How much caffeine in a cup of coffee: Types, brands, and other sources

Coffee is a popular beverage that contains caffeine, and it is arguably the most prevalent source of caffeine. The amount of caffeine in a cup of coffee can vary significantly based on a number of factors, including the kind of coffee, the brewing technique, and the manufacturer. Caffeine-containing foods and beverages are consumed by more than 95 percent of individuals in the United States, according to the Dietary Guidelines for Americans 2015–2020. Adults in the United States consume between 110 and 260 milligrams (mg) of caffeine on a daily basis on average.

In this post, we’ll look at the caffeine concentration of a variety of different coffee kinds and brands to see how they compare.

There are many different sorts of coffee, each with its own quantity of caffeine. We’ll go through the caffeine concentration of some of the most popular forms of coffee in the next section:

Brewed coffee

Brew coffee, also known as filter coffee, is made by steeping ground coffee beans in hot water for an extended period of time. A paper, metal, or plastic filter is used to separate the grounds from the brewed coffee, and this mixture is typically used for this purpose. A variety of methods exist for brewing coffee, the most common of which are the use of filters, percolators, and French presses. A typical 8-ounce cup of freshly brewed coffee contains approximately 95 mg of caffeine.

Decaffeinated brewed

Despite its decaffeinated or decaf designation, coffee still contains a small amount of caffeine. For example, an 8-ounce cup of freshly brewed decaf coffee has around 2 mg of caffeine on average.

Cold brew

Cold brew coffee is distinct from iced coffee, which is merely the process of pouring brewed coffee over crushed ice. The coffee grounds are steeped in water at room temperature for anywhere between 8 and 24 hours in order to prepare cold brew coffee, according to the maker. According to a research conducted in 2017, a 12-ounce cup of cold brew coffee might contain anywhere between 153 mg and 238 mg of caffeine.

Instant coffee

Making this sort of coffee includes combining hot water with instant coffee powder or granules and brewing the mixture. Generally speaking, instant coffee has less caffeine than freshly brewed coffee. Approximately 62 mg of caffeine is contained in a normal 8-ounce cup of standard instant coffee.


A powerful coffee beverage made by pushing hot water or steam through very fine coffee grinds, espresso is a popular choice among coffee enthusiasts. If you want to make espresso coffee at home, you may use a machine or a stovetop moka pot. Because of the strong caffeine concentration of espresso, serving portions are typically substantially less than those of brewed coffee. Approximately 63 milligrams of caffeine are included in a single 1-ounce shot of espresso. Many coffee producers and chain restaurants publish estimates of the amount of caffeine contained in their coffee products on their websites.

Dunkin’ Donuts

Dukkin’ Donuts is a well-known coffee and doughnut business that offers a broad variety of caffeinated drinks to its customers. In accordance with the website Caffeine Informer, one medium cup (14 oz) of several of the coffee beverages available at Dunkin’ Donuts contains the following amount of caffeine:

  • Brewed coffee has 210 mg of caffeine
  • Decaf brewed coffee contains 10 mg of caffeine
  • An Americano contains 249 mg of caffeine
  • A cold brew contains 260 mg of caffeine
  • And a latte contains 119 mg of caffeine.

A single shot of espresso has 85 mg of caffeine.

Seattle’s Best

Retail storefronts and drive-thrus operated by Seattle’s Best Coffee, as well as several fast-food restaurants including Subway and Burger King, carry the company’s coffee goods. A small cup (12 oz) of several of this company’s coffee products provides the following amount of caffeine, according to Caffeine Informer:

  • Brew coffee has 260 mg of caffeine
  • Latte contains 75 mg of caffeine for both traditional and flavored variations
  • Mocha contains 80 mg of caffeine.

The caffeine content of a single shot of Seattle’s Best espresso is 75 milligrams.


Starbucks is one of the most well-known coffee brands in the world. Starbucks is headquartered in Seattle, Washington.

