No, Your Sourdough Starter Isn’t Dead (Probably)
A real-talk troubleshooting guide for beginner panic moments
We need to talk about that jar of flour and water on your counter.
You know the one.
The one you’ve been nervously peeking at every few hours.
The one that smells… funky? Or maybe not funky enough?
OR
The one you were pretty sure was “alive” yesterday, but now looks suspiciously flat, quiet, and kinda sad.
Good news:
Your sourdough starter probably isn’t dead.
More good news:
Even if it’s struggling, there’s a very good chance you can bring it back.
Because here’s the truth: sourdough starters are a lot more resilient than we give them credit for. They’re not delicate little pets—they’re wild microbial ecosystems. And just like people, they have off days. So before you throw it in the trash and swear off homemade bread forever, let’s troubleshoot.
Symptom #1: “It’s Not Bubbling”
Translation: You’re looking for signs of life, but not seeing the drama you expected.
Possible causes:
• It’s still early. Starters can take 5–7 days (or more) to get active.
• The room is too cold. Microbes like it cozy—think 70–75°F (21–24°C).
• You used chlorinated tap water. Chlorine can mess with microbial growth.
• You’re not feeding it enough (or often enough).
Fix it:
Give it time. Make sure you’re feeding it at the very least 1:1:1 (starter:flour:water by weight) daily. Use filtered or dechlorinated water if you can. And move it somewhere warmer—top of the fridge, inside the oven with the light on, or a cozy corner.
Symptom #2: “It Smells Bad”
Translation: You opened the jar and immediately recoiled. Fair.
Good smells: tangy, fruity, vinegary, beery, yeasty
Weird but still okay smells: nail polish remover (acetone), sour apple
Bad signs: mold (fuzzy, colored patches), pink/orange tinge
Fix it:
If it smells like acetone or alcohol, it’s hungry. Feed it! Twice a day if needed.
If you see mold or streaky discoloration on the actual starter, toss it and start fresh. Surface hooch (a gray liquid) is fine—just pour it off or stir it in.
Symptom #3: “It Rose Yesterday, But Now It’s Flat Again”
Translation: Your starter peaked… and now it looks like a deflated balloon.
What’s happening: That’s totally normal! A healthy starter rises and falls—it means the yeast ate the sugars in the flour, produced gas, and then ran out of food.
Fix it:
Use a rubber band or mark the jar to track how much it rises after a feeding. If it’s consistently rising and falling within 4–8 hours, it’s ready to bake with—or at least close.
Symptom #4: “There’s Liquid on Top”
Translation: It looks like your starter is sweating or crying.
That liquid is called hooch. It’s just alcohol from hungry yeast.
Fix it:
• If it’s clear or gray, no problem. Stir it back in or pour it off before feeding.
• If it’s pink or orange, that’s a no from me. Toss it.
Either way: your starter is telling you it’s time for a meal.
Symptom #5: “I Forgot to Feed It for Days”
Translation: Life happened. Same.
If it’s been:
• 1–2 days: No biggie. Resume feeding as normal.
• 3–7 days: Pour off the hooch, give it a big feed, and it’ll probably bounce back.
• More than a week: You might need a few back-to-back feedings to revive it.
• Over a month in the fridge: Smell it. No mold? Try reviving it with a few days of regular feeds.
Sourdough starters are the ultimate comeback queens. You’re probably fine.
When to Actually Start Over
• Visible mold
• Pink or orange streaks
• You just don’t feel good about it and would rather have peace of mind
Starting fresh is not failure. It’s experience. And your new starter will be better for it.
Final Thoughts: Breathe. It’s Going to Be Okay. Sourdough starter drama is basically a rite of passage. Everyone who’s ever baked bread has asked, “Did I kill it?” at some point. And most of us have Googled something like “is my sourdough dead?” in a panic. You’re not alone.
Keep feeding. Keep observing. Keep going.
Stay tuned—and stay cultured.
