Sourdough Discard 101 (2024)

FAQs

How do you know how much to discard sourdough starter? ›

Experts recommend feeding a starter twice daily. And at each feeding, you hold onto 1/2 cup of your original starter, discard the rest, and then add its same weight in water and flour. With this schedule, you'd discard almost a cup of sourdough starter every day.

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.

As long as it's not growing mold or bad bacteria, it's safe to use. It won't give you any rise, but it will add flavor! Remember: Sourdough starter and sourdough discard are pretty resilient!

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.

Nope! Once the sourdough starter is established on day 8, all you have to do is just give it flour and water. You no longer need to discard half of it.

Keep feeding your starter, and you'll see normal activity (bubbles) return in a few days. If your starter has a bit of dark liquid on top, it's not dead! It simply means it's hungry and that it's time to feed it. Unless your starter has a pink or orange hue or is beginning to mold, you probably haven't killed it yet.

Do I have to discard my sourdough starter? It would be best if you discarded some portion of your starter each time you feed it unless you want to continue to let it grow. Eventually, you need to discard the used “food” (flour and water) that's been used to sustain your starter during the last fermentation period.

Room temperature sourdough discard should be used, refrigerated, or thrown away after 36-48 hours. Sourdough discard can be kept in the fridge for weeks, BUT it continues to get sourer as time passes.

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.

One note: Don't start using your discard until your starter is really up and running. In other words, if you've just started your starter and it's not yet established, then you shouldn't save that discard. Wait until you have a healthy, active sourdough starter, then keep any discard from routine feedings.

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.

If you've just created your sourdough starter, wait until it's reliably rising and falling each day with signs of fermentation—some rise, bubbles, a progressive sour aroma—before storing discard in your cache.

However, “discard” doesn't necessarily mean “throw out.” A two-to-three day old starter can be used to add amazing flavor and texture to a number of baked goods, even if it is not quite ready to make your dream loaf of sourdough bread.

Can you add sourdough discards together in the same jar? Yes you can add sourdough discards from different days together in the same jar. You just need to make sure you stir it well and you don't leave it sitting in the fridge for too long. Sourdough discard should be used within two weeks.

Remove and discard half of your sourdough starter from the jar. Feed what's left in the jar with equal parts flour and water by weight (1:1:1 feeding ratio). You need a digital kitchen scale for this. Because we all work with different quantities of starters, this 1:1:1 feeding ratio is best understood by example.

As you can see (or smell!), a sourdough starter should have a sour, tangy, and yeasty aroma, with subtle undertones depending on the type of flour used. However, offensive or foul odours such as rancid, putrid, or mouldy smells are signs that something has gone wrong with the starter.

If you didn't discard a portion of your starter each time you feed it, two things would happen: Your starter would grow to an enormous, unmanageable size. Your starter would likely become more and more inhospitable to the bacteria and yeast we want as the mixture would become ever more acidic.

Kept in the fridge, sourdough discard will last several weeks. Similar principles apply to sourdough discard as they do to starter; black liquid on top is totally fine, but streaks of pink or orange mean that it's likely contaminated and should be tossed.

When in the process of making a new sourdough starter you should not save the sourdough discard. During the beginning stages of making a starter it is more susceptible to mold and other bad bacteria. You will want to wait until the starter is doubling in size and bubbling with each feeding.
