What is Sourdough Discard?

In general terms, a sourdough starter is a mixture of flour and water that has been allowed to ferment. The process of fermentation allows the growth of beneficial bacteria and wild yeasts, which in turn gives sourdough bread its unique flavor, texture, and leavening power.

If you maintain a sourdough starter, you'll need to "feed" it on a regular basis to keep the wild yeasts and bacteria alive and active. The general rule of thumb is to feed your starter once a day when stored at room temperature, or once a week when stored in the fridge, although this may vary depending on how often you use it.

As part of the feeding process, you'll need to remove some of the existing starter before adding fresh flour and water. The amount you remove will depend on the size of your sourdough starter - for example, if you have a small starter, you might only need to remove a few tablespoons.

The unfed starter that is leftover after you've taken some starter to feed is often referred to as sourdough discard. You can think of it as the "waste" product from keeping a healthy sourdough starter; however, it's really anything but.

Is Sourdough Discard Useful?


You shouldn't actually be discarding your extra sourdough starter! Discard is basically flour and water and flavor because it's full of wild yeast and bacteria just like your starter, which means it can be used to make all sorts of recipes - sweet or savory - to add a sourdough flavor and improve the texture.

Leftover sourdough discard is a fantastic ingredient to have on hand, and once you get into the habit of saving it, you'll be surprised at just how many ways you can put it to use.

While discard does not have the power to leaven bread it doesn't mean it's not useful to us, or that it can't be used in baking recipes. Discard can be used in bread recipes that call for yeast, it can be used in baked goods that rely on baking powder or baking soda for leavening, or it can be used in things that don't require rising like cookies and crackers.

How to Store Sourdough Discard

If you're not ready to use your discarded sourdough starter right away, don't worry, there are a few ways that you can store sourdough discard for future use.

Room Temperature:

The easiest way to store sourdough discard is at room temperature in a covered jar or container. If you're planning on using your discard within the next few days, this is the method for you. Just make sure that your container is covered so that your discard doesn't dry out.

Be aware though that as the yeast and bacteria consume the available food, they'll start to die off as the food supply dwindles causing the build-up of alcohols (HOOCH) and the flavor will quickly become overpowering. If your discard creates hooch, simply stir it in if you like the sour flavor or pour it off before using.

There are no preparations required for room temperature sourdough discard - it is ready to use when you are.

In my (un)professional opinion, storing excess starter in the fridge is the BEST way of keeping it.

I keep a labeled and dated container in the fridge and add discard to it each time I feed my sourdough starter. The bonus to storing it in the fridge is that it can be kept in there almost indefinitely. I mean, if something catastrophic happens, you could even use discard toREVIVE YOUR SOURDOUGH STARTER!

Yes, your fridge is cold and dark and it slows down yeast activity, but we know fromPROOFING SOURDOUGH IN THE FRIDGEthat it doesn't completely stop fermentation or flavor development.

Discard kept in the fridge will have a slightly different flavor than a warmer discard. This is because the bacteria continue to break down available starches into lactic and acetic acid increasing the sour flavor, while yeasts dominate the flavor profile at room temperature.

I prefer to use my discard within 7 days of the first addition to my discard container, otherwise, you risk too much sour flavor!

To use sourdough discard that's been stored in the fridge and place it on the counter to warm up for 2-3 hours before using it in your favorite sourdough discard recipes.

If you're baking a lot, or you get overtaken by sourdough starter cause you're not discarding as much as you should, you can definitely toss some of that leftover starter in the freezer.

Freezing is a great way to store a lot of discard for long periods of time (months!) without affecting the quality or flavor too much.

To freeze, transfer the discard to a labeled and dated freezer-friendly bag, squeeze the air out, and freeze the bag flat for later use. It is important to label, especially if you're like me and you have multiple different cultures in the freezer at all times, like rye sourdough starter and Amish Friendship Bread starter.

To use frozen discard, just pull it out of the freezer and let it thaw on the counter until completely warmed to room temperature before using.
