Why the timing shifts

Cold kitchen territory — cellars, garages, unheated rooms. Ferment time is 2.5× longer than baseline 76°F. Excellent for flavor development when you have the patience. If your kitchen runs this cold naturally, either move dough to a warmer spot or extend bulk and proof times dramatically. Consider using 20-25% levain instead of 15-20% to compensate for slow activity.

Technique for NY Style Pizza (Sourdough)

Same as Neapolitan but higher hydration and add 2% olive oil + 2% sugar. Bulk 2h, cold retard 24-48h. Stretch to 14-16 inch round. Bake on preheated steel at 550°F for 7-9 min until cheese bubbly and crust golden-brown.

How the math works

Multipliers are piecewise-linear interpolations between reference points measured by Myhrvold et al. in Modernist Bread vol 3. 76°F is the baseline (1.0×); every 10°F drop roughly doubles fermentation time, and every 10°F rise roughly halves it.
