Sourdough Water Temperature Chart for a 76 Degree (76°F / 24°C) Kitchen — Spiral Mixer (74°F Artisan DDT)
4-factor Desired Dough Temperature (DDT) and mixer friction offset (+18°F) for hitting 74°F dough in a 76°F room.
A 76 degrees (24.4°C) kitchen demands careful water temperature discipline. With spiral mixer (74°f artisan ddt) generating +18°F and every ingredient starting at 76 degrees, the 4-factor DDT equation resolves to 50°F (10°C) for the mix water if you want a 74°F (23.3°C) final dough. Substituting 42g of the 350g with crushed ice and keeping 308g of 72°F liquid water lands the dough on 74°F, because melting ice absorbs 80 calories per gram.

Offsetting +18°F Mixer Friction in a 76°F (24°C) Kitchen: Target 50°F Water
The 4-factor equation is symmetric: a room that is 2°F cooler demands 2°F more from the water, and a mixer with 2°F less friction demands 2°F less. In this 76°F (24.4°C) kitchen the combined correction to 74°F is what produces the 50°F target, and the same correction scales proportionally with every additional gram of water.
Timing the correction is part of the correction. Weight the ice before the flour goes in, and mix ice and flour together first rather than adding ice to a wet dough, because the 80 cal/g latent heat only works if the ice is in contact with the water before the starch starts to hydrate.
Thermal Control Protocol for Spiral Mixer (74°F Artisan DDT) in a 76°F Room
- Account for the Friction First: Spiral Mixer adds +18°F, so subtract it from your target before you calculate the water temperature — that single step is what distinguishes a 74°F dough from a warm one.
- Solve the 4-Factor Equation: 4 × 74°F − (76 + 76 + 76 + 18) = 50°F of mix water for this 76°F (24.4°C) room.
- Execute the Ice Swap: Replace 42g of the 350g with finely crushed ice and keep 308g of 72°F tap water, melting the ice fully first.
- Probe the Finished Dough: The reading should be 74°F ± 1°F; anything else means one of the three probed ingredients was off.
Frequently Asked Questions for This Desired Dough Temp (DDT) & Ice Solver Spec
Does humidity in a 76°F (24.4°C) kitchen change the water temperature?
Marginally. On a humid morning the dough surface loses less moisture and cools a little less, so half a degree less cold water is usually right. Treat it as a refinement, not a correction.
How accurate is the 50°F figure in practice?
Within about 1°F, provided the four inputs really are 76°F room, 76°F flour, 76°F levain and +18°F friction. Probe the finished dough to confirm and adjust your next bake.
What happens if I use hot water from the kettle instead?
The dough lands above 74°F, the fermentation clock accelerates by roughly 4% per extra degree, and in a 24.4°C (24.4°C) kitchen the result is typically an over-fermented loaf that collapses in the oven.
