Bring the unmistakable flavor and texture of authentic San Francisco sourdough into your own kitchen with this heirloom‑variety starter culture. Carefully dried for stability and longevity, this living culture gives you the foundation to bake naturally leavened breads and a wide range of sourdough treats—using time‑tested methods that reward patience and care.

Each bag includes 1 packet of dehydrated starter culture that stores easily until you’re ready to begin. Activation is straightforward, using white flour and unchlorinated, unfluoridated water, and the culture thrives at typical room temperatures between 70° and 85° F. Clear instructions are included to guide you through the process, whether this is your first starter or a return to familiar practice. Once active, this is a truly reusable culture. With regular feeding, it becomes a continuous source of natural leavening you can maintain for years. Feed daily for frequent baking or weekly for a slower rhythm—whatever fits your household and schedule.

Made with high‑quality organic and non‑GMO ingredients, this versatile starter isn’t limited to bread alone. Use it for sourdough loaves, cookies, waffles, and other baked goods that bring depth of flavor and tradition back to everyday baking. It’s a small, practical step toward baking with intention and keeping old skills alive.
