Dough Temperature and Fermentation
In sourdough baking, temperature should be treated as an ingredient. Every loaf you bake is shaped by how warm or cool your dough is the moment you finish mixing. It sets the pace for everything that follows such as how fast your dough rises and how much flavor develops. Two bakers can use the same recipe and end up with two different loaves, simply because one dough was a few degrees warmer than the other.
The good news: you don’t have to guess. Plug your numbers into the calculator below to find the right mixing water temperature before you start, then check back in after mixing to see where you landed — and what to do next.

Dough Temperature Calculator
Find the right water temperature before you mix, then check your dough after — and know what to expect from your rise.
Typical sourdough DDT range is 75–82°F (24–28°C). If you're building with a levain or ripe starter, add its temperature here for a more accurate result. Using commercial yeast instead? Leave this field blank.
Heat added by mixing. Leave at 0 for hand-mixed dough. Stand mixers typically run 20–40°F (11–22°C) depending on speed and mixing time — if you don't know yours, start at 0 and adjust next time based on your actual dough temp.

Fixing dough that’s off target
If it’s too warm:
• Move the covered dough into the fridge for 15–30 minutes, then check its temperature and pull it once it’s cooled enough (about 76-78°F).
• Or, simply shorten bulk fermentation and move to shaping a little earlier than planned.
If it came out too cool:
• Give it a warm, enclosed spot, like in the oven with the light on, or a proofer. Stay mindful not to push past about 85°F.
• Or, simply let bulk fermentation run longer and shape later than planned.
