Allinson Very Strong White Bread Flour fermentation range
The catalog window for Allinson Very Strong White Bread Flour is 8–16 hours at 22°C (72°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.
