Consistent Feeding Schedule
EasyRegular feeding encourages activity.
- Feed every 12 hours at same time
- Use 1:1:1 ratio (starter:flour:water)
- Keep at 75-80°F
- Look for bubbles and rise within a week
Starter Not Rising
StarterA starter that will not rise lacks the yeast and bacterial activity needed for bread baking. This can happen with new starters or neglected mature ones. With proper care, most starters can be revived.
Starter Not Rising in sourdough most often traces back to Inactive starter results from insufficient yeast population, wrong temperature, irregular feeding, or contamination, 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 not rising 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.
- 1Feed with equal parts flour and water by weight and place in a warm spot
- 2Ensure temperature is 75-80°F for optimal activity
- 3Wait 12-24 hours before checking for activity
What are the detailed fixes for starter not rising?
If the quick steps above did not resolve things, these deeper adjustments rework the mix, fermentation, or handling stage where starter not rising usually originates. Each card explains what to change, the reason it works, and the baking stage it belongs to.
Whole Grain Boost
EasyWhole grains provide more nutrients.
- Replace half the flour with whole wheat or rye
- These flours have more wild yeast
- Feed twice daily
- Return to regular flour once active
What causes starter not rising in sourdough?
Inactive starter results from insufficient yeast population, wrong temperature, irregular feeding, or contamination. Contributing factors include: New starter not yet established, Temperature too cold, Irregular feeding schedule, Chlorinated water affecting microbes, Starter contaminated with mold.
How do I prevent starter not rising 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 not rising, so you build the fix into your process instead of reacting to a dough that has already drifted.
- Feed starter at consistent times—yeast thrives on routine
- Keep starter at 75-80°F for optimal activity
- Use filtered or bottled water if tap water is heavily chlorinated
- Feed with unbleached flour for more nutrients
