Warm Water Temperature Chart for Sourdough in a Cold 70 Degree (70°F / 21°C) Kitchen — Spiral Mixer (76°F Artisan DDT)
Winter thermal compensation: using 76°F (24.4°C) mix water to overcome 70°F flour and hit a 76°F Desired Dough Temperature.
In a 70 degrees (21.1°C) kitchen (assuming flour and levain are also at 70 degrees) with Spiral Mixer (76°F Artisan DDT) (+18°F mechanical friction), the 4-factor DDT equation [4 × 76°F − (70 + 70 + 70 + 18)] requires a theoretical mix water temperature of 76°F (24.4°C). Simply adjust your tap water to 76°F (24.4°C) using all 350g liquid water (0g ice needed).

Crushed Ice & Tap Water Gram Table for 70°F Kitchen (Spiral Mixer (76°F Artisan DDT))
The 18°F friction allowance for spiral mixer (76°f artisan ddt) is already inside every target water temperature on this table.
| Recipe Water | Target Water Temp | Ice to Add | Water to Add (@ 66°F) | Dough Temp Achieved |
|---|---|---|---|---|
| [350g Ref]: 250g total water | mix at 76°F | no substitution | keep 250g warm water | friction +18°F absorbed |
| 100g Lighter: 400g total water | mix at 76°F | no substitution | keep 400g warm water | friction +18°F absorbed |
| 100g Heavier: 350g total water | mix at 76°F | no substitution | keep 350g warm water | friction +18°F absorbed |
| Half Batch: 300g total water | mix at 76°F | no substitution | keep 300g warm water | friction +18°F absorbed |
| Large Batch: 500g total water | mix at 76°F | no substitution | keep 500g warm water | friction +18°F absorbed |

Cold Kitchen Calorimetry: Why a 70°F Room Needs 76°F Mix Water (Spiral Mixer (76°F Artisan DDT))
Ice must be finely crushed. A 0g charge of coarse ice in a 70°F (21.1 Celsius) kitchen melts unevenly through the mix, and the last shards can shock the wild yeast even though the bulk of the dough ends up at the correct 76°F.
Ice quantity and water quantity are not interchangeable views of the same thing. 0g of crushed ice is the solid portion; the 350g of tap water that accompanies it is what actually hydrates the flour. Both numbers must be weighed.
Thermal Control Protocol for Spiral Mixer (76°F Artisan DDT) in a 70°F Room
- Account for the Friction First: Spiral Mixer (76°F Artisan DDT) adds +18°F, so subtract it from your target before you calculate the water temperature — that single step is what distinguishes a 76°F dough from a warm one.
- Solve the 4-Factor Equation: 4 × 76°F − (70 + 70 + 70 + 18) = 76°F of mix water for this 70 deg F (21.1°C) room.
- Execute the Water Adjustment: Temper all 350g of water to 76°F (24.4°C) and skip the ice entirely.
- Probe the Finished Dough: The reading should be 76°F ± 1°F; anything else means one of the three probed ingredients was off.
Key Baker's Math Questions (Required Water Temp: 76°F (24.4°C))
How much ice do I add to 350g of bread water in a 70°F room (Spiral Mixer (76°F Artisan DDT))?
No ice is needed — use 350g of liquid water tempered to 76°F (24.4°C).
Does the type of mixer actually change the water temperature?
Yes, and that is exactly what the friction factor models. Spiral Mixer (76°F Artisan DDT) contributes +18°F, so the same 70°F (21.1 Celsius) kitchen needs a 76°F mix water for this machine and a different one for a hand-mixed dough.
Why does my dough come out warmer than 76°F in a 70 deg F room?
Almost always the friction term. If you used 66°F tap water instead of 76°F, the 18°F that spiral mixer (76°f artisan ddt) generates has nowhere to go, and the finished dough overshoots the target.
