What to know

The inside local's take

1

The signature tang comes from Lactobacillus sanfranciscensis — a wild bacterium that thrives specifically in the coastal fog microclimate of the Bay Area.

2

Boudin's Fisherman's Wharf bakery has a glass-walled viewing gallery where you can watch bakers hand-shape hundreds of loaves a day.

3

For a modern take, Tartine on Guerrero in the Mission bakes their country loaf twice a day — cash-only line, worth every minute.
