Slow-fermented bread raised on wild yeast, dark-crusted and open-crumbed. San Luis Obispo's benchmark comes from Bread Bike, which mills California grain in-house and delivers by bicycle.

Sourdough is California's oldest food story, carried through Gold Rush camps and kept alive by the state's wild-yeast cultures. San Luis Obispo joined the modern grain revival when Bread Bike began milling California-grown wheat in-house on Parker Street, fermenting slowly and pedalling loaves to subscribers across town. The bakery's house-milled, long-fermented, naturally leavened loaves now set the city's bread standard, sold over the counter until they run out.
