Sourdough Starter Trend 2026

A living culture of wild yeast and beneficial bacteria, a sourdough starter is the natural leavening agent behind artisan bread. By fermenting flour and water, it creates rise and that signature tangy flavor. Bakers use it to replace commercial yeast, producing digestible, complex loaves. Home bakers, health enthusiasts, and sourdough artisans benefit from its rustic texture and deeper nutritional profile.
