Desired dough temperature calculator
Water is the only temperature in the bowl you can easily control. This works out how warm or cold it should be so the dough finishes mixing exactly where the recipe wants it.
Use water at
31.0 °C
25 × 4 − 21 − 22 − 24 − 2 = 31.0
A temperature budget, step by step
The DDT method treats every ingredient’s temperature as a share of one total. Step through a real example.
Start with the target
You want the dough at 25 °C when mixing ends. With a levain in the mix there are four heat sources, so the combined budget is 25 × 4 = 100.
Why dough temperature matters
Yeast and sourdough bacteria roughly double their activity with every 8–10 °C rise in the range bakers use. A dough that comes off the mixer at 22 °C instead of 26 °C can take an hour or more longer to ferment. Professional formulas, including those taught in Jeffrey Hamelman’s Bread and by the San Francisco Baking Institute, specify a DDT so that timings in the recipe actually hold in your kitchen.
Measure flour temperature with a probe thermometer pushed into the bag. For levain timing, see the starter ratio calculator.
Questions bakers ask
What is desired dough temperature (DDT)?
The temperature you want the dough to be when mixing ends, usually 24–26 °C (75–78 °F) for bread. Hitting it makes fermentation times predictable, which is why professional recipes list a DDT.
How do you calculate water temperature for bread?
Multiply the DDT by the number of temperature factors (3 for a straight yeast dough: flour, room, friction; 4 when a preferment or levain is added). Subtract the known temperatures. What is left is the water temperature.
What is friction factor?
The heat added by mixing. It depends on the mixer and mixing time: roughly 0–3 °C (1–5 °F) by hand, 7–12 °C (13–22 °F) in a stand mixer, and higher in a spiral or intensive mixer. Measure it once: mix a dough, check its temperature and back-calculate.
What if the water needs to be below freezing?
Use ice. Weigh the ice as part of the water, and since melting ice absorbs a lot of heat, use roughly one part ice to three parts cold water to cool a dough substantially. Or chill the flour overnight.
