Triggered by Starter Peak
Cold ferment warning appears 45 minutes before predicted starter activity drop-off.
Starter peak timing is the most reliable natural signal to proceed. Once your starter has doubled, become bubbly, and begins to subside slightly around its 4- to 8-hour mark, it’s at peak strength. If your kitchen is cool, this peak may happen later than expected—around the 8- to 12-hour window—so the 45-minute heads-up gives you a chance to adjust before activity slows.
Cold temperatures slow microbial activity significantly. If your dough is in the fridge, the starter’s drop-off means acid production is slowing and gas generation is tapering. Starting bench time too late after this point may lead to under-proofing, because the dough won’t gain enough volume during bulk fermentation. Use the warning window to bring it to room temp or adjust your schedule.
This trigger assumes your starter was active at mixing and maintained between 20° to 25°C during feedings. For colder environments, extend feed intervals and monitor more closely. The warning helps you avoid guesswork: if the peak passed unnoticed, your first bake step may need compression or a brief warm rest to reinvigorate. Trust the rise—and act before it fades.
