Controllable factors that influence the caffeine content of a cup of coffee include how finely ground the beans are before brewing and the method and length of brewing time. the drip method, using finely ground beans, yields the highest amount of caffeine because the water is in contact with the grounds for the longest amount of time.
Back in ’79, Bunker and McWilliams published a paper after studying the caffeine content of common beverages. Here are their coffee-based findings (caffeine content noted in mg):
* Espresso: 1 cup (1.5–2 oz, 45–60 ml) = 100 mg.
* Brewed: 1 cup (7 oz, 207 ml) = 80–135 mg. (107.5 mg. average)
* Drip: 1 cup (7 oz, 207 ml) = 115–175 mg. (145 mg. average)
and instant coffee generally yields the least amount of caffeine, about 65mg per cup.
