Description
Sourdough starter maintenance involves feeding schedules, hydration ratios, and temperature control to balance yeast and lactobacilli activity for optimal leavening and flavor.
Technical
During fermentation, wild yeast Saccharomyces cerevisiae converts sugars into CO₂ and ethanol, while lactobacilli produce lactic and acetic acids. The interplay of these microbes, governed by pH, temperature, and hydration, determines the starter’s acidity, rise, and flavor profile.
