Is my sourdough starter dead? (Probably not - Let's Check!)
Starters can look a little tired, sluggish, or even downright sad sometimes, but most of the time, they just need a little love (and a good meal).
The good news? Sourdough is tough. Like, really tough.
Before you even think about tossing yours out, let’s walk through a few easy signs to tell whether it’s truly gone — or just needs a little encouragement to spring back to life. You might be just one feeding away from a happy, bubbly starter again!
Signs that your sourdough starter is STILL alive
- It still smells pleasant (like yeast, beer, or a little tangy).
- You see some bubbles, even if they are small or slow.
- After a fresh feeding (flour + water), it rises at least a little within 4–8 hours.
- It’s not completely separated into clear water with a foul smell (some “hooch” on top is normal, though — just stir it in or pour it off).
My sourdough starter has a dark liquid on top, is it dead?
No panic — the dark liquid on your sourdough starter is called hooch! 🥃It does not mean you have killed your sourdough starter.
Here’s the quick breakdown:
-
- What it is: Hooch is a natural alcohol that your starter produces when it’s hungry or hasn’t been fed in a while.
- What it means: Your starter isn’t dead — it’s just asking politely (or dramatically) for food.
- What to do: You can either stir it back in or pour it off before feeding your starter. Both ways are totally fine! Stirring it in makes your starter a little more sour over time; pouring it off keeps the flavor milder.
Signs that your sourdough starter is dead and you need to toss it.
What can you do to bring back your sourdough starter back to life?
Please don’t give up on your starter too fast! Your starter is probably not dead and you will most likely be able to bring it back to life by following the instructions provided below.
Feeding the sourdough starter is the best way...
- Feeding it once a day using a 1:1:1 feeding ratio (1 part starter, 1 part water, 1 part flour). This ratio will speed things up.
- Giving it warmer conditions (around 85°F is ideal). Use a dough proofer! My favorite ones are the Brod and Taylor and the Raisenne.
Provide a high quality flour
Never forget the sourdough starter is a living creatured and a mix of natural yeast and bacteria. Therefore the use of high quality flour when it is not behaving as it should is a really good trick!
What flour should you use to feed the starter?
Fresh milled flours are the way to go! This is not something you can get at your typical grocery store. You might have a local mill where you live, if not make sure to check out Castle Valley Mill.
It is very close to the Studio and they ship nationwide or if you are local you can stop by and shop at their store!
Warm conditions
The starter thrives at 85F, so it is very important to be able to provide a cozy environment for the starter after a feed. I cannot emphasize enough the use of the proofers I mentioned above. They make your
