I enjoy anything dark, and like my dad (CDR-USN/Ret.) I like it strong enough to stand a fork up in it. Colombian is good. I really enjoyed the Black Silk, but I forget who made it...it's a grocery store item though, nothing "gourmet". Kona Blend is awesome.
But....thanks to my cardiologist (and my atrial flutter)...as of a year ago, I've had to completely drop caffeine, and booze. My 2 favorite food groups. So these days, I just try and find the least-offensive decaf so I can at least get the smell, and the activity, of a hot cup of something brown in the morning.
Somebody, have a good cup of Kona for me, okay?
