Does Freezing Harm Sourdough Starter?

Can You Freeze Sourdough Starter, or Will That Kill Off All The Yeast?

Freezing your sourdough starter will generally not harm the starter if done correctly. Some yeast in your starter may die off, but there will be more than enough that survive to get your starter active again once it has defrosted.

When Should you NOT Freeze Sourdough Starter?

If your sourdough starter is less than a few months old, then freezing is not recommended. The yeast and bacteria will not have developed enough strength to survive the freezing process.
