In 1849, Isidore Boudin combined his skill of French bread baking with fermented wild yeast nurtured by the fog-cooled air. This magical combination created The Original San Francisco Sourdough™ – Boudin. The bread with its dark golden crust, soft, chewy center, and distinctive flavor soon became a local favorite. We are San Francisco’s oldest continuously operating business. Much has changed since our boomtown beginnings, but one thing hasn’t: our commitment to honor and preserve the art and science of The Original San Francisco Sourdough™
