Sourdough starter maintenance involves feeding schedules, hydration ratios, and temperature control to balance yeast and lactobacilli activity for optimal leavening and flavor.
Origin: French, San Francisco, Italian, Asian (Traditional to contemporary) — Europe, North America, Asia
See full technique reference →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.
Primary Reaction
Fermentation of carbohydrates to CO₂, ethanol, lactic acid, and acetic acid
