Stretch and Fold – Technique for Better Sourdough

How to use the stretch-and-fold technique to get more volume and better structure in your sourdough. Step-by-step guide.

Why This Technique?

Develops gluten structure WITHOUT intensive kneading. Especially gentle for high hydration doughs.

When stretching and folding, you align the gluten strands and strengthen the network that later holds the gas bubbles. At the same time, you redistribute fermentation activity throughout the dough, improving uniformity and flavor development [1][4]. The technique aerates the dough gently so you preserve larger gas cells that support oven spring [7].

✓ Less work than kneading ✓ Better structure for wet doughs ✓ Gentler on flour flavors ✓ Easier to learn

When to Use

✓ Suitable for:

  • • Wheat doughs with high hydration (>70%)
  • • Wheat doughs in general
  • • Spelt doughs (gentle on fragile gluten)

✗ Not suitable for:

  • • Pure rye doughs → No gluten to develop
  • • Very stiff doughs (<60% hydration) → (Use traditional kneading)

Step by Step

Preparation:

Wet hands (water, not oil) and have a [large mixing bowl](https://amzn.to/45rc1Gk) ready. Weigh ingredients on a [kitchen scale](https://amzn.to/4pUMVHi) for consistent hydration.

1

Grab one side of the dough in the bowl with wet hands or use a dough scraper to lift if very sticky.

👀 Dough is soft and stretchy
2

Pull the dough up until just before it tears — you want thin, not broken. For many home bakers this is 12–20 inches of stretch depending on hydration [2][4].

👀 Dough becomes thin but doesn't tear
3

Fold the stretched piece over the remaining dough so it lies on top; this folds gas pockets inward and builds layers.

👀 Dough layer lies on top of the dough
4

Rotate the bowl ~90° and repeat on each side (or perform coil folds for very slack doughs). Use a dough scraper to help lift if needed [3][6].

👀 Now all 4 sides
5

After a set of folds cover the bowl and rest 30–45 minutes; you'll notice the dough tighten and gain strength between sets [1][5].

👀 Dough is visibly tighter/tauter

How Often?

3-4 sets during the first 2 hours of bulk fermentation.

After 30 min
Set 1
After 60 min
Set 2
After 90 min
Set 3
After 120 min (optional)
Set 4

How do I know it's enough?

Dough feels taut, holds its shape better, surface is smooth instead of rough and a gentle poke leaves a slow spring back — signs the gluten network is established [1][3].

Common Mistakes

❌ Letting the dough tear

Problem: Destroys built-up structure

Solution: Stretch slower, stop before tears; use coil folds or more gentle bowl folds for slack dough [4][6].

❌ Folding too often

Problem: Dough becomes tough, fermentation can be disrupted

Solution: Follow a 2-hour window for most recipes; allow uninterrupted bulk after the last set so yeast can expand the created network [5].

❌ Dry hands

Problem: Dough sticks, tears

Solution: Wet your hands with water before each fold to reduce sticking and avoid adding flour that alters hydration [2][11].

Alternative Techniques

Coil Fold

Even gentler, for very wet doughs

Slap and Fold

Faster gluten development for experienced bakers

Machine Kneading

Large quantities, stiff dough
