Dough warmer or colder than the recipe? Get the adjusted proof time — and the exact water temperature for consistent fermentation.
Model: fermentation roughly doubles every ~10°C (Q10≈2). A real-world estimate, not a guarantee — dough, yeast amount and flour vary.
Warmer dough ferments faster, colder dough slower. As a rule of thumb fermentation rate roughly doubles for every ~10°C increase, so a 6°C drop can nearly double your proof time.
DDT is the dough temp you want after mixing. Bakers hit it by adjusting the water temperature, since flour and room temp are mostly fixed. Water temp = (DDT × 3) − flour − room − friction (hand mixing has little friction).
