Mother Cultures Heirloom Sourdough Starter

Fermentation, Elevated.

Bread is more than food; its tradition, community, and nourishment. Our Organic Heirloom Sourdough Starter helps you carry that legacy forward.  

Unlike commercial yeast, which works flat but fast, our living culture is a slow fermenter - cultivating rich layers of flavor, a beautiful rise, and crust that sings when you pull it out of the oven. With every feeding, your starter strengthens, becoming a baking companion for life. 

From rustic boules and country loaves to pizza dough, bagels, and pastries, this is the foundation of real bread. Wholesome, resilient, alive.
