Superior Taste & Organic Standards Our whole grain breads combine the highest nutritional and ecological standards with superior taste. We only use organic ingredients which is by definition non-gmo. Clean deep well water adds the final touch. Naturally Leavened & True Artisan Craftsmanship Our breads are leavened with a traditional sourdough culture, that has been allowed to ferment for 18 to 20 hours. This makes the bread easier to digest, the nutrients more bio-available and lowers the glycemic index. Making Organic Artisan Gluten Free Sourdough Breads with No Yeast Added.
