This Extra Sour Blend is a beginner-friendly combination of six organic flours, carefully crafted to build a strong, active sourdough starter with a bold, tangy flavor. Specifically designed to boost sourness, it’s ideal for those who prefer a deeper, more intense sour profile in their starter.


This blend can also be used for regular maintenance feedings. Consistent use helps maintain a stable microbial balance and may slow or reduce genetic drift in your starter over time.
