Dough temperature calculator
Work out the water temperature that lands your dough at its target after mixing. Enter your flour and room temperature; add a preferment for the four-factor version. °C or °F.
- Very cold or hot water? Adjust the room, or chill the flour, instead of shocking the yeast.
- Log how far off you land and tune the friction factor next bake.
Steering dough temperature with water
Every batch of dough starts from a few temperatures you cannot easily change — your flour, your kitchen, the heat your mixing adds — plus one you can: the water. The desired-dough-temperature method works backwards from the temperature you want to the water temperature that gets you there.
Three factors, or four with a preferment
For a straight dough, three things drive the final temperature: flour, room and friction. So water = DDT × 3 − flour − room − friction. When you add a preferment or a lively levain, that is a fourth temperature in the mix, so the multiplier becomes four: water = DDT × 4 − flour − room − preferment − friction. Toggle the preferment option above to switch between them.
Getting the friction factor right
Friction is the wild card — the heat your hands or your mixer add. It is small for a gentle hand mix and much larger for a long spell in a stand mixer. Start with a modest guess, measure your dough straight after mixing, and adjust: if you landed two degrees warm, your friction factor was two degrees higher than you assumed. A couple of bakes and you will know your own number.
Dough temperature FAQ
What is desired dough temperature (DDT)?
DDT is the temperature you want your dough to be right after mixing — usually 24–26 °C (75–78 °F) for sourdough. Hitting it makes fermentation predictable: too warm and the dough races ahead, too cool and it drags. You steer it mainly by adjusting the water temperature.
How do you calculate water temperature for dough?
Multiply your target dough temperature by the number of temperature factors, then subtract the others. With no preferment: water = DDT×3 − flour temp − room temp − friction. With a preferment or levain: water = DDT×4 − flour − room − preferment − friction.
What is the friction factor in dough?
Mixing adds heat through friction. For hand-mixing it is small — around 1–2 °C (2–4 °F). A stand mixer adds more, often 5–10 °C over a full mix. Start with a small value, then note how far off your actual dough temperature lands and adjust the friction factor next time.
Why is my dough temperature important?
Temperature is the throttle on fermentation. A dough at 27 °C ferments far faster than the same dough at 22 °C, so if you cannot control your dough temperature, your timings will never be repeatable. Nailing DDT is how bakers make the same loaf twice.
