Boudin Bakery's Claimed 1849 Sourdough Starter

Boudin Bakery at Fisherman's Wharf displays and uses a sourdough starter that the company says traces back to 1849 and has been continuously maintained through successive bakers. The bakery operates a public museum and displays explaining San Francisco sourdough's history and the starter's role in traditional San Francisco sourdough bread. The claim of an unbroken lineage to 1849 is made by the company and is commonly cited in accounts of the city's culinary history.
