The Story Behind It

The Tale of Sourdough Sandwich Loaf

Story updated September 18, 2026

Sourdough, leavened with wild yeast and bacteria cultures, is one of the oldest bread-making methods, predating commercial yeast by thousands of years. The sandwich-loaf format is a more modern adaptation, shaping the ancient fermentation method into a practical everyday bread.
