Sourdough Lamination: When and How to Use It

Short answer: lamination involves stretching dough into a thin sheet on a wet counter, then folding it back. It's done once during bulk for high-hydration dough (78%+) to redistribute gas and develop even crumb structure.

What lamination is

Lamination:

• Stretching dough into a thin sheet
• Folding it back like a letter
• Returning to the bulk container

It's an alternative to one stretch-and-fold during bulk.

Why it matters

For high-hydration dough:

• Gas pockets can collect unevenly
• Gluten development is slower
• Standard folds may not be enough

Lamination redistributes gas evenly and aligns gluten in a single sheet, then bunches it back together. The result is a more uniform structure.

When to use lamination

Use lamination for:

• 75%+ hydration dough
• High-percentage whole wheat
• Adding inclusions evenly (cheese, nuts, fruit)
• When you want big, evenly-distributed crumb holes

Skip lamination for:

• Low hydration (65–70%) — not needed
• Pan loaves — overkill
• Quick-bake recipes — not enough time

The technique

After 60 minutes of bulk (typically Set 2 of folds):

1. Wet your counter with water (no flour!)
2. Tip dough out (gently)
3. Wet your hands
4. Spread dough into a thin rectangle (12x16 inches)
5. Use both hands to stretch evenly
6. Stop when you see translucency (don't tear)
7. Fold like a letter (left third over center, right third over)
8. Then fold from top to bottom (like a bedsheet)
9. Return to bulk container, seam-down
10. Continue bulk

The whole process takes 2 minutes.

Why a wet counter

A wet counter:

• Prevents sticking
• Doesn't add flour to the recipe
• Allows gentle stretching

A floured counter:

• Sticks less but adds flour
• Can dry out the dough surface

Wet is better for lamination.

Adding inclusions

Lamination is the perfect time to add inclusions:

For cheese sourdough (200g cubed cheese):

1. Stretch dough flat
2. Sprinkle cheese evenly across
3. Fold dough back
4. Cheese is now distributed throughout

For nut/dried fruit sourdough (80g each):

1. Stretch flat
2. Sprinkle nuts and fruit evenly
3. Fold back

This produces even distribution that random folding can't achieve.

Common mistakes

Stretching too thin:

• Tears the gluten
• Creates weak spots
• Dough collapses

Stretching too thick:

• Doesn't accomplish redistribution
• No benefit over normal folds

Over-laminating (multiple times in one bulk):

• Over-develops gluten
• Tearing during shaping
• Once is enough

When dough resists

If the dough resists stretching:

• Wait 30 minutes
• Try again (gluten may be too tight)
• Or skip lamination this bake

Not all dough wants lamination. Listen to it.

A high-hydration test

For 80% hydration dough, compare two bakes:

• Bake 1: 4 standard folds
• Bake 2: 3 standard folds + 1 lamination

The Bake 2 crumb will have:

• More even hole distribution
• Bigger, rounder holes
• More dramatic open crumb

For high-hydration sourdough, lamination is the secret weapon.

A pan-loaf consideration

For sandwich loaves, skip lamination:

• The loaf is meant to be tight-crumbed
• Even lamination doesn't help
• Standard folds are sufficient

A whole-grain note

For 30%+ whole wheat dough:

• Lamination helps redistribute bran
• More uniform crumb
• Worth the extra step

For 50%+ whole wheat: lamination is essential.

Lamination vs. coil folds

Coil folds:

• Lift dough from the middle
• Let ends fall together
• More gentle than stretch and fold
• Good for very high hydration

Lamination:

• Stretches dough flat
• Distributes evenly
• One-time during bulk
• Best for inclusions

You can use both methods on the same dough. Lamination once + 3 coil folds is a great approach for 80% hydration.

A timing note

Lamination is best done:

• After 60 minutes of bulk
• When gluten is partially developed
• Before significant rise

Don't lamine in the first 30 min (too undeveloped) or after 2 hours (too risen).

A quick demonstration

For your first lamination:

• Make a small dough (250g flour)
• Practice the stretch
• Get comfortable with the size and feel
• Then apply to a real bake

Skill comes from practice.

A final note

Lamination is one of those techniques that separates intermediate from advanced sourdough bakers.

It's not necessary for every bake. But for high-hydration loaves with open crumb, it's a meaningful upgrade.

Try it once on your next 78%+ hydration bake. The crumb difference will be obvious.
