Type of Coffee Matters
The type of coffee in your cup matters because how the beans are prepared affects the caffeine content. Decaf, instant, brewed, and espresso are the most popular types to consider.
Decaffeinated coffee is not entirely caffeine-free. However, the amount of caffeine varies depending on the kind of beans and the method of decaffeination used.
Instant coffee is a spray-dried or freeze-dried form of brewed coffee that dissolves easily in water. As a result, the caffeine content is usually less than in regular brewed coffee.
Regular brewed coffee is made by using a filter to run boiling hot water over ground beans. Its caffeine content is more than decaf and about the same as espresso.
The method used to make espresso involves using pressurized water or steam with finely ground beans. As a result, espresso’s caffeine content maybe a little more than regular brewed coffee or about the same.
Caffeine Content Of Your Beans
The type of beans used to make your morning java influences how much kick you will get from your cup. The two most produced beans in the world are Arabica and Robusta, and their caffeine content is far from similar. You might also be interested in learning if espresso loses caffeine over time.
Arabica coffee beans contain about 34.1 to 38.5 grams of caffeine per kilogram.
Robusta coffee beans contain about 68.6 to 81.6 grams of caffeine per kilogram.
Caffeine And Roasting Methods
Lighter roasts have greater caffeine content than darker roasts when compared by weight instead of volume. However, the difference in caffeine content varies between batches, so that the averages are not overwhelmingly significant but can still add up when considered with the other caffeine content factors.
Cup Size Matters
