Formulas Used

Gluten Development Score

gluten_score = round(protein_pct * 5 + mix_minutes * 3 + folds * 5 + (autolyse > 0 ? 10 : 0) + (hydration >= 65 ? (hydration - 65) * 0.3 : 0))

Windowpane Test

windowpane_likely = (protein_pct * 5 + mix_minutes * 3 + folds * 5 + (autolyse > 0 ? 10 : 0)) >= 90 ? 1 : 0

Crumb Openness Factor

crumb_prediction = round((hydration - 55) * 1.5 + folds * 3)

How It Works

How to Estimate Gluten Development

Scoring Formula

Score = (Protein x 5) + (Mix Minutes x 3) + (Folds x 5) + Autolyse Bonus + Hydration Bonus

Interpretation

  • Under 60: Minimal development (biscuits, scones)
  • 60-90: Moderate development (sandwich bread, pizza)
  • 90-120: Strong development (artisan bread, bagels)
  • 120+: Very strong development (high-gluten applications)

    • The windowpane test (stretching dough thin enough to see light through it) typically passes when the score is 90 or above. Autolyse (resting flour and water before adding salt and yeast) contributes significant passive development.

    Worked Example

    12% protein flour, 70% hydration, 10 minutes mixing, no folds, no autolyse.

    protein_pct = 12hydration = 70mix_minutes = 10folds = 0autolyse = 0
    1. 01Protein score = 12 x 5 = 60
    2. 02Mixing score = 10 x 3 = 30
    3. 03Folds = 0 x 5 = 0
    4. 04Autolyse bonus = 0
    5. 05Hydration bonus = (70 - 65) x 0.3 = 1.5
    6. 06Total = round(60 + 30 + 0 + 0 + 1.5) = 92 (strong development)

    Frequently Asked Questions

    What is the windowpane test?

    Pinch off a small piece of dough and gently stretch it between your fingers. If you can stretch it thin enough to be translucent without tearing, the gluten is well developed. If it tears easily, continue kneading or folding.

    Can I develop gluten without kneading?

    Yes. Autolyse (resting flour and water for 20-60 minutes) starts passive gluten development. Stretch-and-fold sets during bulk fermentation continue building structure with minimal effort. Time and hydration also contribute.

    Does salt affect gluten development?

    Salt tightens the gluten network and slows fermentation. Adding salt after the autolyse period (delayed salt method) allows the gluten to hydrate and develop more freely during the initial rest.
