I have a life-long friend that I've known since we were in middle school (back in the early 1980's) that is a World Cupping Judge and a green coffee buyer for Caribou Coffee and their coffee is good. I have been brewing Starbucks Reserve Kona and Kenya roasts. I grind the whole beans just before roasting. I use a brilliant Moccamaster brewer. I prefer medium or dark roasts. A just picked up a Mayan roast grown by a co-op of small farms that I'm excited to try.