The caffeine level of the company’s coffee products, as well as other nutritional information, may be found in their online beverages menu. For example, certain Starbucks beverages have as much caffeine as the following in an 8-ounce tall cup (12-ounce serving):

  • Founded in Seattle, Washington, Starbucks is one of the world’s most well-known coffee companies. When you visit the company’s website, you’ll find the caffeine amount of their coffee goods, as well as other nutritional details. For example, certain Starbucks beverages have as much caffeine as the following in an 8-ounce tall cup (12-ounce cup):

A number of factors influence the amount of caffeine present in a cup of coffee. The kind of coffee bean is one of the most important considerations. There are many distinct kinds of coffee plant, and the caffeine level of coffee beans derived from different plants varies as a result. The following are the two most common species of plant used in the production of coffee beans:

  • Coffea arabica, sometimes known as Arabica, is a kind of coffee grown in Africa. Coffea canephora, also known as Robusta coffee, is a variety of the coffee plant.

According to a research conducted in 2016, Robusta coffee beans generally have around double the amount of caffeine found in Arabica coffee beans. The researchers discovered that Arabica beans have 34.1–38.5 g of caffeine per kilogram (kg) of dry coffee, but Robusta beans contain 68.6–81.6 g of caffeine per kilogram (kg) of dry coffee, according to their findings. A number of other factors can influence the quantity of caffeine in a cup of coffee, including but not limited to:

  • The kind of roast, the brewing technique, the amount of ground coffee that a person uses throughout the brewing process, and the serving size are all important considerations when making coffee.

Despite the fact that coffee is arguably the most well-known source of caffeine, this chemical may be found in a variety of different foods and drinks. The FDA, on the other hand, does not compel manufacturers to indicate the amount of caffeine included in packaged foods, drinks, or dietary supplements on their products. Below, we’ll go through some of the other popular sources of caffeine:


Various types of tea contain various amounts of caffeine, although the quantity in a cup of tea is normally less than in a cup of coffee of equal size. For example, an 8-oz cup of green tea has around 28 mg of caffeine, but the same serving size of black tea contains approximately 47 mg of caffeine (see chart).

Soft drinks

Soft drinks, such as sodas and fruit-flavored beverages, may contain small amounts of caffeine from time to time. For example, a 12-ounce can of Coca-Cola has around 33 mg of caffeine on average.

Energy drinks

Energy drinks can include extremely high concentrations of caffeine and sugar. Caffeine can come from a variety of sources, including synthetic and natural ones such as guarana leaves. It is important to note that the caffeine level of energy drinks varies greatly between brands. According to the Food and Drug Administration, the caffeine level of these beverages normally varies between 40 and 250 mg per 8 oz serving. Some energy drinks, on the other hand, can contain as much as 316 mg of caffeine per 8 oz serving.


Caffeine is naturally found in chocolate, however the quantity varies depending on the amount of cacao in the chocolate. Caffeine content in darker chocolate is often higher than that of lighter or milk chocolate. To give you an example, the caffeine content of a 1-ounce portion of chocolate is as follows:

  • 45–59 percent cacao solids: 12 mg
  • 60–69 percent cacao solids: 24 mg
  • 70–85 percent cacao solids: 23 mg
  • 90–100 percent cacao solids: 24 mg


Several over-the-counter and prescription drugs include caffeine, which can help to alleviate pain more effectively. Examples include Menstrual Relief Maximum Strength, which contains 500 mg acetaminophen, 15 mg pyrilamine maleate, and 60 mg of caffeine in a single capsule. Adults should drink no more than 400 mg of caffeine per day, according to the Dietary Guidelines for Americans 2015–2020 dietary guidelines. According to the Food and Drug Administration, there are no specific recommendations for children, however the American Academy of Pediatrics discourages children and adolescents from using caffeine.

They also caution that caffeine may have a greater effect on youngsters under the age of 12 because they tend to weigh less than their older counterparts.

