdivided into those that employ the “direct” technique and those that employ the “indirect” method. Caffeine is extracted from materials using the direct approach, which involves soaking the materials in a solvent and then applying the solution directly to the beans.
Solvents used in decaffeination
As previously stated, decaffeination of coffee is accomplished by the application of a decaffeination agent. To selectively remove the caffeine in solvent-based procedures, a chemical solvent is supplied, either directly or indirectly, into the process. In light of the numerous health concerns associated with early efforts in decaffeination (the hit list of toxic solvents includes: benzene, trichloroethylene (TCE), dichloromethane, and even chloroform), the solvents of choice have evolved to include methylene chloride and ethyl acetate as alternatives.
- To the contrary, the Food and Drug Administration (FDA) has found that any possible health risks are so minimal as to be “almost non-existent” (FDA, 1985).
- It is also possible that traces of the solvent remain in the decaffeinated beans, however it is quite improbable that methylene chloride will survive the roasting process.
- Given that coffee is roasted at a minimum temperature of 400 degrees Fahrenheit for at least 15 minutes and that the optimum brewing temperature is around 200 degrees Fahrenheit, it appears that little, if any, methylene chloride will wind up in your cup of java.
- In recognition of the fact that this solvent occurs naturally in nature, it is common to see coffee beans decaffeinated using this process branded as “naturally” decaffeinated.
- Ethyl acetate is commercially generated from ethyl alcohol and acetic acid, both of which can be derived from natural components or petroleum derivatives, respectively.
Now that we’ve established a foundation upon which to build, let’s take a deeper look at the approaches that were previously stated. Because solvents are used to decaffeinate 70% of all coffee, I’ll start with solvent-based decaffeination procedures.
1) The Indirect–Solvent Based Process
For many hours, the coffee beans are steeped in almost boiling water to remove the caffeine as well as other taste components and oils from the beans. It is then filtered out and moved to another tank, where it is used to wash the beans for around 10 hours with either methylene chloride or ethyl acetate. The molecules of the chemical solvent form selective bonds with the molecules of caffeine, and the resultant mixture is heated to the point when the solvent and caffeine are completely removed from the combination.
This approach, which is very common in Europe, particularly in Germany, is based on the use of methylene chloride as a solvent.
2) The Direct–Solvent Based Process
In this process of decaffeination, the beans are steamed for around 30 minutes in order to open their pores and let the caffeine to be released. The coffee beans are repeatedly washed with either methylene chloride or ethyl acetate for approximately 10 hours to remove the caffeine after they have been exposed to a solvent for a short period of time. The solvent containing caffeine is then drained away, and the beans are steamed again to eliminate any remaining solvent from the beans. The most common solvent used in this procedure is ethyl acetate, which is why it is called to as “The Natural Decaffeination Method” or “The Ethyl Acetate Method” most of the time.
1) The Swiss Water Process (SWP)
The SWP Method, Swiss Water Process, Activated Charcoal Decaffeination, and Dihydro-oxide Process are all names for the same thing.
The water decaffeination technique, which is devoid of chemical additives, was first invented in Switzerland in 1933 and economically feasible by Coffex S.A. in 1980, after which it became widely available. When the Swiss Water Method was ultimately presented to the market in 1988, it was located in Vancouver, British Columbia, Canada, at a facility called Swiss Water Technologies. It should be noted that the Swiss Water Company’s decaffeination factory is the only one in the world to be certified organic by both the Organic Certification Institute of America (OCIA) and Aurora Certified Organic.
A Short Explanation of SWP
When compared to the methods we’ve seen so far, this specific method of decaffeination differs in that it does not use chemicals to remove the caffeine directly or indirectly from the coffee. Instead, it depends only on two ideas, namely solubility and osmosis, in order to decaffeinate the coffee beans in question. It all starts with soaking a batch of beans in extremely hot water for many hours in order to breakdown the caffeine. The water is then drained and run through an activated charcoal filter to remove any contaminants.
