Name: Coffea charrieriana
Common Name: Charrier Coffee
How it made the Top 10: This is a new caffeine-free coffee from Cameroon, the first record of a caffeine-free species from Central Africa. Cameroon is a center of diversity for the genus Coffea and such wild species are potentially important in breeding programs. In this case the new species could be used for breeding of naturally decaffeinated beans.
