Uneven Rise

Bulk Fermentation

Dough that rises unevenly during bulk fermentation often indicates uneven temperature, incomplete mixing, or inconsistent starter distribution.

Uneven Rise in sourdough most often traces back to Uneven rise occurs when one side of the dough ferments faster, usually due to temperature variations or incomplete mixing, a bulk fermentation-stage problem you can usually correct mid-bake. This page lists 3 immediate interventions to try on the current batch plus 4 adjustments to stop it recurring. Fixes assume a 68-72°F kitchen and an active, ripe starter.

How do I fix uneven rise right now?

Work through these reversible steps on the batch in front of you, in order. Each one targets a different failure mode, so the first match is usually the fix — stop as soon as the dough responds and resume your normal process from there.

  • 1Perform a set of stretch and folds to redistribute
  • 2Move container to ensure even temperature exposure
  • 3Turn the container 180 degrees periodically

What are the detailed fixes for uneven rise?

If the quick steps above did not resolve things, these deeper adjustments rework the mix, fermentation, or handling stage where uneven rise usually originates. Each card explains what to change, the reason it works, and the baking stage it belongs to.

Redistribute with Folds

Easy

Folding evens out fermentation.

  1. Perform stretch and folds on all four sides
  2. This redistributes starter and temperature
  3. Rotate container to new position
  4. Continue bulk fermentation

Check Heat Sources

Easy

Identify and address uneven heating.

  1. Check for nearby heat sources (oven, window)
  2. Move to more neutral location
  3. Or rotate container regularly
  4. Aim for consistent temperature around dough

What causes uneven rise in sourdough?

Uneven rise occurs when one side of the dough ferments faster, usually due to temperature variations or incomplete mixing. Contributing factors include: Dough near heat source on one side, Starter not mixed in evenly, Temperature gradient in proofing spot, Direct sunlight on one side, Draft affecting one side.

How do I prevent uneven rise next time?

Prevention is easier than a mid-bake rescue. The tips below target the variables — starter timing, hydration, temperature, and handling — that most often set up uneven rise, so you build the fix into your process instead of reacting to a dough that has already drifted.

  • Place dough in location with consistent temperature
  • Mix starter thoroughly into dough
  • Rotate container if near heat source
  • Use stretch and folds to even out fermentation
