Heritage and History
Mast Brothers Chocolate was founded in 2007 by brothers Rick and Michael Mast in Brooklyn, New York, helping to launch the American craft chocolate movement. The brothers began making chocolate in small batches in their apartment before opening a factory in Williamsburg, Brooklyn — one of the first American companies to produce bean-to-bar chocolate on a commercial scale in the twenty-first century.
The Mast Brothers factory became part of the story of Brooklyn's artisan food renaissance, attracting visitors and press coverage that helped build the American craft chocolate category.
Made in Brooklyn, New York
Mast Brothers produces all chocolate at its Brooklyn, New York factory, where the complete bean-to-bar process — roasting, winnowing, grinding, conching, and tempering — takes place under one roof. The single-origin approach means each bar's flavor profile reflects the specific terroir of the cacao farm rather than being blended for consistency.
For chocolate enthusiasts exploring the range of fine chocolate flavors, Mast Brothers' single-origin bars offer a structured way to experience how cacao from Madagascar, Peru, the Dominican Republic, and other origins differs in aroma, acidity, and flavor complexity. The elegant packaging design — hand-wrapped in distinctive patterned paper — makes Mast Brothers bars a premium gift as well as a fine eating chocolate.
