If you’re like most adults, caffeine is part of your daily routine. But do you know the caffeine content of your favourite drinks?
What factors affect caffeine content?
The caffeine content of coffee depends on many factors, such as the following:
- The type of coffee beans: There are many varieties of coffee beans available, which may naturally contain different amounts of caffeine.
- Roast: Lighter roasts have more caffeine than darker ones, although the latter have a deeper flavour.
- Type of coffee: Caffeine content can vary significantly between regular brewed coffee, espresso, instant coffee and decaffeinated coffee.
- Serving size: “One cup of coffee” can range from 30-700 ml (1-24 oz), which greatly affects the total caffeine content.
We will now show you the caffeine content of the different types of coffee we know.
It is the most common type of coffee in the United States and Europe. It is prepared by pouring hot or boiling water over ground coffee beans, usually contained in a filter. One cup of brewed coffee contains 95 mg of caffeine.
Espresso coffee is prepared by forcing a small amount of hot water, or steam, through finely ground coffee beans. Although espresso has arguably more caffeine by volume than brewed coffee, it tends to have a smaller portion. A shot of espresso is typically about 30-50 ml and contains about 63 mg of caffeine.
Many of the most popular coffee drinks are made with shots of espresso mixed with different types and amounts of milk. These include latte, cappuccino, macchiato and Americano.
As the milk contains no additional caffeine, these drinks contain the same amount of caffeine as pure espresso.
Instant coffee is made from brewed coffee that has been freeze-dried or spray-dried. It is usually in large, dry chunks, which are dissolved in water. To prepare instant coffee, simply mix one or two teaspoons of dried coffee with hot water. No brewing is necessary.
Instant coffee usually contains less caffeine than regular coffee, with one cup containing approximately 30-90 mg.
Although the name may be misleading, decaffeinated coffee is not entirely caffeine-free. It can contain varying amounts of caffeine, ranging from 0 to 7 mg per cup, with the average cup containing 3 mg.
However, some varieties may contain even higher amounts of caffeine, depending on the type of coffee, the decaffeination method and the size of the cup.
Finally, remember that according to FDA scientists, caffeine can be part of a healthy diet for most people, but too much caffeine can be a health hazard. Depending on factors such as body weight, medications taken and individual sensitivity, “too much” can vary from person to person.
