I’ve always thought that the darker the roast and bolder the brew, the more caffeine there is in a cup of coffee. But a friend just told me that it’s the lighter roasts that have the most kick. Is this true?

Yes, though different species (Arabica vs. Robusta) and varietals (Bourbon, Typica, Caturra, etc.) can have different caffeine content, and the way the coffee is brewed can also change the values. For instance, a “typical” 8 oz. cup of brewed coffee contains on average between 60 – 100 mg caffeine, compared to 45 – 100 mg of caffeine in a 2 oz. double espresso.

Robusta coffee, an overall inferior, bitter-tasting species of coffee widely used in inexpensive mass market blends, instant coffee and some espressos, contain about twice as much caffeine as do Arabica coffees.

All of our Bold Bean coffees are 100% Arabica.

Among Arabica coffees, however, the differences in caffeine are slight. The roasting process reduces the amount of caffeine, but the amounts are actually minimal. If you’re wanting more caffeine, have another cup. If you’re looking to reduce your caffeine, a dark roast isn’t the answer. Go with a decaf (which, by the way, still contain a small amount of caffeine).
