Izzio Artisan Bakery: America’s #1 Selling Sourdough Bread

Izzio Artisan Bakery is a family-owned Colorado bakery celebrated for its commitment to authenticity, quality, and ingredient transparency. Since 1994, Izzio has specialized in crafting traditional organic sourdough breads using a custom flour made from non-GMO wheat traced directly to local farms. Their signature flour is freshly milled, unenriched, and completely free from additives, offering a purely natural base for each loaf. The bakery employs small batch methods and extended fermentation, with some breads proofed for up to 72 hours. This time-honored process delivers superior flavor, texture, and digestibility, as long fermentation helps break down starches and gluten.

Izzio’s dedication to “baking as intended by Mother Nature” means they work only with whole, unprocessed foods and never compromise on quality—even in the face of customer demands for full transparency. Their partnerships with Colorado farmers and the local Provenance Mill ensure that every bread is flavorful, nutrient-rich, and fully traceable from seed to slice. Izzio’s artisanal loaves are enjoyed by customers nationwide, sharing not only great taste but also the company’s ethos of simple ingredients, tradition, and a passion for honest bread. The bakery stands as a leader in the next generation of authentic artisan baking, guided by integrity and a respect for nature.