Caffeine is usually considered to be harmless for the majority of individuals when consumed in moderation. Caffeine, on the other hand, might have negative side effects when used in excess. The following are examples of adverse effects:

  • Headaches, feeling restless or jittery, nervousness, anxiety, irritability, tremors, fast heartbeat, problems sleeping or sleeplessness, upset stomach, nausea, diarrhea, and frequent urination are all possible symptoms.

The amount of caffeine contained in a cup of coffee can vary significantly. The brewing process, the kind of bean, and the quantity of coffee grounds that a person uses are all factors that influence the caffeine level of a cup of coffee. A standard 8-oz cup of coffee has around 80–100 mg of caffeine, although other coffee beverages can have substantially more caffeine than this. Besides coffee, energy drinks, soft drinks, chocolate, and various pain relievers are all high in caffeine as well.

Spilling the Beans: How Much Caffeine is Too Much?

According to specialists at the Food and Drug Administration, caffeine may be a beneficial component of a balanced diet for the majority of individuals, but too much caffeine can be harmful to your health. Español Does your first cup of coffee or tea of the day include only a small amount of caffeine in the hopes that it would help you get through the rest of the day more quickly? Do you follow it up with a caffeinated beverage or two, and then go on to consume many more cups of coffee throughout the course of the day?

Learn more about caffeine by reading the questions and answers that follow.

1. Which kinds of foods and beverages contain caffeine?

In the plants that we use to create coffee, tea, and chocolate, caffeine may be found in their natural form. Additionally, it may be present in some plants that are used as flavorings, such as guarana, as well as in alternative South American teas, such as yerba mate (Ilex paraguariensis) andIlex guayusa (Ilex guayusa). Caffeine may also be used as an ingredient in a variety of food and beverage products.

2. How do you know how much caffeine a food or beverage contains?

Many packaged items, including beverages and nutritional supplements that contain caffeine, voluntarily disclose the amount of caffeine they contain on the label. This is done to protect consumers’ health. When consuming for the first time a new packaged product that has added caffeine, consumers should exercise caution, especially if the amount of caffeine in the meal is not specified on the packaging. Some foods and beverages, such as coffee and tea, contain high levels of caffeine, and there are various online databases that offer estimations of this content.

A 12 ounce can of caffeinated soft drink normally has 30 to 40 milligrams of caffeine, whereas an 8-ounce cup of green or black tea typically provides 30-50 mg, and an 8-ounce cup of coffee often includes 80 to 100 milligrams of caffeine.

Caffeine content in energy drinks can range from 40 to 250 milligrams per eight fluid ounces of beverage.

3. If a coffee or tea says “decaffeinated,” does that mean it contains no caffeine?

No. Decaf coffees and teas have less caffeine than their normal equivalents, but they still include a small amount of the stimulant. For example, an 8-ounce cup of decaf coffee generally contains 2-15 mg of caffeine. In the event that you have a serious negative reaction to caffeine, you may wish to avoid drinking these beverages completely.

4. How much caffeine is too much?

The Food and Drug Administration (FDA) has determined that 400 mg of caffeine per day (equivalent to four or five cups of coffee) is a quantity that is not commonly linked with harmful or negative effects in healthy persons. There is, however, a great deal of diversity in how sensitive people are to the effects of caffeine, as well as in how quickly they metabolize it (break it down). Certain medical disorders, as well as certain drugs, might make people more sensitive to the effects of caffeine.

Although the Food and Drug Administration has not established a limit for children, the American Academy of Pediatrics recommends that children and adolescents avoid coffee and other stimulants.

5. How do you know if you’ve consumed more caffeine than you can tolerate?

Caffeine overconsumption can result in the following side effects:

  • Insomnia, restlessness, anxiety, rapid heart rate, upset stomach, nausea, headache, and a general sensation of discontent (dysphoria) are all possible symptoms.

