Coffee is more than a beverage — it’s your fuel for the day, and sometimes, even into the late hours of the night. Some say caffeine makes the world go round, and we couldn’t agree more. However, as responsible adults, it’s important for us to acknowledge how much caffeine we’re putting in our bodies and understand how much caffeine is too much caffeine.
We’ve created this quick guide to help you learn how much caffeine is in a cup of coffee, what types of coffee has the most caffeine, which roast has the most caffeine and how much caffeine is in single-serve cups.

What’s the Amount of Caffeine in Coffee Pods?
Coffee Pods and other coffee pods are easy to use. Pop in, heat up and drink down — you’re caffeinated and ready to go before you know it. Because it’s so simple and effortless, you can quickly grab multiple cups of fresh coffee throughout the day at your convenience. Unfortunately, that also means that it can be easy to over-caffeinate yourself if you aren’t aware of the caffeine content of each cup. Or you may wonder why a single pod of one brand doesn’t revitalize you as well as another.
Many coffee pods will have different levels of caffeine. In fact, some coffee pods made by the same brand may have higher or lower caffeine contents than other alternatives manufactured under the same company. Let’s use Starbucks as an example. Starbucks cups for Keurig pods have the following amount of caffeine:
- Standard pod: 130mg per 8 fluid ounces
- Plus pod: 260mg per 8 fluid ounces
- Verismo pod: 40 to 45mg per 12 fluid ounces per espresso pod, 50 to 60mg per 16 fluid ounces per brewed pod.
These three different coffee pods manufactured by the same brand have varying levels of caffeine. Although a plus pod produces a smaller volume of coffee, its caffeine content is much higher than a higher volume of the espresso pod. Let’s compare a few other brands. Many Keurig Coffee pods will contain between 75 to 150mg while many Nespresso capsules will have 50 to 80mg. Nespresso Kazaar capsule, however, can have as much as 120mg of caffeine.
Why is it important to know the amount of caffeine in coffee pods? Although you don’t necessarily need to make your morning mug decisions based on a coffee pod caffeine chart, you should understand that there’s a difference between a cup of coffee produced from a single-serve cup, a cup of coffee purchased from a cafe, a bottled or canned coffee beverage and the standard cup of coffee you grind and brew at home. Each of these four coffee categories can contain varying levels of caffeine.
How Much Caffeine Is in a Standard Coffee?
To discover how much caffeine is in a standard cup of coffee, we must first define what a standard cup of coffee is. Most people agree that a regular cup is an 8-ounce pour of brewed coffee. Though there are many different coffee brews from different brands, most 8 ounce cups should contain around 100mg of caffeine. However, a “standard” cup for one person may include an espresso shot while the go-to cup for another is a cold brew. Let’s look at caffeine content via brewing methods:
- Instant coffee: 27 to 173mg for caffeinated, 2 to 12 for decaf, per 8 ounces.
- Percolated coffee: 80 to 135mg per 5 ounces.
- Fresh Press coffee: 80 to 135mg per 8 ounces.
- Boiled coffee: 160 to 240mg per 8 ounces.
- Cold brew: Cold brew coffees are unique in that they usually are brewed with a higher water-to-coffee ratio than a standard brew of hot coffee. Depending on its level of concentration, cold brew coffee could have less, more or an equal amount of caffeine compared to standard cups. For example, one brand’s cold brew may contain 200mg while their hot coffee of the same size contains as much as 360mg. If the cold brew is not cut with water or milk, its caffeine volume per glass could increase.
- Espresso: An espresso shot does not normally contain more caffeine than a standard cup of coffee but there is a greater volume of caffeine per ounce. A single glass containing three espresso shots, however, may contain more caffeine per volume than a standard cup of black coffee. The average caffeine content in an espresso shot may be roughly 63mg.
Before we discuss how the actual types of beans, roasts and volume impact caffeine levels, you should know that even a standard cup of coffee can be significantly different from cafe to cafe in terms of caffeine content. Each cafe you visit may offer sizes that are similar in name but different in volume. Instead of comparing Let’s compare the caffeine content in three coffee brands, Starbucks, McDonald’s and Dunkin, in regards to their 16-ounce, espresso, and decaf offerings. Here’s a quick coffee caffeine chart:

For a 16-ounce cup of coffee, caffeine contents are:
- Starbucks: 330mg
- McDonald’s: 145mg
- Dunkin: 302mg
For espresso or an espresso-based drink:
- Starbucks: 150 to 225mg
- McDonald’s: 71mg
- Dunkin: 75mg
For a cup of decaf coffee:
- Starbucks: 8 to 14mg
- McDonald’s: 8mg
- Dunkin: 7mg
What Types of Coffee Have the Most Caffeine?
Coffee is great for your body, as it contains antioxidants, boosts morale and productivity and has been shown to positively impact major organs in the body including the brain, heart, and liver. Caffeine in coffee also has potential health benefits, ranging from increased memory and reduced chronic inflammation to potentially reducing your risk for kidney stones, cancer, liver fibrosis, Alzheimer’s and Parkinson’s disease. By responsibly controlling your caffeine intake, you can potentially experience these health benefits.
Although any potential benefits to our health are welcomed, let’s be honest — most of us drink coffee to make it through the day. Whether it’s a day spent studying, working at the office or raising children, the caffeine in coffee gives us the energy, focus, and stamina we need to do whatever we’ve got to do. Knowing which types of coffee have the most caffeine can help you choose the right cup that’ll help you conquer the day.
It’s good to know how one type of coffee’s caffeine content compares to another’s, but it’s more interesting to understand why all coffees don’t have the same level of caffeine. Coffee is made from coffee beans — shouldn’t the caffeine content be the same regardless of how it’s prepared? The art of taking coffee beans and creating a brew is a lot more scientific than you may think. In fact, just understanding the roasting process is enough to change the way you think about caffeine in coffee.

