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.

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 combination is often used for this purpose.

A multitude of methods exist for brewing coffee, the most common of which are the use of filters, percolators, and French presses. A average 8-ounce cup of freshly brewed coffee has around 95 milligrams 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):

  • Pike Place roast: 235 mg
  • Decaf Pike Place roast: 20 mg
  • Cold brew with cold foam: 155 mg
  • Caramel macchiato: 75 mg
  • Cappuccino: 75 mg
  • Pike Place roast: 235 mg

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.

How Much Caffeine in a Cup of Coffee? A Detailed Guide

In terms of caffeine intake, coffee is the most common food source. An average cup of coffee will provide you with around 95 mg of caffeine on average. However, the quantity of caffeine in different coffee drinks varies, and can vary anywhere from practically nothing to more than 500 mg per cup. This is a comprehensive guide on the caffeine level of various types and brands of coffee, including espresso.

What Factors Affect Caffeine Content?

The caffeine concentration in coffee is determined by a variety of factors, including:

  • Coffee bean types: There are many distinct varieties of coffee beans available, each of which may naturally have a varying quantity of caffeine. Roasting: Lighter roasts contain more caffeine than darker roasts, despite the fact that darker roasts offer a more complex flavor. Type of coffee: The caffeine level of various types of coffee, including conventional brewed coffee, espresso, instant coffee, and decaf coffee, can differ greatly. Serving size: The volume of “one cup of coffee” can range from 30–700 mL (1–24 oz), which has a significant impact on the overall caffeine level.

Bottom Line: The amount of caffeine in a cup of coffee is determined by the type of coffee bean used, the roast style used, how the coffee is made, and the serving size.

How Much Caffeine Is in a Cup of Coffee?

The sort of coffee you consume is the most important factor in determining its caffeine concentration.

Brewed Coffee

In the United States and Europe, brewing is the most frequent method of preparing coffee. The process of brewing coffee, sometimes referred to as ordinary coffee, involves pouring hot or boiling water over ground coffee beans, which are typically enclosed in a filter. One cup of freshly brewed coffee (8 oz) has around 70–140 mg of caffeine, or an average of 95 mg per cup ( 1 ,2).


Using a modest amount of hot water or steam, espresso is created by pressing the beans through a finely ground coffee grinder. Despite the fact that espresso has more caffeine per volume than normal coffee, it often contains less caffeine per serving due to the fact that espresso portions are typically tiny. A single shot of espresso is typically 30–50 mL (1–1.75 oz) in volume and contains around 63 mg of caffeine ( 3 ). As a result, a double shot of espresso contains around 125 milligrams of caffeine.

Espresso-Based Drinks

Many popular coffee beverages are produced by combining espresso shots with a variety of milk kinds and quantities in various proportions. Lattes, cappuccinos, macchiatos, and Americanos are examples of such beverages. Because the milk does not include any extra caffeine, the caffeine content of these beverages is the same as that of a cup of plain espresso. A single (small) cup of coffee has around 63 mg of caffeine on average, whereas a double (large) cup contains approximately 125 mg.

Instant Coffee

Instant coffee is created from brewed coffee that has been freeze-dried or spray-dried, and it is available in many flavors. It is often found in huge, dry chunks that disintegrate when exposed to water.

The simplest way to make instant coffee is to combine one or two tablespoons of ground coffee with hot water. There is no need to prepare any beverages. Caffeine content in instant coffee is often lower than that of normal coffee, with one cup containing around 30–90 mg of caffeine ( 4 ).

Decaf Coffee

However, despite the fact that the name implies otherwise, decaf coffee does not contain zero caffeine. This beverage can include variable quantities of caffeine, with the average cup holding 3 mg. The caffeine content can range from 0–7 mg per cup, with the lowest cup containing 0 mg ( 5 , 6 , 7 ). However, depending on the kind of coffee, the technique of decaffeination used, and the size of the cup, some variations may have even greater levels of caffeine than others. The bottom line is this: The typical caffeine level of an 8-ounce cup of freshly brewed coffee is 95 milligrams (mg).