The result is that one tank has no caffeine and no taste, while the other tank contains caffeine-free “flavor charged” water (called “Green Coffee Extract”) that has been “flavor charged.” And it’s at this point when the magic happens.
Because this water has previously been saturated with flavor compounds, the tastes in this new batch will not be able to dissolve; only caffeine will be transferred from the coffee beans to the water at this point.
Whenever this procedure is used to decaffeinate coffee, it is designated as “SWISS WATER” Decaf.
Consistent caffeine level assessments are carried out on coffee decaffeinated using the environmentally friendly Swiss Water Process to assure compliance with the 99.9 percent caffeine-free standard.
2) CO 2process
CO 2 (or Carbon Dioxide) Method, Liquid Carbon Dioxide Method, and Supercritical Carbon Dioxide Method are all names for the same procedure. Currently, the Carbon Dioxide (CO 2) Approach is the most current method to be developed. It was invented by Kurt Zosel, a scientist at the Max Plank Institute, and it replaces chemical solvents with liquid CO 2. It has a selective action on caffeine, releasing only the alkaloid and nothing else as a result of its action. The extraction vessel, which is made of stainless steel, is used in the CO 2decaffeination process to hold the coffee beans after they have been soaked in water.
In order to dissolve and pull caffeine from the coffee beans, CO 2 works as a solvent, separating it from the larger-molecule taste components.
It is at this point that the pressure is released and the CO 2 returns to its gaseous condition, with the caffeine remaining behind.
The expense of this technique makes it most suitable for decaffeinating huge amounts of commercial-grade, less exotic coffee available in supermarkets.
Why is it so Difficult to Make Good Decaf Coffee?
Begin by acknowledging an unfortunate reality: obtaining a good decaf coffee is more of an exception than the rule these days. The reason for this is due to the existence of two difficulties that are extremely tough to resolve. First and foremost, as we’ve previously shown, the decaffeination process has a negative impact on several taste chemicals that contribute to the sensory character of roasted coffee. Second, decaf coffees are notoriously difficult to roast due to their high caffeine content.
- They respond inconsistently and exaggeratedly to the heat given to them during roasting, making it difficult for the roasters to maintain control over their temperature and roasting time.
- As a result, you’re dealing with an unroasted “green” bean, which roasts darker and more quickly than un-decaffeinated beans because of the presence of caffeine.
- What we’ve learnt so far may be applied in order to provide a better decaf experience for our customers.
- Always steer clear of really dark and oily decaf coffees; you don’t want to subject your body to the ravages of an extremely dark roast while also enduring the rigors of the decaffeination process.

All About Decaffeinated Coffee
Independent scientific research demonstrates that coffee, whether it contains caffeine or not, is connected with a variety of health advantages, including improved lifespan and a lower chance of developing several malignancies and chronic illnesses. Despite the fact that more than 90 percent of American coffee users prefer caffeinated brews, decaffeinated brews are a terrific choice for individuals who desire the flavor and social connections of drinking coffee without the adrenaline boost that comes with caffeine infusions.
How is coffee decaffeinated?
Decaf coffee, like normal coffee, starts off as green, unroasted beans that are then roasted. It is possible to remove caffeine from hard beans by heating them in liquid and soaking them in it in one of four ways: with water alone, with water and solvents (most commonly methylene chloride or ethyl acetate), with water and “supercritical carbon dioxide,” with water and “supercritical carbon dioxide,” and with water and “supercritical carbon dioxide.” All four procedures are completely safe, and once the caffeine has been removed (at least 97 percent of it), the beans are washed, steamed, and roasted at temperatures high enough to evaporate all of the liquids used in the decaffeination process.
How much caffeine is in decaf coffee?
Decaffeination is the process of removing around 97 percent or more of the caffeine from coffee beans. A normal cup of decaf coffee has around 2 mg of caffeine, but a typical cup of regular coffee contains approximately 95 mg of caffeine, according to the USDA.
Is decaf coffee bad for you?
