Waitrose Italian 00 fermentation range
The catalog window for Waitrose Italian 00 is 24–48 hours at 4°C (39°F). Pandough estimates yeast and timing from that window plus your hydration, salt, yeast type, and the temperatures the dough actually sees.
Fermentation time also depends on dough temperature, yeast amount, hydration, and the split between warm and cold proofing.
