Coffee that is naturally Caffeine-free.
Charrier Coffee. or Coffea charrieriana, is a “new caffeine-free coffee from Cameroon, the first record of a caffeine-free species from central Africa…In this case the new species could be used for breeding of naturally decaffeinated beans,” according to Arizona State University’s International Institute for Species Exploration (ASU)
Maybe in another 10 years, it will be commercially available.
Till then, good quality arabica beans are still the coffee with the lowest amount of caffeine.
