Starter storage depends on how often you bake
There is no single perfect way to store sourdough starter. The best method depends on how often you bake, how much maintenance you want, and whether you need your starter active every day or only once in a while.
The simplest rule is this: the more often you bake, the more active your starter should stay. The less often you bake, the more helpful cold storage or dried backup becomes.
Frequently asked questions
Can I store sourdough starter in the fridge?
Yes. Fridge storage is a good option if you bake occasionally. Feed the starter before storing it, then wake it up before baking.
How long can sourdough starter stay in the fridge?
Fridge starter can usually go longer between feedings than counter starter, but it still needs care. Feed it regularly and always check smell, appearance, and activity before baking.
Can I dry sourdough starter?
Yes. Starter can be dehydrated for longer storage, travel, backup, or gifting. It must be reactivated with flour and water before baking.
How do I wake up starter from the fridge?
Feed it fresh flour and water, keep it in a comfortable spot, and wait for bubbles, rise, and peak activity. Sluggish starter may need more than one feeding.
Should I store starter sealed airtight?
Do not seal active starter airtight at room temperature. It gives off gas as it ferments. Use a loose lid or breathable cover depending on your routine.
