How Much Yeast Do I Need
for Pizza Dough?
Quick Answer
For a 24-hour pizza dough at room temperature (22°C), use 0.1% instant dry yeast—that's approximately 0.6g for 4 pizzas (610g flour total). For same-day dough (6-8 hours), use 0.5% (about 3g).
Why Yeast Amount Varies
Yeast is a living organism that multiplies and produces CO₂ gas. The amount you need depends on just two factors.
1. Fermentation Time
Longer fermentation = less yeast. With more time, fewer yeast cells can do the same work while developing better flavor.
2. Temperature
Warmer = faster yeast activity. At 25°C, yeast works nearly twice as fast as at 20°C. Cold (4°C) slows it by 90%.
Reference Table (Room Temperature)
Use this table for room temperature fermentation. Percentages are relative to total flour weight (Baker's Percentage).
| Time | 20°C (68°F) | 25°C (77°F) | 30°C (86°F) | Grams* |
|---|---|---|---|---|
| 4 hours | 1.50% | 1.00% | 0.70% | 9.15g |
| 6 hours | 0.80% | 0.50% | 0.35% | 4.88g |
| 8 hours | 0.50% | 0.30% | 0.20% | 3.05g |
| 12 hours | 0.25% | 0.15% | 0.10% | 1.52g |
| 24 hours | 0.10% | 0.05% | 0.03% | 0.61g |
| 48 hours | 0.04% | 0.02% | — | 0.24g |
| 72 hours | 0.02% | — | — | 0.12g |
Note: These are starting points. Factors like flour strength, humidity, and yeast freshness affect results. Always watch your dough, not just the clock.
Cold Fermentation (The Pro Method)
Cold fermentation (in the fridge at 4°C/39°F) develops superior flavor. Start with 2 hours at room temperature, then refrigerate.
| Total Time | Yeast % | Grams* | Method |
|---|---|---|---|
| 24 hours | 0.15% | 0.91g | 2h room temp + 22h fridge |
| 48 hours | 0.08% | 0.49g | 2h room temp + 46h fridge |
| 72 hours | 0.05% | 0.30g | 2h room temp + 70h fridge |
Common Questions
The amount depends on fermentation time and temperature. For a standard 24-hour cold ferment, use 0.1-0.15% instant dry yeast (0.6-0.9g for 610g flour). For same-day 6-hour dough at room temperature, use 0.5-0.8% (3-5g). Use our table below for exact amounts.
