Coil-Fold โ€“ Gentle Gluten Development for Wet Sourdough

How to perform the coil-fold: a gentle technique for strengthening very wet sourdoughs. Step-by-step guidance, timing, common mistakes and scientific rationale.

Why This Technique?

A very gentle folding method that strengthens gluten in high-hydration doughs without tearing or overworking the crumb.

The coil-fold lifts the dough vertically and lets gravity and the dough's own weight create a controlled stretch. This aligns gluten strands and consolidates gas pockets with less mechanical stress than classic stretch-and-folds, making it ideal for very wet doughs (75%+ hydration) and fragile flours. The technique also redistributes enzymes and yeast evenly through the mass, supporting consistent fermentation [1][2].

โœ“ Minimizes tearing in very wet doughs โœ“ Builds strength while preserving open crumb potential โœ“ Requires less surface friction than other folds โœ“ Works well in a rounded [large mixing bowl](https://amzn.to/45rc1Gk)

When to Use

โœ“ Suitable for:

  • โ€ข Wheat-based doughs above ~75% hydration
  • โ€ข Breads where an open, irregular crumb is desired
  • โ€ข Doughs made with weak or partly oxidized flours

โœ— Not suitable for:

  • โ€ข Very stiff doughs (<65% hydration) โ†’ Coil-fold offers little benefit; standard kneading or stretch-and-folds are more effective
  • โ€ข Pure rye doughs โ†’ Rye lacks gluten network; prefer different handling methods

Step by Step

Preparation:

Have clean, slightly wet hands (tap water) to prevent sticking. Use a [dough scraper](https://amzn.to/3LR1f5E) if needed to lift edges. Work in a rounded [large mixing bowl](https://amzn.to/45rc1Gk) or on a lightly oiled surface.

1

Slide the dough scraper or your wet hand under the dough near the center to lift it vertically from the bottom.

๐Ÿ‘€ Dough lifts in a soft column from the bowl surface
2

Lift the dough in a gentle column (a 'coil') about 6โ€“10 inches high โ€” stop well before the point of tearing.

๐Ÿ‘€ Column of dough hangs without breaking
3

Allow the raised column to fold back onto itself; guide it to rest on the opposite side of the dough mass. You are effectively coiling the dough into itself.

๐Ÿ‘€ Dough layers fold into a tighter, taller mass
4

Rotate the bowl 90ยฐ and repeat the lift-and-coil on a new quadrant, so strength builds from multiple directions.

๐Ÿ‘€ All four sides show slight rounding and tension
5

After one full circuit (4 coils), cover and rest. The dough should feel more cohesive and show a smoother surface.

๐Ÿ‘€ Surface is smoother and dough holds shape better

How Often?

Use 3โ€“4 coil-fold sets during the first half of bulk fermentation; fewer sets for very weak flours.

After 20โ€“30 min
Set 1
After 40โ€“60 min
Set 2
After 80โ€“100 min (optional)
Set 3
After 120 min (only for very slack doughs)
Set 4

How do I know it's enough?

The dough forms a cohesive dome, shows surface tension, and resists excessive spreading when gently nudged; if it tears easily, continue with gentler coils rather than more frequent folding [1][2].

Common Mistakes

โŒ Lifting too high or too fast

Problem: Causes tearing and destroys the forming gluten network

Solution: Lift slowly and stop as soon as the dough thins visibly

โŒ Using dry hands

Problem: Dough sticks and rips

Solution: Keep hands lightly wet and use a [dough scraper](https://amzn.to/3LR1f5E) to assist

โŒ Treating coil-fold like a stretch-and-fold

Problem: Applying lateral shear defeats the gentleness of the method

Solution: Focus on vertical lifts and gentle placement; avoid aggressive stretching along the bowl surface
