Taste the Difference of Real Sourdough™
At izzio, we craft our bread in small batches with simple ingredients. Each loaf begins with a naturally fermented sourdough starter – the foundation to create the most delicious, digestible, and wholesome breads. As a family-owned Colorado bakery, we’ve collaborated with farmers and millers to create a custom flour that is 100% traceable to the mill and free from enrichments or additives. From classic artisan boules and batards to sandwich-ready loaves or our delicious sourdough baguettes, every bite reflects over a decade of baking expertise and our passion for quality. Taste the difference of real sourdough with izzio™.
Three Main Ingredients
Every loaf of izzio sourdough starts with just three main ingredients: flour, water and salt. And our final ingredient: time. We don’t rely on baker’s shortcuts like vital wheat gluten or vinegar to create the texture and tang of a true sourdough. At izzio, we make real sourdough – and only real sourdough.
Ancient Baking Techniques
We make bread the way it was crafted thousands of years ago. While many commercial breads rely on preservatives like calcium propionate or vital wheat gluten, we let our bread ferment slowly and naturally, giving every loaf the time it needs to become what it was meant to be: a balance of unmatched flavor and texture, along with our sourdough’s signature open crumb and golden crust.
Small Batch Baked
There’s something special that happens when bread is baked in small batches. It’s cared for, not produced. izzio is a family-owned Colorado bakery that utilizes time, tradition, and trained hands to bake our bread.
Slow Fermentation
Every izzio loaf begins with a naturally fermented sourdough starter. Long fermentation breaks down starches and gluten, which lowers the bread’s glycemic index (reducing blood sugar spikes) and may make it easier to digest. In addition, fermentation produces acetic acid, which preserves the bread and extends shelf life – naturally! The result is delicious, more digestible bread that your body recognizes, and your taste buds crave.
High Quality Ingredients
We offer Non-GMO Project Verified and USDA Organic breads. You can enjoy peace of mind that every loaf is free from preservatives, artificial flavors, seed oils, and vital wheat gluten.
Freshly Milled Flour
Our custom flour is traceable to the mill and unenriched to capture the natural vitality of the grain at its peak, delivering a vibrant, complex flavor.

Signs of Real Sourdough
- Just 3 main ingredients: flour, water, and salt
- Mentions of “sourdough starter” or “culture” in ingredient list

Red Flags for “SourFaux”

- Added vinegar, lactic acid, or “sourdough flavoring”
- Long lists of additives such as:
- Dough conditioners like vital wheat gluten or potassium bromate; low-quality seed oils
- Added preservatives
- Long expiration dates
- Real sourdough naturally resists mold longer than yeasted bread, however it’s rarely weeks and weeks like most commercial breads
- Mass production methods and/or lower grade ingredients
