Sourdough Starter Troubleshooting: 7 Common Problems and How to Fix Them
If your sourdough starter isn't behaving the way you expected, don't worry—every baker has been there.
A sluggish starter, strange smells, watery texture, or poor rise are all common problems. The good news is that most of them are easy to fix once you understand what's happening.
Here are seven of the most common sourdough starter issues and their solutions.
1. My Starter Won't Rise
The most common cause is temperature.
Sourdough microorganisms become much less active in a cool kitchen. If your room temperature is below 72°F (22°C), fermentation slows significantly.
Try moving the starter to a warmer spot (75–80°F / 24–27°C) and continue feeding it on a regular schedule.
Sometimes patience is the only ingredient missing.
2. My Starter Smells Like Acetone
A sharp acetone or nail polish smell usually means your starter is hungry.
Discard most of the starter and feed it with fresh flour and water. If necessary, feed it twice a day until the pleasant sour aroma returns.
3. There's Liquid on Top
The liquid, often called hooch, is simply a sign that your starter has run out of food.
You can pour it off or stir it back in before feeding. Either way, it's time for a fresh meal.
4. My Starter Has Mold
If you see pink, orange, green, blue, or black fuzzy spots, it's safest to throw the starter away.
Mold cannot be removed safely from sourdough starter.
Always start again with a clean jar and fresh ingredients.
5. My Starter Rises and Then Falls
This is completely normal.
A healthy starter rises, reaches its peak, and then slowly collapses as the yeast and bacteria consume the available food.
Learning to recognize the peak is one of the most valuable sourdough skills.
6. My Starter Is Too Sour
An overly sour starter is usually the result of infrequent feedings or consistently warm temperatures.
Regular feedings with fresh flour and water help restore balance.
7. How Do I Know When My Starter Is Ready?
Don't rely only on the clock.
A mature starter should:
- Double in volume
- Be full of bubbles
- Smell pleasantly tangy
- Have a light, airy texture
- Reach its highest point before beginning to fall
These signs are much more reliable than simply counting hours.
