THE TOOLKIT / 04

Fermentation schedule & sourdough timeline

Plan your sourdough bake backward from target loaf to starter feed. Scales bulk rise with room temperature, schedules stretch & fold milestones, and coordinates overnight cold retarding.

YOUR STARTING POINTFREE TOOL / 04

Bulk fermentation scales inversely with ambient room temperature (~6 hrs at 21°C, ~3.5 hrs at 26°C). Milestones are reverse-engineered backward from target bake time.

Clock timeMilestoneAction & Details

Timeline milestones reverse-engineered backward to exact clock times.

A temperature-based sourdough fermentation and proofing schedule. Actual dough development depends on starter vitality, flour ash and protein, hydration and ambient stability. Observe dough dome, volume rise and aeration.

The formula

Bulk fermentation scales inversely with ambient room temperature: ~6 hrs at 21°C (70°F) to ~3.5 hrs at 26°C (78°F) at 20% starter inoculation. Milestones are reverse-engineered backward from target bake time.

Record the original values before changing them. Switching mass or length units converts the same physical quantities; changing a pan, yield or formula basis changes the project.
