I was actually trying to figure that out but don't think they list their blends, I could pry contact them but figured ehhh oh well lets see how it is lol. Mocha Java is almost always some type of blend of African and Indonesia beans, generally Ethiopian and Sumatra/Yeman.
That surprises me, as most companies list the various beans - and their location, and sometimes, their altitude along with actual bean varietal - that go into a blend either on the packet, or on their website.
Anyway, I shall await your comments as to origin with interest; even more interest will be reserved for your (eventual) tasting notes. Enjoy!
