Fermentation

Fermentation is the engine of dough development. Yeast makes gas, enzymes keep working, and time changes flavor and structure.

Best ForReading bulk fermentation by dough cues instead of by clock alone.

FocusGas development, timing control, and room-vs-cold workflow.

What Fermentation Is Doing

• Producing CO2 for rise
• Building acidity and aroma
• Improving extensibility over time
• Changing dough strength as gluten relaxes and reorganizes

Basic Workflow

1. Mix dough until evenly hydrated.
2. Ferment in bulk (room or cold, depending on style).
3. Add folds early if dough needs strength.
4. Stop bulk when dough is visibly aerated and alive, not collapsed.

Bulk Fermentation Cues (Use These, Not the Clock Alone)

• Volume: usually 50-100% expansion, style-dependent
• Surface: smoother, slightly domed, small bubbles visible
• Feel: lighter and gassy, not dense and tight
• Edges in container: small gas pockets along the sides

Room vs Cold Fermentation

• Room fermentation moves faster and needs tighter timing.
• Cold fermentation moves slower and gives wider timing tolerance plus deeper flavor.

Cold Fermentation Baseline

• Refrigerate dough 12-48 hours as a practical starting range.
• Keep dough covered to prevent surface drying.
• Expect final proofing to move more slowly after cold storage.

If your dough keeps overshooting, lower yeast or go colder.
If it keeps lagging, increase temperature or give more time.

Common Mistakes

• Waiting for an exact clock time and ignoring dough signals
• Over-warming dough early and losing control later
• Adding too much bench flour instead of using folds/time
• Letting bulk run until dough weakens and collapses

Quick Fixes

• Dough too slow: warmer spot, longer rest, or slightly more yeast next batch
• Dough too fast: cooler spot, shorter bulk, or slightly less yeast next batch
• Dough tight after bulk: longer bench rest before shaping
• Dough weak after bulk: end bulk earlier next time or add one more fold cycle
• Sluggish from fridge: add extra bench time before shaping or baking
• Overproofing during cold storage: reduce yeast slightly next batch
