QUESTION:


Am I over caffeinated? I have no idea. But I would like to know. So can you tell me how much caffeine there is in a cup of coffee? Please?

ANSWER:

Frank, hi. Thanks for the question.

Let’s start with the amount of caffeine in an average, 7-ounce cup of regular coffee.

As you’ll see below, the caffeine per cup is going to depend on three factors – the way in which you brew your coffee, where the coffee was grown, and how it was roasted.

Here goes...

Caffeine levels according to the brewing method.

Drip Coffee 115-175mg

Espresso - 1 serving (1.5-2oz) 100mg

Brewed 80-135mg

Instant 65-100mg

Decaf, brewed 3-4mg

Decaf, instant 2-3mg

The caffeine in coffees from different parts of the world.

These figures represent the percentage of caffeine in the bean.

Caffeine percentage according to the roast of the bean.