In the same way that any coffee is safe to consume, decaffeinated coffee may be included in a healthy diet as well. If you’re wondering if the decaffeination process itself is safe, the answer is a resounding affirmative. Every one of the four procedures is safe, and once the caffeine has been extracted (at least 97 percent of it), the beans are washed, steamed, and roasted at high temperatures in order to evaporate the liquids used in decaffeination. The Food and Drug Administration of the United States has established a stringent standard to assure that even the smallest quantities of solvents used to decaffeinate coffee are not harmful.
How much caffeine is too much?
According to regulators and health authorities in the United States and throughout the world, moderate caffeine use may be a component of a healthy diet for the majority of individuals – normally up to 400mg per day, or around 4-5 cups of coffee. Individuals suffering from particular medical issues may require different guidelines. When thinking about your caffeine consumption, keep in mind that caffeine may be found in a variety of foods and beverages other than coffee, so think about all of the possible sources before making a decision.
Because every person’s body is unique, it is important to review health guidelines from reputable sources, pay attention to how your body responds to caffeine, and speak with your own physician if you have any concerns or questions.

How is caffeine removed to produce decaffeinated coffee?
Sign up for free newsletters from Scientific American. ” data-newsletterpromo article-image=” data-newsletterpromo article-button-text=”Sign Up” data-newsletterpromo article-button-link=” name=”articleBody” itemprop=”articleBody”> name=”articleBody” itemprop=”articleBody”> Professor Fergus Clydesdale of the University of Massachusetts Amherst’s Department of Food Science responds as follows: “First, some background information. The beverage coffee comes in second place behind tea in terms of popularity across the world.
- Coffee contains caffeine, which is the active ingredient responsible for the beverage’s modest stimulatory impact on the central nervous system.
- Even 10 milligrams of caffeine might produce pain in persons who are sensitive to the stimulant.
- In today’s globe, decaffeinated coffee accounts for around 12 percent of overall coffee consumption, or nearly 1 billion pounds per year.
- When it came to removing caffeine from pre-moistened green coffee beans, Roselius’ process relied on benzene, a potentially hazardous chemical.
- According to the FDA, there are three primary decaffeination procedures in use.
- Each method begins with moistening the green or roasted beans, which makes the caffeine soluble so that it may be pulled out using the extraction method chosen.
- One way is the treatment of water.
Typically, a battery extraction method with eight to twelve vessels is used; each vessel contains green coffee that has been decaffeinated to a different degree.
Upon reaching a predefined length of time after being exposed to the low-caffeine extract, the vessel is separated and emptied of its contents.
To remove the caffeine-rich extract, it is passed over a bed of activated charcoal, which absorbs the caffeine from the vessel containing the freshly brewed green coffee.
The sucrose prevents carbon sites from absorbing sugars from the liquid green-coffee extract, which would otherwise occur.
Natural (in that it does not include the use of chemicals) but not highly precise for caffeine removal, the water procedure eliminates between 94 and 96 percent of the caffeine.
Nowadays, this approach is frequently employed in conjunction with methylene chloride (which is most commonly used in Europe), coffee oil, or ethyl acetate in order to dissolve the caffeine and extract it from the coffee.
During the processing of green coffee beans, a liquid solvent is cycled through the beans, eliminating part of the caffeine.
By steaming the beans, the solvent residues are reduced to trace amounts and the coffee is safe to drink.
A common reason for the employment of solvents is because they are typically more specific in their targeting of caffeine than charcoal, leaving behind virtually no noncaffeine substances.
The third technique, supercritical carbon dioxide decaffeination, is essentially similar to the direct solvent procedures, with the exception that the solvent in this case is carbon dioxide instead of a solvent.
When subjected to such high pressures, carbon dioxide acquires unique’supercritical’ characteristics that improve its suitability as a solvent.
Its pumping expenses are greatly reduced as a result of these characteristics.
The caffeine-rich carbon dioxide that exits the extraction vessel is either directed through a bed of activated charcoal or through a water ‘bath’ tower in order to absorb the caffeine present in the gaseous state.
