Stir and Feed
EasyReincorporate and nourish the starter.
- Stir the hooch back in or pour it off
- Discard all but 50g of starter
- Feed with 50g flour and 50g water
- Feed again in 12 hours
Starter Separating
StarterA starter that separates into layers with liquid (hooch) on top has been hungry too long. This is normal and easily fixed with consistent feeding.
Starter Separating in sourdough most often traces back to Separation occurs when starter runs out of food and the alcohol produced by fermentation rises to the top, a starter feeding-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 starter separating 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.
- 1Pour off or stir in the liquid (hooch)
- 2Discard most of the starter and feed with fresh flour and water
- 3Feed again in 12 hours if still sluggish
What are the detailed fixes for starter separating?
If the quick steps above did not resolve things, these deeper adjustments rework the mix, fermentation, or handling stage where starter separating usually originates. Each card explains what to change, the reason it works, and the baking stage it belongs to.
Aggressive Feeding
EasyRebuild starter strength quickly.
- Keep only 25g starter
- Feed with 100g flour and 100g water
- The larger ratio dilutes accumulated acids
- Should be active within 24-48 hours
What causes starter separating in sourdough?
Separation occurs when starter runs out of food and the alcohol produced by fermentation rises to the top. Contributing factors include: Starter not fed frequently enough, Too much time between feedings, Warm environment accelerating consumption, Too much starter kept relative to feed, Neglected in refrigerator too long.
How do I prevent starter separating 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 starter separating, so you build the fix into your process instead of reacting to a dough that has already drifted.
- Feed starter before it fully collapses and separates
- Refrigerate if not baking frequently—feed once weekly
- In warm weather, feed twice daily or refrigerate
- Use a larger ratio of flour to starter for less frequent feeding
