What is this?
Proofing time (Gärzeit) is the duration a dough spends fermenting (bulk or final proof) where temperature controls the biochemical rate of fermentation. Higher temperatures accelerate yeast and bacterial activity, lower temperatures slow it. Planning proofing by temperature helps hit the desired dough maturity predictably [1][2].
Why important: Correct proofing time affects dough strength, oven spring, crumb structure, acidity development and flavor balance. Mistimed proofs cause underproofed tight crumb or overproofed weak structure and loss of oven spring [1][2].
Calculator
Uses Q10 temperature coefficient. For Q10=2 each 10°C change halves/doubles rate [1][2].
These are practical guidance rules-of-thumb based on fermentation kinetics [1][2].

Hydration Ranges
Slow fermentation, extended proofing (many hours to days), more lactic acidity and complex flavor
Balanced speed and flavor development, good for predictable schedules
Fast fermentation, less acid development, higher risk of overproofing
Tips
💡 Measure dough temperature, not room air
Dough temperature is what drives fermentation. Measure with an instant-read thermometer inserted into the dough mass for accurate adjustment calculations [1].
💡 Include starter water in calculations
Water already present in your preferment/starter contributes to dough temperature and total water—account for it when planning fermentation and using the calculator [1][2].
💡 Use predictable equipment
A consistent container and method (e.g., large mixing bowl shape and covering) reduces variables so the calculator's estimate matches reality [1].
💡 Adjust using dough behavior
The calculator gives a timetable; always confirm with dough cues (volume, gluten development, feel). Time is a guide, not a substitute for observation [1][2].
💡 When in doubt, cool it
If your adjusted time is much shorter than planned, place dough in the fridge to slow fermentation and retain structure—this aids schedule control and flavor [2].
