Desired Dough Temperature (Water Temperature) Calculator

Find the water temperature for your target dough temperature

Dough temperature controls how fast yeast and bacteria work, so it decides how long your bread takes to rise and how it tastes. Bakers fix it by changing the one ingredient they can control: the water. This desired dough temperature calculator tells you what temperature the water needs to be so that, after mixing, the dough lands on your target, allowing for the flour, the room, any preferment and the heat that mixing itself adds.

Enter your temperatures in °C or °F, choose how you mix and read the answer. If it says the water should be near freezing, an optional ice section works out how much of the recipe water to replace with ice. A short tool underneath helps you measure your own friction factor from a real batch. It all runs in your browser.

How to use the Desired Dough Temperature Calculator

1. Enter the desired dough temperature. Many bakers aim for 24 to 27 °C (75 to 80 °F).
2. Measure the flour and room temperatures with a probe or infrared thermometer.
3. Choose the mixing friction for your method, or type your own value. If you use a preferment, switch that on and enter its temperature.
4. Read the water temperature. If ice is suggested, replace that weight of the water with crushed ice.
5. Mix, measure the dough, and use the friction finder to improve the estimate next time.

The formula

After mixing, the dough temperature is roughly the average of the temperatures of everything that went in, plus the heat produced by kneading. With flour, room, water and friction, that average has three adjustable factors plus water, so water temperature = desired dough temperature × 3 − (flour + room + friction). A preferment adds a fourth term: water = desired × 4 − (flour + room + preferment + friction).

For example, a 24 °C target with 21 °C flour, a 22 °C room and 11 °C of friction gives 72 − (21 + 22 + 11) = 18 °C water. The page does the arithmetic in °C even if you work in °F, converting friction as a difference, so the answer is the same either way.

Friction factor: why you should measure it

Friction is how many degrees the dough warms from mixing. It depends on the machine, speed, mixing time, dough stiffness and batch size, so any preset is only a starting point. The presets here are about 5 °F for hand kneading, 20 °F for a stand mixer, 24 °F for a spiral mixer and 30 °F for a food processor. To find yours, bake a normal batch, measure the dough straight after mixing, and enter that with the water you used; the tool returns friction = dough temperature × 3 − (flour + room + water). Use that figure from then on.

Using ice

• When. In warm kitchens or in summer, the calculation often asks for water colder than the tap can give.
• How much. Ice at 0 °C absorbs heat as it melts. The tool uses ice = water × (tap − target) ÷ (tap + 80), with temperatures in °C.
• Mixing. Use crushed ice and give it time to melt into the dough; weigh it as part of the recipe water so hydration stays the same.
• Too cold. If even all-ice water is not enough, chill the flour, shorten the mix or use a cooler preferment.
