Taza Chocolate in Somerville Ma.
5 years ago Alex Whitmore and partners Larry Slotnick and Kathleen Fulton (also Alex's wife) started this mesoamerican-style bean-to-bar chocolate factory. And true to their vision, this chocolate is handmade from start to finish. They buy their beans in the DR, Mexico, Belize, and they recently added Bolivia. (note: if you get a chance, try the 87% bolivian choc bar side by side with the 80% DR...then you'll really see what terroir means to the cacao bean.)
Their beans are fermented, which means, like all things fermented, flavor is amped. And then they get roasted (in the fabulous Willi Wonka machine pictured below. don't you want one? I do. and it's RED!) The beans are then stone ground, on mexican stone mills that Alex hand chisels himself (check out the pic below of him holding one.) Impressive.
