How to track bulk fermentation
A timer can remind you to check dough, but elapsed time by itself cannot tell you when bulk fermentation is complete. Dough temperature, starter activity, formula, and handling change the pace.
A repeatable check-in routine
- Record the flour, water, salt, starter amount, and starter condition.
- Measure dough temperature after mixing. Room temperature is useful context, but dough temperature is more direct.
- Mark the dough level in a straight-sided container, or use a small aliquot sample so expansion is easier to compare.
- At regular intervals, note expansion, bubbles, surface shape, elasticity, and whether the dough moves with a gentle jiggle.
- Use the recipe’s shaping cues and your observations together. Do not treat a single rise percentage as universal across recipes and containers.
Keep a small log
| Time | Dough temp | Rise / bubbles | Texture / note |
|---|---|---|---|
| Mix | Record | Observe | Write what changed |
| Check 1 | Record | Observe | Write what changed |
| Check 2 | Record | Observe | Write what changed |
| Shaping decision | Record | Observe | Write what changed |
After a few bakes, compare similar formulas rather than trying to make one timing rule fit every dough.
What can shift the schedule?
Starter amount and maturity, desired dough temperature, flour, salt, dough hydration, folds, and holding temperature all interact. King Arthur Baking’s bulk fermentation guide discusses recipe, temperature, and dough cues; use it as context alongside the formula you are following.
The sourdough calculator provides a broad planning estimate. Read the methodology and limits before using it as a schedule.