Do Light Roasts or Dark Roasts Have More Caffeine?
A cup of a light roast, medium roast, and dark roast will each have a different taste, but does that mean the caffeine content is different as well? Many coffee drinkers are interested to understand how the light roast caffeine levels compare to the dark roast caffeine levels. One major misconception about coffee is the assumption that darker roasts have higher caffeine contents. This way of thinking assumes that dark roasts will always have more caffeine than a medium roast which will have more caffeine than light roasts.
The answer to this question is tricky — which roast has the most caffeine? It all depends on how you’re comparing the roasts. Coffee beans are roasted for varying lengths of time to produce the desired flavor. Chemically speaking, caffeine itself is stable through the actual roasting process, but the coffee beans are not. Although the caffeine content of one roast may be different than another, it’s not because of the degree the beans are roasted to — it all has to do with the weight of the beans after roasting.
Any bean undergoing the roasting process will immediately begin to lose its water content. This causes the bean itself to become less dense and larger in size. Comparing dark roast caffeine and light roast caffeine, dark roast beans will be roasted longer which causes them to lose density and gain size. In contrast, light roasted beans don’t experience such a duration of heat so they will be denser and smaller than dark roasted beans. Thus, dark, medium and light define flavor profiles, not caffeine contents.

Because light roasts are roasted for the shortest length of time, they actually have slightly more caffeine than dark roasts. They may not taste as strong as a dark roast, but their caffeine content is slightly stronger. However, the roasting process isn’t the driving force that dictates how much caffeine content is in the light or dark roast you drink at home. The volume and weight of the light, medium and dark roasted beans are actually the culprits.
How Weight and Volume Impact Caffeine Content
Once the coffee beans are roasted, they can be measured according to weight or volume. If you were to compare the caffeine content in a single scoop of dark roasted beans to light roasted beans in terms of volume, light roasted beans would have more caffeine than dark because there would be more beans in your scoop. However, if you brewed two pounds of dark roasted beans and compared them to a single pound of light roasted beans, the dark roast would have more caffeine content by weight.
How Grinding Influences Caffeine Content
The caffeine content in each cup you prepare may also be influenced by how the coffee is ground. The size of your grind and how long you grind it may actually make a difference. One study showed that 42 seconds was the ideal length of time to grind your beans to yield the optimal amount of caffeine. There is a dramatic increase in caffeine content between 10 and 40 seconds of grinding time, then caffeine content stopped increasing after 42 seconds.
Do Coffee Beans Themselves Have Different Caffeine Contents?
Even before the roasting and brewing process occurs, the coffee beans themselves have different levels of caffeine content. The two beans you are likely most familiar with are Arabica and Robusta beans. Arabica beans have roughly 1.5% caffeine while Robusta beans contain 2.4% caffeine. Here are a few other examples of caffeine contents in different beans from around the world:
- Colombia Supremo: 1.37% caffeine
- Ethiopian Harrar-Moka: 1.13% caffeine
- Mexico Pluma Altura: 1.17% caffeine
- Mocha Mattari from Yemen: 1.01% caffeine
- Tanzania Peaberry: 1.42% caffeine.
How Much Caffeine Is Too Much Caffeine?
Is there any such thing as too much caffeine? Yes, although most people don’t experience severe adverse health issues or conditions due to too much caffeine. While caffeine can affect each person in different ways, most people can consume anywhere between 400 to 600mg of caffeine per day without experiencing any issues. Depending on the type of coffee and volume you consume, this can equal roughly four to six standard cups. However, you should also be aware that caffeine is found in other foods and beverages too.
A cup of warm tea can have between 20 to 45mg of caffeine while iced tea may contain 10 to 50mg. Sodas may contain between 20 to 60mg of caffeine while energy drinks may contain as much as 120mg per serving. Hot chocolate and milk chocolate typically have single-digit caffeine averages but dark chocolate can also exceed 100mgs. Learning how to balance your caffeine intake includes managing the caffeine found in coffee as well as other sources.
Whether you rely on your coffee pods caffeine content to get you through the day or if you prefer to brew your own batch of coffee at home with the best Arabica beans in the world, there’s no denying the fact that caffeine is king for most coffee drinkers. However, not every cup of coffee contains the same content of caffeine. When choosing your cup every morning, be sure you’re selecting the types of coffee that have the level of caffeine you need to keep you functioning optimally.