Are Commercial Brands More Caffeinated?

The caffeine content of some commercial coffee brands may be higher than that of conventional, home-brewed coffee. Coffee shops are especially well-known for serving huge cups of coffee, which may be as much as 700 mL in size (24 oz). The amount of coffee included in such cups is approximately the same as 3–5 regular-sized cups of espresso.


Starbucks is, without a doubt, the most well-known coffee establishment in the entire globe. It also serves some of the most highly caffeinated coffee available on the market. The caffeine concentration of brewed coffee at Starbucks is as follows (8,9): caffeine content:

  • 180 mg for a short (8 oz)
  • 260 mg for a tall (12 oz)
  • 315 mg for a grande (16 oz)
  • 415 mg for a venti (20 oz).

In addition, one shot of espresso at Starbucks has 75 milligrams of caffeine, which is considered moderate. As a result, all small espresso-based beverages include 75 milligrams of caffeine per serving. This comprises beverages such as lattes, cappuccinos, macchiatos, and Americanos, among other things (10). Larger versions (16 oz), which are created with two or three espresso shots (16 oz), also include 150 or 225 mg of caffeine, depending on the size. Starbucks decaf coffee has 15–30 mg of caffeine per cup, depending on the size of the cup.

The caffeine content of a single espresso and espresso-based beverages is 75 mg, but an 8-ounce cup of decaf coffee contains around 15 mg of caffeine.


Almost everywhere in the globe, McDonald’s offers coffee under the McCafe brand; the company also sells tea. Even though they are a major fast food corporation that sells coffee, they do not standardize or quantify the amount of caffeine in their beverages. According to our calculations, the caffeine concentration of their brewed coffee is around (11):

  • A small (12 oz) serving has 109 mg of sodium
  • A medium (16 oz) serving has 145 mg of sodium
  • A large (21–24 oz) serving has 180 mg of sodium.

Its espresso includes 71 mg of caffeine per serving, while its decaf contains 8–14 mg, depending on how big a cup you have. The bottom line is that McDonald’s does not standardize the quantity of caffeine contained in its coffee beverages. According to our calculations, a small cup of freshly brewed coffee has 109 mg of caffeine. Espresso has around 71 mg of caffeine, whereas decaf includes approximately 8 mg.

Dunkin Donuts

Dunkin Donuts is another another coffee and doughnut store business that is extremely popular all over the world.

It has the following amount of caffeine (12) in their freshly brewed coffee:

  • 215 mg for small (10 oz)
  • 302 mg for medium (16 oz)
  • 431 mg for large (20 oz)
  • And 517 mg for extra large (24 oz).

One of their espresso shots has 75 mg of caffeine, which is also the amount of caffeine you can anticipate to get from one of their espresso-based beverages. The decaf coffee served at Dunkin Donuts may also contain a significant amount of caffeine. According to one source, a small cup (10 oz) of coffee has 53 mg of caffeine, while a large cup (24 oz) contains 128 mg of caffeine (13). That’s nearly as much caffeine as you’ll get in most other types of normal coffee, if not more. A small cup of Dunkin Donuts coffee has 215 mg of caffeine, whereas a single espresso contains 75 mg.

Is Caffeine Something to Worry About?

Coffee is abundant in antioxidants, and several studies have shown that coffee is beneficial to one’s health. Getting too much coffee, on the other hand, has been related to negative side effects such as anxiety, sleep interruptions, heart palpitations, and restlessness ( 14 , 15 ). Caffeine consumption of 400–600 mg/day is typically not related with any negative effects in the majority of persons. This equates to around 6 mg per kilogram (3 mg per pound) of body weight, or 4–6 typical cups of coffee per day ( 16 ).

Some people are extremely sensitive to it, while others are completely unaffected by enormous doses of it.

It’s simply a matter of trial and error to determine the appropriate amount.

