How To Store Sourdough Discard

Natasha Krajnc

This will depend on the maturity of your sourdough starter. If your starter is mature, then it will certainly survive in the fridge for a long time.

However, if your starter is quite young i.e., less than 6 months old, then it won’t last very long in the fridge. The yeast and bacteria will not have been established just yet.

Sourdough discard left on the counter, unfed and unmaintained, will become very sour and acidic. Since it is quite literally a jar of unfed starter, it will eventually be taken over by bad bacteria and mold.

You can certainly freeze your discard especially if you’re planning to use it in future bakes.

For best results, try freezing it one cup at a time. Though the perfect method of preservation is the freezer, sourdough discard is no stranger to freezer burn, which is why it’s best to freeze a little at a time.

As the discard ages, it will become sourer, and emit strong smells similar to nail polish remover. An active sourdough starter will often produce a pool of liquid on its surface called hooch, which is a clear sign that the starter is hungry. Your sourdough starter discard will behave in the same manner.
