Sourdough Starter

One of the oldest tools in bread making—and still one of the most powerful. For thousands of years, sourdough starter has been used to naturally leaven bread, relying on time, fermentation, and living cultures rather than commercial yeast.

This sourdough starter from Breadtopia contains naturally occurring wild yeast and friendly Lactobacillus bacteria, working together to create depth of flavor, structure, and digestibility. As the starter ferments, it brings a subtle tang and complexity to bread while supporting a slower, more intentional baking process—one that’s as much about patience as it is technique. It’s bread making in its most elemental form.

A living ingredient that connects modern kitchens to centuries of bakers before us—fed, tended, and shared, one loaf at a time.

Details: Naturally leavens bread using wild yeast and Lactobacillus bacteria. Adds complex flavor and supports digestion. Made with organic wheat flour and a wild yeast culture. A foundational ingredient for traditional sourdough baking.
