Overview
A 12-gram freeze-dried San Francisco-style sourdough starter made from organic, non-GMO flour, positioned to activate quickly and double in size within about an hour once it is fed and running.
Like the Living Dough listing in this same category, the sell here is San Francisco heritage flavor, but the format is freeze-dried rather than fresh, so it needs rehydration before the first feed.
- 12g freeze-dried starter, organic non-GMO flour
- San Francisco heritage sourdough flavor profile
- Listing states doubling in about an hour once active
- Works across bread, pancakes, waffles, muffins and pizza
Who it's for
Fits bakers who want a San Francisco-style tang and are comfortable rehydrating and maintaining a starter afterward. Less suited to anyone wanting a ready-to-use fresh culture with zero setup, since freeze-dried formats need an activation period first.
Pros and cons
- Freeze-dried for a longer shelf life before you start it
- San Francisco-style culture for a tangier, traditional flavor
- Organic, non-GMO flour with no additives per the listing
- Meant to be fed and reused indefinitely once active
- Needs an activation period before first use, unlike a fresh live starter
Performance notes
Being freeze-dried rather than fresh, the culture needs to be rehydrated and fed before it behaves like an established starter, and the listing states it should be bubbling within days of that first feed, doubling in about an hour once active. As with any wild yeast culture, the exact speed and flavor settle in over several feedings as it adapts to local flour and water.

Frequently asked questions
Is this starter ready to use right out of the package?
No, it is freeze-dried, so it needs rehydrating and feeding before it behaves like an active starter.
How fast does it grow once active?
The listing states it doubles in size within about an hour once it is up and running.
What gives it the San Francisco flavor?
It is cultured from a traditional San Francisco-style sourdough formula, which the listing ties to a more tangy, bold flavor than a generic starter.