6. Does caffeine pose a danger to your health?

According to the FDA, hazardous consequences such as seizures can be detected after consuming around 1,200 milligrams of caffeine, or 0.15 teaspoons of pure caffeine, in a short period of time. Pure and highly concentrated caffeine products pose a substantial concern to public health and have been linked to at least two deaths in the United States in recent years. (In April, the Food and Drug Administration (FDA) took measures to safeguard consumers from these items. Often marketed as dietary supplements, these products are made up of pure or highly concentrated caffeine in powder or liquid form.

The risk of caffeine overdose grows as the concentration of caffeine in the product increases, which means that even tiny doses of a highly concentrated product might result in hazardous side effects if taken in excess.

These are hazardous concentrations that can have major health repercussions, including death, if consumed in large quantities.

7. Is it okay for kids to consume caffeine?

We urge that you get guidance from your child’s health care practitioner regarding his or her caffeine usage.

9. How can I cut back on caffeine without causing unpleasant side effects?

You should reduce your caffeine intake gradually if you are used to drinking caffeinated beverages on a daily basis and wish to reduce your intake. The rapid cessation of a drug might result in withdrawal symptoms such as headaches, anxiety, and anxiousness.

How Much Caffeine In a Cup of Coffee? (The Long Answer)

The long and complicated answer to the issue of how much caffeine is in a cup of coffee is that it varies. Which sort of coffee beans you choose, whether they’re light-roasted, medium-roasted, or dark-roasted, will determine how strong your coffee will be. It is dependent on the serving size, as well as on the brewing method that is used. A quick overview of the typical caffeine concentration in various coffee brewing techniques is provided below. Although there are variances between different types of coffee, as you can see from the table above, most cups of brewed coffee contain between 70 and 150 mg of caffeine on average.

  1. According to what we know, Devil Mountain Coffee has a staggeringly hazardous 1037 mg of caffeine every 8 oz.
  2. That is absolutely an excessive amount of caffeine!
  3. In addition to the brewing process, the type of beans used has a considerable influence on the amount of caffeine present.
  4. The Robusta coffee bean is more easily grown at lower elevations, and as a result, it is more commonly used in mass production.
  5. The Arabica coffee bean, on the other hand, is more difficult to cultivate and is typically planted at higher elevations.
  6. Robusta coffee beans generally have around double the amount of caffeine found in Arabica coffee beans.
  7. Furthermore, it is important to be aware that espresso drinks from commercial chain cafes generally contain more caffeine than espresso drinks from other coffee shops, which should be avoided.
  8. In the end, a cup of coffee is just that: a cup of coffee.
  9. As a result, the small cup (12 oz.) has 109 mg, the medium (16 oz.) contains 145 mg, and the large (21-24 oz.) contains 180 mg of caffeine.
  10. As a side note, Starbucks also offers keto-friendly beverages, including a flat black.

There you have it, your whole day’s worth of caffeine consumption crammed into one rather hefty coffee cup.

Caffeine in Decaf Coffee

When it comes to caffeine concentration in coffee beverages, one of the most often asked questions is: what about decaf coffee? Is it truly decaffeinated to its utmost extent? And the solution is almost perfect. Decaf coffee was accidentally discovered in 1905 when a shipment of beans was steeped in saltwater, which washed the caffeine out of the beans by accident. Since then, a variety of decaffeinating procedures have been developed, with the average decaffeinating process removing around 97 percent of the caffeine present in a specific coffee bean.

In other words, while an average cup of brewed coffee has around 95mg of caffeine, a decaf coffee contains far less caffeine, often around 2mg (although it can be as high as 7mg).

For those who are sensitive to caffeine, decaf is a reasonable alternative, but don’t go overboard with the decaf!

The fact that speciality coffee roasters are beginning to provide decaf coffee beans is an exciting development to observe in the industry.


