Pizza Dough Fermentation Time by Temperature Chart

Fermentation is a function of three things only: how much yeast, how warm the dough is, and how long you leave it. Fix any two and the third is decided, which is what makes a chart possible at all. Every figure here comes from the same model that runs the proof time calculator, so the chart on your fridge and the calculator on your phone will always agree.

What is the formula behind the chart?

Two lines of arithmetic. The first converts a temperature into a speed, and the second converts a yeast dose into an amount of work that has to be done at that speed.

• Rate at a temperature = 2 raised to the power of (temperature in F minus 75) divided by 17. At 75F the rate is 1.00, at 92F it is 2.00, at 58F it is 0.50 and at 39F it is 0.23.
• Fermentation needed = 4 hours multiplied by (0.30 divided by your yeast percentage), expressed as equivalent hours at 75F. A 0.15 percent dough needs 8 equivalent hours because there is half as much yeast doing the same job.
• Elapsed time = fermentation needed divided by the rate. Stages add: two hours at 70F contributes 2 multiplied by 0.82, or 1.6 equivalent hours, and the fridge covers the rest.

Worked through on the most quoted case: at 0.07 percent instant dry yeast the dough needs 4 multiplied by (0.30 divided by 0.07), which is 17.1 equivalent hours. In a 39F fridge running at 0.23 times the reference rate, that is 17.1 divided by 0.23, which is 74.4 hours. Three days, which is exactly why 0.05 to 0.08 percent is the standard dose for a 72 hour cold ferment.

How long will my dough take at my temperature?

This is the main chart. Find the dough temperature on the left, read across to your yeast dose, and the cell is the elapsed time from mixing to ready. The rate column tells you how the row compares to the 75F reference, which is useful when you need to convert part of a schedule rather than the whole of it.

Two things stand out. First, how fast the fridge column runs away: at 0.30 percent yeast a fridge dough is finished in 17.4 hours, well before the next evening, which is why cold ferment recipes call for less yeast rather than the same yeast and more patience. Second, how narrow the useful band is at the warm end. At 95F a 0.50 percent dough is ready in a little over an hour, and the window between ready and collapsed is measured in minutes rather than hours.

How much yeast do I need to hit a specific schedule?

Work the model backwards. Fix the elapsed time you want, work out how many equivalent hours at 75F that schedule delivers, then divide 1.2 by that figure to get the instant dry yeast percentage. The four columns below cover the schedules people actually run.

The first two columns are mostly a warning. Holding a dough at room temperature for 48 hours requires 0.025 percent yeast, which is 0.15 g on 600 g of flour, a quantity that is difficult to weigh accurately and leaves no margin for a warm afternoon. Long schedules belong in the fridge, where the low rate makes the timing forgiving rather than knife edge. Yeast percentages convert to grams on the baker’s percentage chart.

What do the standard two stage schedules look like?

Almost nobody puts dough straight into a fridge from the mixer. The usual pattern is a bench stage that gets fermentation started while the dough is still warm, then the fridge for the long haul. This table assumes 2 hours on the bench at 70F, which contributes 1.6 equivalent hours, followed by a 39F fridge.

Lengthen the bench stage and the fridge time falls sharply, because bench hours are worth three and a half times what fridge hours are worth. Three hours at 70F instead of two removes about three and a half hours from the fridge stage at any dose. That is a useful lever when a schedule is running late, and a dangerous one on a warm day when the kitchen is at 80F rather than the 70F you assumed. The method in full is in the cold fermentation guide.

Why is dough temperature not room temperature?

Because the yeast experiences the dough, not the air, and the two are rarely the same. Ten minutes in a stand mixer can leave a dough 10F above the room through friction alone, which halves every timing in the chart above. Water straight from a tap in summer and water from the same tap in winter can differ by 20F. A large batch holds its heat far longer than a single ball.

Professional bakeries solve this by calculating water temperature backwards from a target final dough temperature, usually 75 to 78F for pizza. The working rule is that water temperature should be roughly three times the target dough temperature, minus the flour temperature, minus the room temperature, minus a friction factor of about 10F for a stand mixer or 2F for hand mixing. If that sounds fussy for a home batch, the shortcut is simply to measure the dough after mixing with an instant read probe thermometer and adjust next time. An infrared gun cannot do this job, because it reads surfaces rather than the inside of a ball.

Fridges vary more than people expect too. A domestic fridge usually runs between 37F and 41F, and the door shelf can be 5F warmer than the back of the bottom shelf. Across a 72 hour schedule that difference is worth roughly 12 hours of fermentation, which is the gap between a dough that is ready and one that is still tight. Check yours once and then trust it.

What changes the model, and by how much?

The chart is a planning tool, not a law of nature. Four things move the real answer, and knowing the direction of each is more useful than pretending they do not exist.

None of that is a reason to skip the arithmetic. It is a reason to treat the number in the chart as the moment to start checking rather than the moment to stop. Read the dough as well as the clock: a ready ball has roughly doubled, holds a dome, and takes a fingertip dent that fills back slowly and not quite completely.

How do I read the rise instead of guessing at it?

Use containers with straight, clear sides so the dough shows you its own progress. A ball in a round mixing bowl under cling film gives you nothing to compare against, which is why pizzerias proof in graduated boxes. A set of latching dough boxes holds four to six balls with room to spread into discs, and stacks in a fridge, which is the practical difference between a cold ferment you actually run and one you keep meaning to try. For a bulk ferment before dividing, a graduated Cambro container turns "has it doubled" into a reading rather than an opinion. Options are compared in the dough proofing container roundup.

Take balls out of the fridge two to four hours before you plan to bake so they come up to around 65F. Cold gluten is stiff, and dough pulled straight from a 39F fridge springs back faster than you can open it. That warm up stage is not optional, and skipping it is the single most common reason a carefully planned three day dough refuses to stretch. Once the balls are ready, the ingredient weights are on the hydration calculator and the timing back on the proof time calculator.
