My current favorite is Don Pablo "Signature Blend" whole bean from Costco, really good.
Almost finished with my stash of gift coffees received last Christmas. The pound of Dunkin Donuts beans from my daughter is gone now, and there is about one or two grinder loads of the Bucamaranga beans from my sisters, both were quite enjoyable.
Costco's house brand, Kirkland, has 3-pound bags of whole beans from different regions around the world, Columbian, Guatemalan, Sumatran, Kona, etc. I was going to work my way through trying these out, but I'm a little gun shy after the bag of Guatemalan beans I tried had a distinctly burnt flavor to them. I see where some other folks here have had good experiences with these, so maybe I was just unlucky enough to happen upon a bad batch. I'd really like it if they'd put together some sort of sampler pack that had a quarter pound or so of each of them. Three pounds is an awful lot of something you haven't tried before.
