Coffee and Caffeine FAQ

Another thing to consider is what kind of coffee you are drinking. Vietnam has recently become the worlds second largest coffee producer, and almost all of it is Robusta. The supply of cheap Robusta flooding the market has driven prices down and thus made its use more popular for some companies. (i.e. Folger's is about 33% Robusta)

Robusta beans can contain 2-4x as much caffeine as Arabacia beans. Selecting 100% Arabacia could be a good first step to lowering you caffeine intake.
