Ever heard of Alpen Sierra? They’re a great coffee company located on the south shore of picturesque Lake Tahoe. I had opportunity a few years back to visit their store and was truly impressed. These people know about coffee.
They’re also one of the few places you can get 100% Kona coffee from Ka Hua O’Kona Farms, possibly the best coffee in the world.
Doing a little checking but I believe they offer green beans for roasting at home. I’ll keep you updated.
