What You Need to Know
During fermentation, lactic acid bacteria convert sugars to lactic and acetic acids, lowering pH and strengthening the gluten network, while wild yeasts produce CO₂ that leavens the dough. Baking gelatinizes starches, denatures proteins, and initiates Maillard reactions, giving the crust its color and the crumb its characteristic texture.
