John Scharffenberger, already a big name in the wine world, decided in 1997 to try his hand at artisanal chocolate-making. Using a vintage German melangeur — a machine that slowly grinds cacao beans into a chocolate liquor — and personally sampling beans from more than 150 international cacao farms. Now a member of the Hershey family, Scharffen Berger produces a modest but exquisite selection of bars and tasting squares sold at stores like Whole Foods including a crunchy Milk Chocolate Bar with Sea Salted Almonds.
