The coffee guys in the next forum down might be able to help you out here. Although I know some of us bleed over into that forum as well.
I glanced over there, started reading on different beans from different farms, different roasters.....and slowly backed out! I can't handle more than one slope at a time.
You double slopers, you have my admiration, and my pity!
Let us know what you come up with, as I am a coffee drinker as well.
