Sourdough Discard 101 (2024)


How do I know if my sourdough discard is good? ›

You can store mature sourdough discard in the refrigerator indefinitely. As long as there is no mold, it is good to use. It may develop a grayish liquid on top called “hooch” which can be poured off before use or stirred in. If you stir it in, the flavor will become more sour.

What is 100 hydration sourdough starter discard? ›

At 100% hydration, sourdough discard is 50/50 water and flour. Subtract the percentage of hydration and flour from a recipe if modifying a recipe to add discard.

How quickly do I need to use sourdough discard? ›

When you are ready to bake, remove the discard from the fridge and let it come to room temperature. I recommend keeping sourdough discard for up to one week. If needed, mark the date on the container in your refrigerator. After one week, there is a higher chance of the discard growing bad bacteria or mold.

Can you use 2 day old sourdough discard? ›

You can use old sourdough discard if it's been stored in the fridge, however, you really want to use it up within a week - 2 weeks max.

Can you use day 1 sourdough discard? ›

Remember, you can't use the discard from your homemade sourdough starter for the first 7 days. You can use sourdough discard in all kinds of sourdough discard recipes, including these no wait sourdough recipes, overnight sourdough discard recipes and sourdough discard recipes that use up a lot of discard.

Can I use a month old sourdough discard? ›

Stored in the freezer, sourdough discard will theoretically keep indefinitely. I've left it in the freezer for as long as six months, untouched (i.e., I don't add or remove discard). Before using it, let it thaw in the refrigerator or at room temperature, never in the microwave. The microwave will cook/kill it.

Do you have to discard sourdough starter every time you feed it? ›

With each sourdough starter feeding, you'll be discarding some to avoid it from becoming overly acidic. Most will compost or trash this discard, but you can save it and use it in other recipes!

What happens if I forgot to discard the starter before feeding? ›

If you don't get rid of the excess, eventually you'll have more starter than your feedings can sustain. After a few days, your daily 1/4 cup flour and water won't be enough to sustain your entire jar of starter, and your starter will be slow and sluggish, not much better than discard itself.

Should I discard liquid on top of sourdough starter? ›

A clear liquid on top of a starter that has vigorously risen and fallen and was covered with bubbles (which have subsided) is hooch. If you see hooch on your starter, discard and refeed. A clear liquid on top of a starter that has not vigorously risen and fallen is water separation.

Why discard half of sourdough starter? ›

If you don't discard your sourdough starter, it will grow too big and be unmanageable. Not to mention you will go through an unmentionable amount of flour.

Should I discard liquid on top of sourdough? ›

But if there's a lot of liquid (say, more than half an inch or so), and especially if it's very dark, feel free to pour it off: not because it's “bad,” but because that amount of liquid may change your starter's hydration enough to make a difference in your baking.

What to do with a small amount of sourdough discard? ›

You can always use this discard by directly mixing it into a dough for baking. Your discard, as long as it's in good shape, will leaven any bread dough just as well. The discard is just like a levain you would make for a recipe. The only difference is it's the same makeup as your starter.

Do you have to discard every 12 hours for sourdough starter? ›

Starter that's kept at room temperature is more active than refrigerated starter, and thus needs to be fed more often. Room-temperature starter should be fed every 12 hours (twice a day) using the standard maintenance feeding procedure: discard all but 113g, and feed that 113g starter with 113g each water and flour.

Can you make a new sourdough starter from Discard? ›

Yes. Take a little bit of discard from your jar. Feed it as you would a sourdough starter. Continue this process for a couple of days until the starter is rising and falling predictably again.

Should I stir my sourdough starter between feedings? ›

stir your starter in between feedings - try stirring it twice in between feedings and really give it a chance to get oxygen into the mix. This will help to activate your starter without too much effort.
