Real San Francisco Sourdough

Sour Flour bakes classic San Francisco sourdough bread, bagels, and pretzels out of La Victoria Bakery in the Mission. We deliver fresh bread every morning around the Bay Area and hold classes and workshops. We strive to nourish our community, teach the art and science of bread baking, and empower bakers with knowledge and skill.
