How Much Caffeine Is in Coffee & Espresso?

The average cup of coffee contains about 100 milligrams of coffee, but there is a lot of variation. An espresso often contains as little as 50 milligrams per shot, while a cup of drip coffee can easily contain 200 milligrams of caffeine.

Determining the caffeine levels of coffee and espresso drinks can be very tricky. But you need to know whether that cup has enough caffeine to help you wake up, while not exceeding the recommended 300 milligrams per day. There are many factors that influence the caffeine levels in different coffee drinks, such as espresso, French press coffee, and drip brewed coffee. Learn why caffeine levels vary and see a list of caffeine levels in different coffee drinks, including Starbucks coffee caffeine levels.

Caffeine Levels of Coffee Roasts

Many people believe that darker coffee roasts have more caffeine because they have a stronger flavor. However, darker roasts generally have lower caffeine levels than lighter roasts. This is because the prolonged heat of heavier roasting breaks down the caffeine molecule, or as some people like to put it, roasting “burns off the caffeine.” If you’re not sure of your coffee’s roast, just look at the color. A lighter color means a lighter roast and more caffeine.
