It is too cold
Cool kitchens slow fermentation. If your starter is alive but sluggish, warmth and time may be the missing pieces.

Why Is My Sourdough Starter Not Rising?
If your sourdough starter is flat, weak, or barely bubbling, don’t panic. Most starter problems come down to food, temperature, timing, strength, or dryness — and they can usually be fixed.

Quick Answer
Why your sourdough starter is not rising
Your sourdough starter may not be rising because it is too cold, too hungry, too young, underfed, over-diluted, dried out, or not strong enough yet. A healthy starter needs consistent feeding, a comfortable temperature, fresh flour and water, and enough time to become bubbly and active after feeding.

What is supposed to happen after feeding?
After you feed sourdough starter with fresh flour and water, the culture begins fermenting that food. As it becomes active, it should usually show bubbles, expansion, aroma, and eventually a rise in the jar.
A strong starter usually rises after feeding, reaches a peak, then slowly falls as it uses up its food. That rise-and-fall rhythm is normal. The goal is learning when your starter is active enough to bake with.

Common Causes
Most common reasons starter will not rise
It is hungry
If your starter rose and collapsed, smells boozy, or has liquid on top, it may need fresh flour and water.
It is still weak
Young or neglected starters often need repeated feedings before they can reliably raise dough.
It is drying out
In Albuquerque’s dry air, the surface can dry faster. Keep the jar covered without sealing it airtight.
The feeding is off
Too much old starter or too much fresh food can throw off timing. A consistent routine makes behavior easier to read.
You missed peak
If it rose earlier and looks flat now, it may not be failing. It may simply be past peak and ready for another feed.
Albuquerque Baking Note
Dry air can make starter care feel different
In Albuquerque, dry air can make starter care feel different. The top of the starter can dry out faster, dough can feel tighter, and fermentation timing may not match recipes written for more humid kitchens.
That does not mean your starter is broken. It means you need to watch the jar, not just the clock.
Read the Albuquerque High-Altitude GuideWhen is starter ready to bake with?
Starter readiness is about activity. A starter can have a few bubbles and still not be strong enough to carry bread dough. Look for a starter that is active, airy, expanded, and near peak after feeding.
Bake when it looks like this
- Doubled or close to doubled after feeding
- Bubbly throughout the jar
- Smells pleasantly fermented
- Looks airy, active, and expanded
- Has a rhythm you can begin to predict
Wait when it looks like this
- Flat with very few bubbles
- Sharp, boozy, or very hungry smelling
- Cold and moving slowly
- Brand new and not predictable yet
- Recently collapsed after peak
Build a better routine
Starter problems usually come back to rhythm
If your starter keeps rising unpredictably, collapsing early, or acting hungry, start with a cleaner feeding rhythm. A consistent schedule makes your jar easier to read.

Frequently asked questions
Why is my sourdough starter bubbling but not rising?
If your starter has bubbles but does not rise, it may be too thin, too weak, too cold, or not strong enough yet. Bubbles show activity, but rise shows strength.
How long does it take for starter to rise after feeding?
Timing depends on temperature, feeding ratio, starter strength, and flour. A warm, strong starter may rise quickly, while a cold or weak starter may take much longer.
Can I use starter that has not doubled?
You can use it in discard recipes, but for bread dough you usually want starter that is active, bubbly, expanded, and strong enough to help the dough rise.
Why does my starter rise and then fall?
That is normal. Starter rises as it ferments, then falls after it passes peak and uses up its food. If it has collapsed, feed it again and watch for the next peak.
Should I start over if my starter is not rising?
Not always. If there is no mold or unsafe smell, many weak starters can be rebuilt with consistent feeding, warmth, and time.
