Finding a sourdough starter

A sourdough starter, also called levain, is a fermented dough filled with natural yeast. The starter is used to make sourdough bread rise and give it that characteristic sour flavor. If you’ve ended up here, we assume at this point you already have a sourdough starter on hand.

But if you don’t have a sourdough starter, did you know you can make it at home? Here’s our guide on how to make sourdough starter, complete with all our tips. You also can get a sourdough starter from a friend or purchase it online…but what’s the fun in that? Making sourdough starter takes very little hands on time. It takes 5 days of waiting time before the starter is active and ready to go.

Storing sourdough starter

To store your starter, you’ll need a sourdough starter container. Any covered jar will work, but here’s our the sourdough starter container. Just place the starter right into the container, which is now his or her home. (Note: Over time the starter’s home can become gummy: every week or two, take the starter out of the container and wash the container, then replace the starter and follow the normal feeding instructions below.)

You’ll want to store your starter in the refrigerator until you’re ready to make bread. When you make bread, you’ll feed the sourdough starter the night before (see the recipe below), then return the sourdough starter to the refrigerator until you’re ready to bake again.

Feeding sourdough starter

So, you’ve got a sourdough starter and it lives in its container in the refrigerator. What’s the frequency for feeding sourdough starter?

You can leave the starter in the refrigerator for 3 to 4 days at a time between feedings. We recommend feeding sourdough starter at least twice a week for best results.
Remember, if you’re planning to make bread on a given day, you’ll feed sourdough starter the night before you bake. So depending on how often you want to make bread, you may end up feeding your starter more often.
For us, we make a loaf of sourdough bread about 4 times a week, so we feed it 4 times per week (every night before we make bread). If we have a week where we plan to make less bread, we’ll still feed the starter 2 times per week, regardless of whether we’re making bread.
What are the actual steps for how to feed sourdough starter? Go to the recipe below.

If you’re actively using your starter to make our Sourdough Bread recipe, the instructions in the recipe below will allow just enough leftover sourdough starter to have enough starter for the next day’s bread. If you’re not making bread every few days, you’ll need to discard excess starter as part of the feeding process to keep it healthy and happy.

What is a healthy sourdough starter like? A healthy starter smells funky and fruity, in a good way. It’s a floury paste that’s lightly bubbly. If things start to take a turn, see the Troubleshooting section below.

Troubleshooting your sourdough starter

Every once in a while something can go wrong with your starter. If you don’t feed it often enough, the sourdough starter starts to smell like alcohol. You may also find that the starter loses its vibrancy and doesn’t get too bubbly and active after a feeding. Don’t worry, you can always get the starter to recover. Throw away all but about a teaspoon of the starter and nurse it back to life following the instructions for making a sourdough starter. It should take 5 days or less to be healthy again.

What if I go on vacation?

What if you want to go on vacation: what should you do with your sourdough starter? In our experience, we’ve found that if you’re leaving for over a week, it’s best to discard your sourdough starter and start again with the process of making a sourdough starter. Of course if you have a friend or family member who can babysit your sourdough starter, that’s even better! Actually, in Sweden you can hire a babysitter for your sourdough starter. So maybe it’s not so far fetched!

Alright, if you’ve made it this far you’re ready to learn how to feed sourdough starter. See the recipe below!
