About

Grindstone Bakery is a California-based producer specializing in handmade, organic gluten-free sourdough breads crafted through stone grinding, fermentation, and baking. Since 1999, we focus on using simple, nutrient-rich ingredients like ancient grains, seeds, and fruits to create wholesome, flavorful loaves that preserve nutritional integrity and support health-conscious consumers. Our slow food process involves wild fermentation and small batch baking to develop complex flavors and tangy profiles. We package our breads in heat-sealed, eco-friendly packaging to extend shelf life, reduce waste, and maintain freshness. Our products serve retail, food service, and specialty markets seeking high-quality gluten-free baked goods with verified organic certification and a focus on sustainability.
