Pain de Campagne (Variant with Rye) — Timing by Kitchen Temperature
Baseline: 4h bulk + 12h proof at 76°F. Adjust for your kitchen below.
The full Pain de Campagne (Variant with Rye) schedule (76°F baseline)
Pain de Campagne (Variant with Rye) is a hearth-style sourdough from France. From a ripe levain to a cooled loaf it runs about 18.1 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.
| Stage | Duration | Elapsed from mix |
|---|---|---|
| Levain build to peak (before mixing) | ~5 h | −5 h |
| Autolyse (flour + water rest)builds extensibility before the levain goes in | 30 min | 30 min |
| Mix — add levain & salt | 18 min | 48 min |
| Bulk fermentation with stretch-and-folds3–4 sets of folds in the first ~2 hours, then leave it to rise | 4 h | 4.8 h |
| Pre-shape & bench rest | 24 min | 5.2 h |
| Final shape | 12 min | 5.3 h |
| Cold retard (refrigerator)develops flavour + firms the dough for scoring | 12 h | 17.3 h |
| Bake — 500°F in a dutch ovenabout 45 minutes | 48 min | 18.1 h |
A sample overnight clock plan
One realistic way to fit Pain de Campagne (Variant with Rye) 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 PM — Autolyse.
- 5:30 PM — Mix.
- 5:45 PM — Bulk fermentation with stretch-and-folds.
- 9:45 PM — Pre-shape & bench rest.
- 10:09 PM — Final shape.
- 10:18 PM — Cold retard.
- 10:18 AM — Bake.
- 11:03 AM — 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 Pain de Campagne (Variant with Rye) 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.
Pain de Campagne (Variant with Rye) timing — FAQ
How long does Pain de Campagne (Variant with Rye) take start to finish?
Plan on a ~5-hour levain build first, then about 18.1 h of dough-day work at a 76°F baseline — most of which is a hands-off 12 h cold retard in the refrigerator, so active time is only ~6.1 h. Warmer kitchens run faster and cooler ones slower; use the temperature table below to re-time every stage.
How long is the Pain de Campagne (Variant with Rye) bulk ferment?
4 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 4 h mark. Multiply by your kitchen's temperature factor (table below) to re-time it.
Can I bake Pain de Campagne (Variant with Rye) the same day instead of cold-retarding?
Yes — replace the 12 h refrigerator retard with a 1.5 h–2.5 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 Pain de Campagne (Variant with Rye) 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).
