Coffee and espresso are two of the most popular beverages around the world. Whether you enjoy a cup of coffee in the morning to start your day, or an espresso after a meal to cap off your night, caffeine plays a central role in our day. But have you ever stopped and wondered just how much caffeine is in your favorite cup of coffee or espresso?
Coffee is a stimulant that contains caffeine, which is known to increase alertness and improve mental clarity. Some people are more sensitive than others to the effects of caffeine.
In the United States, a standard cup of coffee is typically measured as 8 fluid ounces, which is equivalent to 240 milliliters.
– Decaffeinated coffee: typically contains less than 5 milligrams of caffeine per 8-ounce cup. – Light roast coffee: typically contains 65 to 90 milligrams of caffeine per 8-ounce cup.
Depending on the strength and size of the cup, an 8-ounce cup of drip coffee can contain anywhere from 65 milligrams to 120 milligrams of caffeine.
The brewing method affects the caffeine content; generally, longer brewing times and hotter water result in higher caffeine content.
On average, a single shot of espresso contains approximately 40-50 milligrams (mg) of caffeine.
