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 Focaccia Genovese

Mix dough with olive oil incorporated. 3h bulk. Heavily oil sheet pan. Transfer, stretch to fill. Proof 90 min. Before baking: mix 2 tbsp olive oil + 2 tbsp water + 1 tsp salt, brush over surface, dimple aggressively. Bake 475°F 18-22 min until deep golden edges.

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.