Even though supercritical carbon dioxide decaffeination is a capital-intensive process, it generates extremely high yields. It can often extract 96 to 98 percent of the caffeine that was initially present in the beans,” says the manufacturer.
How Chemical Free Decaf is Made
In many plant species, caffeine is present in the leaves, seeds, and fruit. It can be found in coffee beans, green tea leaves, and cacao seeds, among other things. Caffeine is a naturally occurring stimulant that can be found in many plant species. It’s likely that you’re among the approximately 83 percent of adults in the United States who enjoy starting the day with a warm cup of coffee, but you want to reduce your daily caffeine intake for various reasons such as personal preference, sensitivity, or pregnancy.
This tutorial will assist you in understanding what caffeine is and the many ways used to remove it from coffee, including theSwiss Water procedure we use to manufacture all-decaffeinated Kauai Coffee, which you can learn more about here.

Decaf Coffee 101: What’s the Buzz?
For a better understanding of how caffeine is removed from coffee, it is necessary to have a basic understanding of its molecular structure. Caffeine is an alkaloid that occurs naturally in plants and is used to stimulate the central nervous system. An alkaloid is a naturally occurring chemical substance that contains at least one nitrogen atom and that has physiological effects on humans and other living things. When consumed by humans, caffeine can operate as a stimulant; yet, it can also act as a plant’s natural defense against insects and other animals.
The quantity of caffeine contained in a single serving of coffee varies depending on the type of bean used and how it is prepared.
It’s also vital to understand that decaf coffee does not necessarily indicate that it’s caffeine-free.
Friedlieb Runge is a German author and poet.
Decaf Coffee History
Due to his work in 1820, German chemist Friedlieb F. Runge is generally referred to as the “godfather of caffeine” since he was the first scientist to successfully separate caffeine from coffee. German coffee salesman Ludwig Roselius invented the first commercial decaffeination technique in 1906, which required heating green coffee beans with water and different acids, followed by the use of Benzene as a solvent to dissolve the caffeine. Roselius’ invention was the first of its kind. Benzene, an organic chemical component, is no longer used in Roselius’s approach since it has been identified as a carcinogen by the American Cancer Society, which replaced Roselius’s method.
How Decaf Coffee is Made
While the coffee beans are still green, the caffeine is extracted from them. In contrast to roasted coffee beans, green coffee beans are beans that have been collected and taken from the fruit, but have not yet been roasted. When green coffee beans are suitable for decaffeination, there are a number of different processes for eliminating caffeine that are currently in use.
When it comes to caffeine removal, solvent-based procedures rely on chemicals such as ethyl acetate or methylene chloride, but the Swiss Water® approach uses just water, time, and temperature.
Solvent-based decaffeination makes use of ethyl acetate (found in ripening fruit and alcohol) or Methylene chloride solvents that are applied directly or indirectly to green coffee beans in order to dissolve the naturally occurring caffeine present in the coffee beans. Although the United States Food and Drug Administration has found that none of these solvents is harmful to human health, some coffee enthusiasts believe that coffee decaffeinated using a solvent-based approach has less taste and depth than coffee decaffeinated using other methods.
The Swiss Water® Decaf Process – No Added Chemical Solvents
Solvent-based decaffeination makes use of ethyl acetate (found in ripening fruit and alcohol) or Methylene chloride solvents that are applied directly or indirectly to green coffee beans in order to dissolve the naturally occurring caffeine present in the beans. However, although the United States Food and Drug Administration has ruled that none of these solvents constitutes a health concern, some coffee enthusiasts believe that coffee decaffeinated using a solvent-based approach has less taste and depth than coffee decaffeinated using other methods.
How Swiss Water® Process Decaffeination Works
Briefly stated, the Swiss Water Process depends on caffeine solubility (dissolvability) and osmosis to remove caffeine from green coffee beans during the extraction process. Decaffeination begins with the soaking of green coffee beans in hot water for a short period of time to dissolve the caffeine. It is important to note that caffeine is not the sole water-soluble chemical found in coffee. When it comes to coffee, sugars and other chemical components that contribute to the flavor and fragrances that we enjoy can dissolve in water.