Staff at the Mayo Clinic When it comes to grownups, caffeine is likely to be a part of their daily routine. Do you, on the other hand, know how much caffeine is in your favorite beverages? The use of up to 400 mg of caffeine per day is deemed harmless for the majority of individuals. Caffeine sensitivity, on the other hand, differs from person to person. Consider cutting back on your caffeine use if you’re experiencing symptoms such as headaches, insomnia, or anxiety.

How Much Caffeine in a Cup of Coffee?

The amount of caffeine in coffee is determined by a variety of factors. You may have ever pondered how much caffeine is included in that cup of coffee or espresso that you are currently consuming. A average shot of espresso includes around 40-50 milligrams of caffeine, and a regular cup of coffee contains approximately 100-120 milligrams of caffeine, to give you an idea. The solutions provided here, however, are not 100 percent correct. According to the USDA, a typical cup of brewed coffee will contain on average 11.8 mg of caffeine per fluid ounce of brewed coffee on average.

If a 12-cup coffee maker is used, 60 fluid ounces of coffee will be brewed.

You might be interested in our post on how much coffee is in a cup for additional information.

Of course, the exact amount of caffeine depends on a variety of factors, including the type of coffee beans you use (Robusta beans contain significantly more caffeine thanArabica beans), the type of coffee brewing method you use (roasted coffee beans contain less caffeine than unroasted coffee beans), the extraction time and water temperature, among other considerations.

Caffeine Content by Single Origin

Single Origin: Percentage of the total (by weight)

  • Ethiopian Harrar-Moka: 1.13 percent
  • Guatemala Antigua: 1.32 percent
  • Indian Mysore: 1 percent
  • Jamaican Blue Mtn/Wallensford Estate: 1.20 percent
  • Kenya AA: 1.36 percent
  • Kona Extra Prime: 1.32 percent
  • Mexico Pluma Altura: 1.17 percent
  • Yemen Mocha Mattari: 1.01 percent
  • New Guineese: 1.01 percent

(From the Mountainos Bros. Coffee Co. newsletter, published in San Francisco.) Example: If you use 10 grams (10,000 mg) of coffee (about 2 tablespoons) that contains 1.20 percent caffeine by weight, you will receive around (10,000 mg * 0.012 =) 120 mg of caffeine. Please keep in mind that not all brewing processes remove 100 percent of the caffeine from the water. For example, espresso brewing methods (high pressure, high temperature) extract almost double the amount of caffeine extracted by ordinary drip brewing methods (low pressure, low temperature).

This set of figures may be accurate for the coffee sold by Mountanos Bros.

Caffeine concentrations will differ from farm to farm, plant variety to plant variety, and even year to year depending on the growing conditions.

What is the best way to pick a coffee depending on the caffeine content? In no way, shape, or form. The flavor of the coffee should be considered when selecting it. If you feel the urge for additional caffeine, simply drink another cup.

Does a Medium Roast have more caffeine than a Dark Roast?

Because coffee roasting only slightly reduces the quantity of caffeine in the bean, the caffeine level of a light roast, medium roast, and dark roast will be indistinguishable from one another. There are myths about both light and dark roasts, with some stating light roasts contain more caffeine (which is only marginally accurate), and others claiming dark roasts contain more caffeine (which is likely due to a more developed “coffee” flavor), but good old science comes to the rescue here: Caffeine did not degrade significantly, with just 5.4 percent of its potency being lost after being subjected to extreme roasting.

Source Green coffee loses anywhere from 10% to 20% of its weight during the roasting process due to evaporation of water, hence darker roasts may or may not have a minor advantage in caffeine content when comparing exact weights after roasting.

Does Robusta have more caffeine than Arabica coffee?

Robusta has nearly double the amount of caffeine found in arabica, according to a conventional rule of thumb. If you are comparing arabicabeans to robustabeans, the results will differ based on which arabicabeans you are comparing them to. A chemical analysis of materials submitted to a lab will be the only method to determine this for certain.

