Cold fermentation

Cold fermentation means letting shaped or bulk pizza dough rise slowly in the refrigerator instead of at room temperature, typically for one to three days. The cold slows yeast activity way down without stopping it, so the dough keeps developing over a much longer window than a same day dough would allow.

That slow pace changes both flavor and texture. A longer, cooler fermentation gives yeast and enzymes more time to break down starches into simpler sugars and build more complex flavor, and it also relaxes the gluten network so the dough becomes noticeably more extensible and easier to stretch thin without springing back or tearing.

Dough should be kept in a covered, airtight container during cold fermentation so the surface does not dry out and form a skin, and it needs time to warm back up on the counter before shaping since cold, stiff dough tears easily. A common mistake is pulling dough straight from the fridge and trying to stretch it immediately, or letting it ferment so long that it over-proofs and loses structure.
