San Francisco

San Francisco is a place in this atlas, not a brand. It is where Tartine Bakery bakes on Guerrero Street, where Ferry Building gathers merchants at the foot of Market Street ¹, and where sourdough became a civic story — argued on San Francisco sourdough, embodied commercially at Boudin Bakery, and baked cooperatively in the Inner Sunset at Arizmendi Bakery (9th Avenue).

The city eats what it does not grow. Marin County dairies and Napa Valley vineyards are the hinterland. Flour often arrives from plants just over the county line — Giusto's Vita-Grain in South San Francisco is one mill-and-processor node. Cowgirl Creamery belongs to that wider Bay Area more than to a current city shop. This page is a hub, not a complete gazetteer.
