The actual caffeine content of any coffee drink varies by size, bean origin, roast method, and other factors, but a typical 28 grams (1 ounce) serving of espresso usually contains 64.5 milligrams of caffeine, whereas a typical (8 ounce) serving of drip coffee usually contains 150 to 200 mg. As a result of the pressurized brewing process, the flavors and chemicals in a typical cup of espresso are very concentrated.Įspresso has more caffeine per unit volume than most coffee beverages, but because its usual serving size (25-30 ml) is much smaller than (for example) drip-brewed coffee, the caffeine content of a single serving of espresso is generally lower than that of a mug of drip coffee. This is due to the higher concentration of suspended and dissolved solids, and the crema on top (a foam with a creamy consistency). It is also popular in Switzerland, Croatia, Bosnia and Herzegovina, Bulgaria, Greece, South Africa, the United Kingdom, the United States, Canada, Chile, Brazil, Australia, and New Zealand.Įspresso is generally thicker than coffee brewed by other methods, with a viscosity similar to that of warm honey.
