Could be the weather, but nothing sends our hearts aflutter like huge, bushy, Brooklyn beards. (Ginger ones!) So when we found out two brothers behind the scruff were making chocolate from scratch with their big, manly hands, we drooled all the way to their new factory/shop, Mast Brothers Chocolate, opening Saturday in Williamsburg (finally). Self-taught sibs Rick and Michael Mast (the only cocoa bean-to-bar chocolate makers in NYC) renovated a lofty old garage with rustic wooden counters, slick paneling, and a permanent choco scent. Bars of fleur de sel, dried cranberries, and “dark milk” will be poured without delay. Also on the menu are classes and wrapping parties with Mast’s signature patterned papers (one wrapped box equals one free glass of wine). Can’t wait to get your hands on ’em? Make that a sugar rush order. Mast Brothers Chocolate, 105 North Third Street, between Berry Street and Wythe Avenue, Williamsburg (718-388-2625 or mastbrotherschocolate.com). Open weekends, noon-6 p.m. Bloody hell, there’s more? Read NYC wrap-ups and London Fashion Week minutes on The Dossier (win gift bags, denim, and more stylish Swindles, too).
