I'm reviving this thread because I have become a fan of
George Howell coffee. He has a very wide-ranging selection. Although the coffees are expensive (some VERY EXPENSIVE), the quality is outstanding. In particular, I like the Tarrazu, Daterra, and Matalapa varieties. I have not, by any means, tried all his offerings, but I have been impressed by everything that I have bought.
I first became acquainted with Howell while visiting The Coffee Connection, his now-defunct outlet in Cambridge, MA. Alas, that emporium went out of existence when George sold it to Starbucks (a travesty, IMHO). Coffee lovers should give it a try.