The water from the first round of green beans is filtered through a charcoal filter after it has been soaked for many hours.
This water, which has been infused with green coffee extract, is now being used to soak the next batch of green beans.
Although it appears to be a difficult process, the end result is decaffeinated coffee that is rich in taste and devoid of any added chemical solvents.

How Is Decaf Coffee Made?
Green and brown decaf unroasted and black roasted coffee beans are displayed in a wooden box. (Image credit: Shutterstock)The history of decaf coffee begins, rather unexpectedly, with Johann Wolfgang von Goethe.Goethe, who wrote the tragedy “Faust,” was one of Germany’s most famous authors, but he was also a natural scientist who studied plants and animals. When Goethe visited the chemist Friedlieb Ferdinand Runge in 1819, he witnessed him show how lethal nightshade extract could enlarge the pupils of a cat.
A couple of years later, Runge became the first scientist to isolate and identify caffeine in its purest form.
(Those who are extra-sensitive to the jittery effects of a cup of strong coffee probably won’t be surprised to learn that the discoverer of the stimulant had a penchant for working with deadly substances; his colleagues and students allegedly nicknamed him “Doktor Gift,” which translates as “Dr.

Today, decaffeination is a time-consuming procedure that is carried out in specialist facilities, as described above. In an interview with Live Science, David Kastle, a senior vice president at the Canada-based company Swiss Water Decaffeinated Coffee, said that while “there are a couplevery largecompanies that own their own decaf plants,” “every other company either contracts directly with a decaffeination company or they contract through an importer.” Generally speaking, decaffeination is accomplished by water-logging coffee beans while they are still green (i.e., before roasting) in order to make the caffeine within soluble, which means that it may be dissolved.
- However, there are a variety of methods for removing the caffeine from coffee beans.
- In one piece of mythology concerning the origins of decaf, according to Atlas Obscura, it is claimed that Roselius received a cargo of coffee beans that had been steeped in seawater.
- He discovered that the coffee had been decaffeinated, but that it still essentially tasted like coffee, although with a slight salty aftertaste (see photo).
- His firm, Kaffee HAG, was the first to commercially make instant decaf coffee in the United States.
(As shown in the 1982 film “In “Fast Times at Ridgemont High,” a biology instructor begs his pupils to understand that “I’m running a bit behind today.” Have pity on me because I’ve just switched to Sanka “) ) ) ) ) ) ) ) Because it is a proven carcinogen, benzene is no longer utilized in the decaffeination process for coffee.
- The Food and Drug Administration (FDA) has determined that minute trace levels of methylene chloride in decaf coffee are not harmful and that residues more than 0.001 percent are forbidden.
- Kurt Zosel, a chemist at the Max Planck Institute for Coal Research in Ruhr, was involved in research with supercritical carbon dioxide.
- In 1970, the scientist received a patent for his decaffeination procedure, which is still commonly used today.
- Another approach, named the Swiss Water Process, was initially commercially used in the 1970s and is still in use today.
- After that water gets saturated with all of the soluble components contained in coffee — including chlorogenic acid, amino acids, and sucrose — it is filtered to remove the caffeine using charcoal.
- In order for the beans and liquid to achieve equilibrium, Kastle explained that caffeine migrates from the beans to the green coffee extract until the beans are nearly totally devoid of caffeine.
- Some coffee firms, on the other hand, do publicize their production practices.
However, this is still far lower than the caffeine content of a caffeinated cup of joe; for reference, the same amount of ordinary coffee typically contains between 80 and 100 mg of caffeine.

Why isn’t decaf cool yet?
In my opinion, decaffeinated coffee is like a hooker that is solely interested in cuddling.” This quotation, like many others on Instagram, is designed in a cutesy sans serif font and has the beigeness of a black-and-white photograph that has been shared and refiltered hundreds of times. The hashtags CaffeineAddict, WorkingMomLife, and the clincher, DeathBeforeDecaf, are all found beneath it. A more offensive end of a spectrum made up of hundreds of coffee-related quotations on Instagram that indicate the poster would rather practically die than consume a morning beverage that doesn’t include caffeine is represented by this quote.
