How much yeast does pizza dough need?

Yeast quantity is the most over-done ingredient in home pizza. Packet recipes call for a whole 7 g sachet because they want a fast, foolproof rise — but fast is the enemy of flavour, and a blast of yeast gives you bready, one-note dough.

Yeast and time trade off directly

Think of it as a dial: more yeast = faster rise; less yeast = slower rise. They're two ways to reach the same risen dough. Since slow fermentation tastes better, the skilled move is to use less yeast and give it more time.

• Same-day (4–8 h): around 0.3–0.5% instant dry yeast
• Overnight room temp (10–14 h): around 0.1–0.2%
• Cold ferment (24–72 h): as little as 0.05–0.1%

The temperature catch

Those numbers assume a normal kitchen. In a warm room the same dose ferments faster, so you'd use even less; in a cool room, a touch more. This is exactly the adjustment Doughborough makes automatically — you give it the temperature, it adjusts the timing and yeast dose around it.

A note on yeast types

Instant dry, active dry and fresh yeast aren't interchangeable gram-for-gram. Active dry is roughly 25% weaker than instant and wants rehydrating first; fresh yeast is about a third the strength. The calculator converts between them for you.
