IMPROVED PROCESS = Amazing Results! We have updated our process to create results that are better than ever. Your customers are going to love this! SHELF LIFE - Because our sourdough starter is freeze-dried, it is extremely shelf-stable. In ideal storage conditions, the actual shelf life is up to 25 years. However, to be conservative and ensure best quality for our customers, we officially state a 5-year shelf life. Enjoy sourdough the gluten-free way. Our gluten-free starter is cultivated using carefully selected gluten-free grains and pure water, nurtured until fully active, and then freeze-dried to preserve its strength and biodiversity. Once revived, it awakens into a vigorous culture that brings rise, flavor, and texture to your gluten-free baking—without compromise. Whether you’re newly gluten-free or a seasoned baker, this starter makes it simple to create homemade loaves that are wholesome, delicious, and unmistakably sourdough. Ingredients: Organic, Non GMO Brown Rice Flour, Mineralized Water.
