Sourdough Water Temperature Chart for a 76 Degree (76°F / 24°C) Kitchen — Stand Mixer Low Speed (75°F DDT)
4-factor Desired Dough Temperature (DDT) and mixer friction offset (+8°F) for hitting 75°F dough in a 76°F room.
Your mix water in a 76 deg F (24.4°C) room needs to sit at 64°F (17.8°C) to finish at 75°F, provided the flour, levain and room are all 76 deg F and stand mixer low speed (75°f ddt) contributes +8°F of mechanical heat. The arithmetic is 4 × 75°F − (76 + 76 + 76 + 8) = 64°F. Since the required 64°F sits below the 72°F coming from your tap, swap 15g of the 350g water for finely crushed ice — the 80 cal/g phase change does the cooling — and keep 335g of tap water alongside it.

Crushed Ice & Tap Water Gram Table for 76°F Kitchen (Stand Mixer Low Speed (75°F DDT))
Sums each row to the batch water weight so the split between ice and liquid always reconciles.

|---|---|---|---|---|
| Batch 250g [Primary] | target 64°F / 17.8°C | ice 11g | liquid 239g | lands on 75°F |
| Batch 400g Small Mix | target 64°F / 17.8°C | ice 17g | liquid 383g | lands on 75°F |
| Batch 350g Standard Mix | target 64°F / 17.8°C | ice 15g | liquid 335g | lands on 75°F |

Offsetting +8°F Mixer Friction in a 76°F (24°C) Kitchen: Target 64°F Water
Friction is the variable bakers forget. Stand Mixer Low Speed contributes +8°F, and because that heat is generated inside the dough rather than supplied from the room, it cannot be compensated by simply lowering the water temperature of the flour. It has to be subtracted from the mix water before mixing begins.
Friction factors are equipment-specific. The +8°F used for stand mixer low speed (75°f ddt) is a lumped parameter covering the steel bowl, ambient convection, hydration exotherm and shear work, and it changes if you switch from a spiral hook to a paddle.
Thermal Control Protocol for Stand Mixer Low Speed (75°F DDT) in a 76°F Room
- Start the Night Before: In a 76°F (24.4°C) kitchen the flour will sit near room temperature overnight if you store it sealed, so re-probe it in the morning rather than trusting yesterday's reading.
- Prepare the Water Station: Get the 64°F (17.8°C) water ready before you open the flour bag — once the flour is wet the temperature negotiation is over.
- Blend Ice and Water: Stir 15g of crushed ice into 335g of 72°F tap water until the slush is uniform, then pour over the flour.
- Record and Repeat: Note the final probe reading alongside the 76°F (24.4°C) room temperature so the next bake is a copy rather than a calculation.
Technical Q&A: Sourdough Water Temperature Chart for a 76 Degre
Should I probe the flour and levain separately?
Yes. The equation counts the flour and levain as 76°F each, and in a 24.4°C (76°F) kitchen a levain straight from the refrigerator can be 10°F cooler, which alone will miss the 75°F target.
Why is my crumb gummy even though the dough looked the right temperature?
A correct 75°F dough can still bake badly if the core never reached 208°F. Check the internal temperature with a probe rather than trusting the oven dial, and remember to cool the loaf for two hours before slicing.
How much ice do I add to 350g of bread water in a 76 deg F room (Stand Mixer Low Speed (75°F DDT))?
Replace 15g of water with finely crushed ice and use 335g of 72°F tap water to hit 75°F DDT.
