Summer Sourdough Crushed Ice & Water Temp Chart for a Hot 82 Degree (82°F / 28°C) Kitchen — Spiral Mixer (76°F Artisan DDT)
4-factor Desired Dough Temperature (DDT) and 80 cal/g latent heat crushed-ice calculation for hitting 76°F dough in a hot 82°F room.
Four inputs decide the temperature of your water: the 76°F target dough, a 82°F room, 82°F flour, 82°F levain, and +18°F from spiral mixer (76°f artisan ddt). Solve 4 × 76°F − (82 + 82 + 82 + 18) and you land on 40°F (4.4°C) of mix water in this 82°F (27.8°C) kitchen. The faucet supplies 78°F and the dough needs 40°F, so ice is the only route: weigh 70g of crushed ice and 280g of 78°F water for the 350g batch, exploiting 80 cal per gram of phase change.

Baking Sourdough in a Hot 82°F Room: Why You Need 40°F Water (70g Ice)
The 76°F (24.4°C) target is a fermentation-speed decision, not a texture preference. A dough that lands at 40°F mix temperature in a 82 deg F (27.8°C) room will ferment at the rate the microbiology model assumes, and the 18°F friction allowance for spiral mixer (76°f artisan ddt) keeps the mixing heat from stealing that budget.
Mixing temperature is not dough temperature. The 18°F allowance for spiral mixer (76°f artisan ddt) assumes the heat is distributed through the mass rather than concentrated in the dough hook's path, so a slow first minute of mixing keeps the correction honest.
Thermal Control Protocol for Spiral Mixer (76°F Artisan DDT) in a 82°F Room
- Probe Ingredients (82 deg F / 27.8°C): Verify ambient room (82 deg F), flour, and starter temperatures with an instant-read probe thermometer before running Spiral Mixer (76°F Artisan DDT).
- Weigh 70g Ice + 280g Tap Water: For 350g total water, combine 70g finely crushed ice with 280g (@ 78°F) tap water.
- Verify Final 76°F Dough Temp: Probe the dough center immediately after spiral mixer (+18°F friction); it should read 76°F ± 1°F.
- Record the Reading: Write the actual temperature on your recipe card — in a 82 deg F (27.8°C) room the next bake will need the same correction, not a fresh guess.
Diagnostic Answers: What Water Temp for Sourdough in a 82°F (28°
Do I need crushed ice or is a cold fridge fine?
Crushed ice, always. Chilling the bowl in the refrigerator removes heat far too slowly for a 350g batch; the 80 cal/g latent heat of fusion in 70g of crushed ice does the job in under a minute.
How much ice do I add to 350g of bread water in a 82°F room (Spiral Mixer)?
Replace 70g of water with finely crushed ice and use 280g of 78°F tap water to hit 76°F DDT.
What is the DDT formula for a 82°F kitchen using Spiral Mixer (76°F Artisan DDT)?
Target water temperature = (4 × 76°F) − (82°F room + 82°F flour + 82°F levain + 18°F friction) = 40°F (4.4°C).
