I rotate through the Ethiopian Harrar, Colombian Supremo, Guatemala, and Sumatra Mandheling, all decaffeinated, from Casteel Coffee in Evanston.
They taught me that their Mocha Java is a 50/50 blend of the Ethiopian and Sumatran - so I do that once in a while for variety. I tried their fair-trade Mexican decaf, but I just don't like it.
I've been a customer since the previous owner had a small shop on Davis street in Evanston - probably in the late 80's.
