Caffeine and Coffee – two views

We had a series on coffee and I wanted to look more at that.

Drip Coffee or Espresso?

“A typical serving of drip coffee contains 95-200 mg of caffeine per eight ounce cup, and a standard serving of espresso contains 47-75 mg of caffeine per one ounce cup.”  So if you break it down to ounces a standard cup of coffee will have about 12 to 25 mg of caffeine. If you want the caffeinated buzz quickly, go for the expresso.

Types of beans

“Different beans have varying levels of caffeine content. For example, Ethiopian coffee is 1.13 percent caffeine, while Tanzanian coffee is 1.42 percent caffeine. The popular Arabica bean only contains 1.5 percent caffeine, while the strongest bean, the robusta bean, is 2.4 percent caffeine. Believe it or not, the color of the bean reveals information about its caffeine content. Darker beans require a longer roasting time, which means that more caffeine will burn off. Therefore if you are looking for a caffeine fix, stick with light beans.”

How are the beans are roasted can make a difference

“For the most caffeine per cup, buy finely ground coffee beans. Finer grinds have greater surface area for caffeine extraction. Additionally, brewing coffee between 195-205 degrees yields the best caffeine extraction. A longer brew time also results in a more caffeinated beverage, so stick with drip coffee instead of a French press.


An 8-oz, brewed coffee from Starbucks contains 180 mg of caffeine.
