CoralDepth · Accepted Answer

Bread dough yeast bubbles. Bread Dough Yeast Bubbles When yeast ferments dough, it's actually producing carbon dioxide and alcohol—the alcohol evaporates during baking, but some of it contributes to bread's aroma and flavor before it disappears. This means every loaf of bread is technically the result of a tiny, controlled fermentation process similar to what happens when making beer or wine, just at a much smaller scale and shorter timeframe.
