Do You Have to Discard Sourdough Starter Daily? ›

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.

Refrigerator storage: Feed once a week

Measure out 113g (1/2 cup) of the starter; discard the rest (or bake something with it).

Although you need an active, well-maintained starter for certain artisan breads, you can still make tasty bread with a sluggish, slow starter so you don't have to discard sourdough starter daily. In fact, many of my favorite sourdough bread recipes use discard for flavoring to give bread that classic tang.

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.

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.

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.

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.

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.

Can you use active starter in place of discard starter in a recipe? Absolutely you can! Active starter can be used in the same way as sourdough discard in sweet or savory baking. You can add active sourdough starter to any recipe you would add discard to following the same calculation.

A starter stored in the fridge can be fed once a week. If you plan to use it often, you can store it for up to two months without feeding. When you want to use the starter again, remove it from the fridge for a few hours, then feed it every 12 hours for 36 hours before you make bread with it.

Why is my sourdough starter bubbling but not rising? ›

If your starter gets completely covered on top with bubbles but does not rise, it is healthy but may just be a wet mix. Try reducing the water in your next feeding and see if you have different results. Also, the type of flour you are using can impede the rise of your starter.

I wouldn't go more than 24 hours without feeding a very young sourdough starter (it may survive longer than this unfed however you will leave it open to the risk of mold). Mature sourdough starter aged more than 6 months old should be able to survive unfed on the counter for around 3-4 days without any risk of mold.

If you are going to feed your starter, let's say it is out of the fridge, you give it flour and water and stir it up really well. You do not want to instantly put it back in the fridge, even if you are not planning to use it.

One of the amazing benefits of sourdough discard is that you can use it to create new starters, which are known as levains. These off-shoots from the mother starter can be used to experiment with different types of flour or given as a gift – there's nothing quite like sharing an entire ecosystem with your loved ones.

Discarding half is wayyyy LESS wasteful than keeping it around or “sharing” the other half with a friend because… The sourdough starter is not a viable starter until 3 to 5 days old and sometimes longer. It takes that long for the organism balance to get established.

I would say the best way to differentiate between discard and active starter is that active starter is starter that has doubled and peaked whereas discard is any starter that is not the main starter and is not being used in an active sourdough recipe as a leavening agent.

Dried sourdough starter lasts indefinitely, and can be brought back to life with water and flour when you're finally ready to bake again.

Yes, you can overfeed your sourdough starter. Audrey explains: “Every time you add more flour and water, you are depleting the existing population of natural bacteria and yeast.” If you keep adding more and more, eventually you'll dilute the starter so much that you'll just have flour and water.

If your sourdough starter is left too long it gets hungry and exhausted. You will know because it will have doubled and then the air pockets start to collapse and the mix deflates. This can happen at any temperature, but it will be slower to occur in cool environments and much faster in warmer.
