Why Is My Sourdough Starter Not Rising?

You’ve fed your starter.

You’ve waited.

And…nothing.

Before assuming your sourdough experiment is over, remember that several things can affect how quickly a starter rises.

Your Kitchen May Be Too Cool

Fermentation generally moves faster in warmer conditions and slower in cooler ones.

A chilly kitchen can turn a normally energetic starter into a very sleepy one.

Try finding a comfortably warm location away from excessive heat.

Your Starter May Need More Time

This is particularly important with a newly established or recently reactivated starter.

It may take multiple feeding cycles for activity to become strong and predictable.

Don’t judge it based on a single feeding.

Look Beyond the Height

Is it producing bubbles?

Does it smell fermented?

Did it rise slightly and then fall before you checked it?

Marking the level after each feeding makes these changes much easier to see.

Consider Your Flour

Different flours can produce noticeably different fermentation behavior.

Whole-grain flours contain more of the grain than refined white flour and can sometimes encourage activity in a sluggish starter.

That doesn’t mean you have to permanently change your flour. It’s simply another variable worth understanding.

Check Your Feeding Routine

Feeding too little, too much, or at inconsistent intervals can make it harder to understand your starter’s rhythm.

A kitchen scale makes maintaining consistent ratios much easier.

Be Patient

This might be the least exciting sourdough advice, but it’s some of the most useful.

Don’t change five variables every few hours.

Feed it.

Mark the jar.

Keep it comfortably warm.

Watch.

Learn.

Sourdough works on fermentation’s schedule—not ours.

Starting From Scratch?

If you’d rather begin with an established culture, you can find dehydrated sourdough starter from Lettuce Live Living and reactivate it in your own kitchen.

All you need from there is flour, water, and a little patience.
