The caffeine content of coffee depends on a few factors: type of bean, degree of roasting and method of grinding and brewing. (Caffeine content is measured in milligrams per cup. A moderate caffeine intake is 250-300 mg per day. An average cup of coffee ranges from 80 to 150 mg per cup.)

• Type: Arabica beans have about half the caffeine of Robusta beans. (We use only Arabica beans.)
• Degree of roasting: Roasted Arabica has about a 1.4% caffeine content. Darker roasts do not have more caffeine than lighter roasts—that’s a misconception.
• Method of grinding and brewing: The finer coffee is ground, and the longer it’s brewed, the more caffeine can be released. The amount of ground coffee one uses per cup also effects the level of caffeine. 

Concerned about caffeine? Try decaf: it has only about 2 mg of caffeine per cup. Or, mix decaf with regular coffee to lower the caffeine.
