Neapolitan Pizza (Sourdough) — Timing by Kitchen Temperature

Baseline: 2h bulk + 24h proof at 76°F. Adjust for your kitchen below.

The full Neapolitan Pizza (Sourdough) schedule (76°F baseline)

Neapolitan Pizza (Sourdough) is a lean sourdough from Italy (Naples). From a ripe levain to a cooled loaf it runs about 27.3 h of dough-day time on top of a ~5-hour levain build. Every duration below is the 76°F baseline — scale it with the temperature table lower down for your own kitchen.

A sample overnight clock plan

One realistic way to fit Neapolitan Pizza (Sourdough) around a normal day, at ~76°F. Shift the whole thing earlier or later to suit — only the gaps between stages matter.

  • 12:00 PM — feed the levain (peaks in ~5 h).
  • 5:00 PMAutolyse.
  • 5:30 PMMix.
  • 5:45 PMBulk fermentation with stretch-and-folds.
  • 7:45 PMPre-shape & bench rest.
  • 8:09 PMFinal shape.
  • 8:18 PMCold retard.
  • 8:18 PMBake.
  • 8:20 PM — loaf out of the oven; cool at least 1 hour before slicing.

Reading each stage by feel

The clock is a guide; the dough is the real timer. Levain is ready at its peak — domed and just starting to recede, floating in water. Bulk is done at a 50–75% rise with a bubbly, jiggly, domed mass — under-shooting gives a tight crumb, over-shooting a slack, gummy one. Proof is judged by the poke test: a slow, partial spring-back. Because Neapolitan Pizza (Sourdough) cold-retards, you can bake straight from the fridge — cold dough scores more cleanly.

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.

Neapolitan Pizza (Sourdough) timing — FAQ

How long does Neapolitan Pizza (Sourdough) take start to finish?

Plan on a ~5-hour levain build first, then about 27.3 h of dough-day work at a 76°F baseline — most of which is a hands-off 24 h cold retard in the refrigerator, so active time is only ~3.3 h. Warmer kitchens run faster and cooler ones slower; use the temperature table below to re-time every stage.

How long is the Neapolitan Pizza (Sourdough) bulk ferment?

2 h at 76°F. It's done when the dough has risen 50–75%, domed, and jiggles when you shake the container — not strictly at the 2 h mark. Multiply by your kitchen's temperature factor (table below) to re-time it.

Can I bake Neapolitan Pizza (Sourdough) the same day instead of cold-retarding?

Yes — replace the 24 h refrigerator retard with a 3 h–4.8 h room-temperature proof and bake once a floured poke springs back slowly and only partway. You trade some flavour depth and scoring ease for speed.

When is Neapolitan Pizza (Sourdough) fully proofed and ready to bake?

Use the poke test: flour a finger, press ~1 cm into the shaped loaf. Ready dough springs back slowly and only partway, leaving a slight dent. Instant spring-back = under-proofed (give it more time); no spring-back and a dense feel = over-proofed (bake immediately, next time shorten the proof).