After everything is said and done, we hope this article has been helpful in assisting you in understanding the caffeine level of ordinary coffee beverages. In summary, while the caffeine content of coffee varies depending on a variety of circumstances, a standard-sized cup of freshly brewed coffee typically contains between 70 and 150 mg of caffeine. This amounts to around one-quarter of the 400 mg of caffeine recommended daily consumption. A decaf coffee, on the other hand, contains far less caffeine, often about 2mg.

So, no, your morning cup of coffee is not slowly poisoning you.

Cheers to caffeinating!

How Much Caffeine Is in a Cup of Coffee? – Atlas Coffee Club

Having a cup of coffee in the morning or during an afternoon break is a necessary component of many people’s routine. Coffee, on the other hand, is more than just a daily pleasure. Its appeal can be attributed in part to the fact that it is a mild stimulant as well. When used in moderation, coffee may be a pleasant way to jump-start your morning or help you through a lull in the afternoon. However, there is such a thing as getting too much of a good thing. When you know how much caffeine is in each variety of coffee, you can better control your caffeine intake and ensure that you’re not getting too much of a good thing at one time.

Recommended Levels of Caffeine Consumption

Approximately 400 mg of caffeine can be consumed each day by a healthy adult, according to the Mayo Clinic. However, a variety of factors, such as taking drugs, being pregnant, and being sleep deprived, might have an impact on this figure. According to the Mayo Clinic, 400 mg of caffeine is equivalent to around four 8-ounce cups of drip or filter coffee each day.

The Potential Side Effects of Too Much Caffeine

Excessive coffee consumption might theoretically result in an excess of stimulation. When you consume too much caffeine, you may experience a variety of unpleasant side effects, including jitteriness, anxiety, and problems sleeping. High blood pressure and an accelerated heart rate are two of the most dangerous possible side effects to be concerned about. Caffeine, in addition, is regarded to be an addictive substance, and it is classed with other “Schedule 1” narcotics such as cocaine and amphetamines.

This means that we can’t replace sleep with coffee (no matter how much we want to)!

Coffee consumed late in the day may make it difficult to fall asleep at night, according to some studies.

Given the addictive nature of caffeine, abruptly lowering your caffeine intake might result in withdrawal symptoms such as tiredness and headaches.

The Health Benefits of Caffeine

There is also a slew of good news for coffee aficionados to take advantage of. Recent research, according to Harvard Medical School, reveal that drinking coffee may have a beneficial effect on one’s health. Coffee users may have a lower chance of developing Alzheimer’s disease, diabetes, Parkinson’s disease, some forms of cancer, heart attacks, strokes, and liver disease, among other diseases and conditions.

Additional advantages include enhanced physical performance as well as the ability to counteract the consequences of physical effort.

How Much Caffeine Is in a Cup of Coffee?

The caffeine content of an 8-ounce cup of coffee can range from 90 to 200 milligrams per cup. The quantity of caffeine in a caffeinated coffee drink might vary significantly from one brand to another. Even decaf coffee does not contain zero caffeine; in fact, decaf contains a trace amount of caffeine. The large variation is due to the fact that each batch of coffee produced will have a varied quantity of caffeine based on the following factors:

  • The type of coffee bean used
  • Technique of brewing (drip, percolated, French press, etc.)
  • Ingredients
  • It doesn’t matter what kind of grind you use (coarse or fine)
  • The amount of ground coffee that is being consumed

Let’s take a closer look at each of these aspects.

Type of Coffee Bean

Arabica coffee beans have far less caffeine than their counterparts, Robusta coffee beans. In fact, Robusta beans have roughly double the amount of caffeine than Arabica beans. If you want to drink more than a couple of cups of coffee a day, Arabica beans are the best choice for you. Arabica beans, with their more complex taste profile and hints of crisp acidity, provide a more nuanced coffee drinking experience that is also more enjoyable to consume more frequently.

Brewing Method

The technique of extraction you choose to brew your coffee has an impact on the quantity of caffeine that is present in your cup. When using immersion methods, such as combining ground coffee with cold or hot water, you will often extract more caffeine. However, the coarser grinds that are preferred for immersion procedures have less surface area than coffee that has been finely ground. The quantity of caffeine extracted is reduced as a result of this. French press coffee has a small lower caffeine content per serving than drip or filter coffee because of the way it is made.

