He absolutely paved the way for Barismo in many ways.
George Howell paved the way for much of the modern specialty coffee industry, Barismo included. I think that few people would argue that fact.
But it is neither here nor there. Brian was talking about the quality of the cup, something that George and Terroir often talk about. The proof, after all, is in the cup. While I am not a professional cupper, a decent roaster (those few roasts on a HotTop don't really count), or a professional barista, I agree with Brian about the quality of Barismo's coffees.
In the spirit of full disclosure, I'll admit that I am friends with most of the folks at Barismo (not because of any slander, but because of the consistently phenomenal coffee that I get as well as education that comes with it). Additionally, I know many of the owners of shops in the Boston area, but I am not (nor have I ever been) financially connected to any of the mentioned companies. I have also tried a variety of Terroir's coffees and been to their open house.