- Coffee memes for parents, coffee memes for CrossFitters, coffee memes for entrepreneurs, and even coffee memes for multilevel marketers are all available.
- And it does, to some extent – according to the National Coffee Association, 64 percent of Americans drink coffee every day, and 87 percent frequently ingest caffeine.
- Perhaps this is correct.
- Caffeine, on the other hand, remains a drug, albeit an addicted one, and these are frightening words.
- So, where has the caffeine retaliation gone?
- The entrepreneurs rushing to offer the next fashionable decaf coffee brand are nowhere to be found.
- Caffeine addiction is something many people struggle with on a regular basis.
- The United States has been significantly more tolerant to those with a wide range of food sensitivities and dietary restrictions in the last decade or two.
- Despite the fact that sales of dairy-free milk increased by 61% between 2012 and 2018, the industry is now worth $2 billion (there was even a much-fussed-overoat milk shortage in the summer of 2018).
- Even chain restaurants are embracing restrictive diets: Chipotle recently began offering special bowls for adherents of keto, Paleo, and Whole30 diets, the last of which is so militant that it bans all forms of dairy, grains, sugar, alcohol, and legumes — but not coffee.
- It can still be difficult to find a decaf option in coffee shops that aren’t one of the major chains, and caffeine labeling on productsremains largely unregulated and incoherent.
Caffeine has all the elements required to spark a backlash in the year 2019: Thevast majority of us regularly drink it, which is why removing it from one’s diet can demonstrate a monk-like ability to refuse indulgences (which is pretty much what all of wellness culture is based around) (which is pretty much what all of wellness culture is based around).
- Sure, for most, cutting caffeine alone won’t change one’s overall life or health that much, butneither will most diets.
- Though caffeine isn’t great for people on the anxious end of the spectrum, for tired folks or those who fall more on the depressive side, the effects can be positive.
- (Theexecutive producer later said it was originally supposed to be speed, which would have made a lot more sense.) Whether caffeine is or isn’t actually good for you isn’t actually the point.
- There isn’t.
- I was one of them once, before a hastily guzzled single Starbucks Doubleshot Espresso preceded my first panic attack, an anxiety disorder, and an inability to drink caffeine without experiencing terrifying heart palpitations that lasts to this day.
- But it was the latter whose life-altering effects were the most surprising: In the span of a few minutes, coffee went from the joyous, hot thing that got me through the days to a poison that everybody else was immune to.DeathBeforeDecaf, however, is not really about a love of coffee.
- They’remaking Mondays their bitch.
There are now multiple names for it: Depending on how you feel, it’s either hustle culture or it’s “ millennial burnout ” or “ workism.” In arecent New York Times piece, writer Erin Griffith described performative hustling as “obsessed with striving, relentlessly positive, devoid of humor, and — once you notice it — impossible to escape.” The Atlantic’s Derek Thompson writesthat social media has amplified the pressure to craft a successful image, and because a growing number of white-collar jobs produce invisible results (as opposed, to, say, construction), “today’s workers turn to social media to make manifest their accomplishments.
- Many of them spend hours crafting a separate reality of stress-free smiles, postcard vistas, and Edison-lightbulbed working spaces.” Also often present in such Instagram posts: coffee.
- It’s less to do with the actual drink than the drug: It’s the caffeine that givesmommy her go-go juice, not the coffee.
- If decaf is for old folks at diners — a reputation that has some cause; many seniors are on medications that react poorly with caffeine — then caffeinated beverages are for the young, virile, and productive.
- Murray Carpenter, the author of the bookCaffeinated: How Our Daily Habit Helps, Hurts, and Hooks Us,says the rise of the coffee snob is part of the relatively newish, generational interest infancified versions of vices like craft beer and whiskey.