When making cold brew coffee, the coarse-ground coffee is left in contact with the water for an extended period of time.

Cold brew is frequently made as a coffee concentrate that is intended to be diluted.

Because of this, it may be simpler to consume a stronger cold brew and so consume an excessive amount of caffeine.

Type of Roast

Darker roasts provide a fuller body and more intense tastes of chocolate, almonds, and caramel than lighter roasts. However, while darker roasts have a robust flavor, they do not always have a high caffeine content. In reality, light roast coffees contain somewhat more caffeine than dark roast coffees.

Serving Size

This appears to be far too clear, but it is quite easy to ignore. Every 8-ounce cup of brewed coffee has roughly 100 milligrams of caffeine, which is the amount stated in the previous sentence. The fact that we live in a culture where serving sizes are sometimes too large, combined with the fact that many fast food restaurants also provide coffee, means that coffee amounts can frequently surpass 8 ounces. You could be sipping on a 12-ounce cup of coffee, or even a 14- to 16-ounce cup, depending on your preference.

It is likely that even your favorite coffee establishment will provide regular servings that are greater than 8 ounces. The number of cups of coffee you can consume in a day is highly dependent on the size of the cup.

Caffeine Content in Espresso

Because of the high concentration of caffeine in espresso, it is easy to underestimate the quantity of caffeine consumed. There is a distinction between espresso and coffee in terms of flavor and strength. Yes, a shot of espresso is a teeny-tiny amount of liquid. However, the caffeine concentration of a 1-ounce shot of espresso is approximately half that of an 8-ounce cup of coffee. Espresso drinkers will quickly hit their daily caffeine limit if they consume the beverage in large quantities.

Steamed milk does not reduce caffeine intake; rather, it lessens the bitterness of the beverage and, therefore, may reduce your impression of how much caffeine you are actually consuming.

Other Caffeinated Beverages and Sources of Caffeine

Coffee is not the only source of caffeine that may be found in the average person’s everyday life. Caffeine may be found in both black tea and green tea. Caffeine may be found in a variety of beverages, including soft drinks. Energy drinks can contain an equal amount of caffeine as coffee, and in some cases, even more caffeine than coffee. For those still on the fence about whether to drink coffee or an energy drink, have a look at our comparison of coffee vs. energy drinks for more information.

It is possible to consume considerable levels of caffeine through the consumption of chocolate, particularly chocolate that contains a high proportion of cocoa solids.

Of course, any of these additional sources of caffeine might contribute to your daily caffeine quota, lowering the quantity of coffee you can consume.

Caffeine in Your Favorite Coffee Drinks

There is widespread agreement on the caffeine content of popular coffee preparations, and these amounts serve as a solid starting point for estimating your daily caffeine intake. As you’ll see, the brewing procedure has a significant impact on the final product:

  • Percolated coffee contains 200 mg of caffeine per 8-ounce serving
  • Filter or drip coffee contains 95-165 mg of caffeine per 8-ounce serving The caffeine content of an 8-ounce cup of French press coffee is 107 mg
  • The caffeine content of an espresso shot is 47-64 mg. A 12-ounce dose of cold brew coffee has 150 milligrams of caffeine.

The Bottom Line

It is not always easy to accurately determine the quantity of caffeine contained in a serving of coffee, especially when considering the several factors described above. Pay close attention to how coffee affects your mood. Consider minimizing your coffee intake, or at the very least restricting your coffee consumption to the morning and early afternoon hours if that extra cup of coffee is making you jittery or if you’re not sleeping as soundly as you’d like. When it comes to enjoying coffee to its fullest and ensuring that it is a pleasant part of your day, moderation is essential.

This may be accomplished without sacrificing the enjoyment of drinking coffee.
