•That iconic West Coast tang — the sourest loaf you can bake at home.
0 sold
A live San Francisco-style sourdough starter, hand-fed twice daily since 2018 and shipped at peak activity. Expect a bright, lactic tang and a toasted-grain finish. This is a 100% hydration culture — equal parts flour and water — that doubles reliably in about 4 hours at 76°F. It loves long cold retards, so it's the right jar for open-crumb country loaves, baguettes, and ciabatta. One ounce jar. Feed on arrival, then refrigerate between bakes.