- We were drinking Budweiser; we didn’t have a million beers to choose from and if you went out to get coffee, it was probably Maxwell House.
But Carpenter says that’s based on an outdated assumption: “Some ofis a hangover from the fact that 20 or 30 years ago, people simply weren’t producing as much good coffee as they do now, and decaf was the less good version of that not very good coffee.” These days there are good decaf blends, although you probably won’t find them at Starbucks, or even your local cafe, or even maybe your grocery store.
- This part gets a little science-y, because to decaffeinate coffee beans is to conduct a rather complicated chemical process.
- These are not particularly gentle chemicals; the former can be used as a paint stripper or degreaser; the latter is often found in nail polish removers, which furthers the reputation of decaf coffee as “less natural” or worse.
- But the “purest” way to decaffeinate coffee is the Swiss Water process, in which the only chemical used is H2O.
- Guy Wilmot, a veteran coffee importer in West Sussex, England, began packaging and selling Swiss Water-treated coffee online in 2015 after developing a creeping intolerance to late-in-the-day caffeine and a lack of decent available options.
- The packaging for Decadent Decaf.
- They are, like the majority of decaf customers, older, generally between the ages of 45 and 60.
According to him, “it’s a little awkward in the coffee business.” “When I conduct tastings at events such as the London Coffee Festival, I’m a little worried about the tattoo crowd saying, ‘Oh, that’s not my thing.'” Wilmot is as perplexed as I am as to why decaf hasn’t taken off yet, though he does have a notion.
- “Take, for example, herbal teas, which are exploding in popularity.
- I truly believe that someone in the United States should take on this task.
- “Come on!” I exclaimed.
- CBD oil, vapes, gravity blankets, and fidget spinners are just a few of the things that have gone trendy in recent years.
- In light of this, coffee devoid of caffeine seems like a peculiar squandered opportunity to many people.
Richard Church worked at Starbucks in the mid-2000s, he was known as the “caffeine guy.” When CBS aired a show on the perils of “caffeine intoxication,” they interviewed Church, who explained that, no, cramming for an exam while chasing down black-market Adderall with six Red Bulls and a No-Doz and then getting smashed on Four Loko on the weekends was not, in fact, healthy.
- However, he must also keep up with current marketing trends.
- “It’s something that society has moved on from a little bit, and there are other, sexier things to be involved in,” he adds.
- Photograph courtesy of Nicky Digital/Corbis via Getty Images Vaping became extremely popular among teenagers as a result of aggressive marketing efforts — such as those run by Red Bull, for example.
- When I grumbled about the lack of cute caffeine-free coffee shops, you may recall that I was right.
- There was one of them.
- There were brewing and cupping demonstrations, live music, and local art for sale, all with the objective of “introducing and reminding New Yorkers to drink the coffee they love, simply without the caffeine,” according to the brand manager who spoke to NYU Local at the time of the launch.
The Washington Post reported that “the opening of an all-decaf coffee shop in Manhattan was received with fear and indignation.” The pop-up was deemed “the first symptom of the cultural apocalypse” by the Gothamist, which referred to its signature product as “fake coffee.” “Try Not to Scream: A Caffeine-Free Coffee Shop Has Just Opened,” wrote Jezebel in response to the headline.
In spite of poor coverage in the news and on social media, the firm claims that the event was a success for those who really went to see it.
As of right now, there is no military campaign against the nebulous menace to everyone known as Big Caffeine.
The reasons behind this are self-evident: Decaf continues to be associated with a negative connotation, both within the coffee industry and among working mothers on social media.
The more negative aspects of caffeine’s effects — such as anxiety, racing heartbeats, jitteriness, and nausea that slowly curdles in your stomach — will eventually outweigh the positive effects, and I have to assume this is true not only because I can no longer tolerate them.
Almost everything else that appears to occur in the world already provides us with all of these benefits. And, even if it works, what exactly is the point of caffeine anymore? Drink decaf coffee. Death, I assure you, is much, far worse than life.
