Fermentation

Fermentation is where dough becomes expressive. Yeast produces gas, enzymes unlock sugars, acids build flavor, and gluten relaxes enough to stretch without fighting back.

The main variables

Time and temperature do most of the work. Warmer dough ferments faster and can move from ready to overproofed quickly. Cooler dough ferments more slowly, giving flavor and structure more time to develop.

Yeast amount controls the pace, not the quality by itself. Less yeast with more time often gives better flavor and handling than more yeast with a rushed schedule.

Preferments and cold dough

Poolish, biga, levain, and cold fermentation are all ways to manage time. They are useful when they solve a real problem: better flavor, easier scheduling, or a dough that stretches with less force.

Good fermentation is practical. The goal is dough that is relaxed, lively, and ready when your oven is ready.