How Much Caffeine in a Cup of Coffee

Although the earliest coffee shops were established in Istanbul, Damascus, and Syria as early as 1530, it was not until 1819 that a German scientist called Friedlieb Runge was able to extract caffeine. The caffeine found in nature acts as a natural insecticide, assisting plants in their defense against predators such as dangerous insects. When caffeine is eaten, it causes an increase in alertness and energy due to its capacity to imitate adenosine, a chemical that attaches to the adenosine receptors in the brain.

The upshot of this is that actual adenosine is prevented from doing its role of causing sleepiness and causing nerve impulses to slow down, as a result of the blockage.

  • A conventional 43-gram Hershey’s Milk Chocolate bar includes approximately 10 milligrams of caffeine
  • A typical cup ofDecaffeinated Coffeecontaining around 7 ounces will likely have approximately 10 milligrams of caffeine
  • And a cup of Teacontaining approximately 10 milligrams of caffeine. A 6 ounce cup of black tea will likely have around 50 milligrams of caffeine, whereas a 6 ounce cup of green tea will likely contain approximately 30 milligrams of caffeine
  • A 12 ounce Coke will contain approximately 34 milligrams of caffeine.

Caffeine may be chemically produced, albeit this is not usually done due to the ease with which caffeine can be obtained as a by-product of decaffeinating items that contain caffeine, such as coffee beans, and the high cost of doing so. If you’re wondering how much caffeine is in a cup of coffee because you’re concerned about your overall caffeine intake, keep in mind that there are a variety of factors to consider. Also, keep in mind that Instant Coffee is typically made with Robusta coffee beans, which contain approximately twice the amount of caffeine found in Arabica coffee.

Caffeine Impact on Health

Coffee has just a minor effect on the body in general, and moderate doses do not produce the issues associated with excessive caffeine use. Caffeine, on the other hand, is inversely associated with all-cause morality: This suggests that people who drink coffee have a reduced risk of dying in a given year than people who do not drink coffee. Although the specific mechanism (antioxidants, lifestyle variables, or increased alertness) is uncertain, the general agreement is that drinking coffee is beneficial to one’s health.

You might also experiment with decaffeinated coffee.

When utilizing the French Press brewing technique with strong coffee beans, one cup of coffee can contain significantly more caffeine than a cup of coffee that has been mildly brewed, therefore you may want to experiment with using less grinds when preparing your coffee.

Caffeine is metabolized by the body’s liver once it has been taken, and it is absorbed by the stomach and small intestine in less than an hour, following which it spreads throughout the body’s tissues.

Caffeine in Single Origin Coffee Beans

If you want to create a significant change in the caffeine level of a mix, you should use Robusta beans rather than experimenting with different forms of Arabica. However, the mix should not be decided by how much caffeine can be squeezed out of it – flavor will always take precedence over caffeine content.

Some Caffeine Stats

Caffeine has the chemical formula C8H10N4O2 and the chemical name 1,3,7-trimethylxanthine. It is found in around 60 different plants, with the chemical name 1,3,7-trimethylxanthine being the most common. Every day in the United States, over 450,000 cups of coffee are drank. The majority of people obtain their caffeine from either coffee beans or tea leaves, or from other drinks that contain caffeine that has been extracted, or from diverse natural sources like as cocoa beans, the kola nut, the Yaupon Holly, yerba mate, and guarana berries, among others.

Caffeine in Folgers Black Silk

Folgers Black Silk contains approximately the same amount of caffeine as normal Folgers coffee. As previously stated, only around 5% of the caffeine content of coffee is lost during the roasting process from a light roast to a dark roast. Even though Folgers Black Silk is a very dark roasted, strong-tasting coffee, it will not contain considerably less caffeine than other coffees on the market. Folgers coffees contain 30-40 milligrams of caffeine per tablespoon of ground coffee, which translates to 60-80 milligrams of caffeine every 12-ounce serving of brewed coffee.
