FAQs

How much of your sourdough starter should you discard? ›

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.

Over the years, I've found keeping the mixture warm at around 80°F (26°C), and high hydration (100% water to flour in baker's percentages) helps get things started. In addition, while not mandatory, using certain flour also helps increase the chances a starter will take hold quickly (see below).

The starter is a mixture of flour and water that captures wild yeast and bacteria over time, creating a leavening agent for bread. What is this? On the other hand, sourdough discard refers to the portion of the starter that is removed and discarded before feeding the remaining starter during regular maintenance.

The acidity of the sourdough discard helps prevent tough gluten strands from forming. This results in tender and moist baked goods! When discard is coupled with a long ferment, it can aid in digestion and help the nutrients to be more bioavailable to our bodies.

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 I Use 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.

While the age of your starter won't make your bread any better — turns out, only good sourdough practices can do that — it's a link in the long legacy of sourdough, one of the oldest forms of baking that exists. Whether your starter is a week or a decade old, you can become part of that lineage as well.

Place the jar at room temperature for 24 hours, until you begin to see the mixture bubbling up. It is important that you stir the sourdough starter every day in the morning and in the evening.

The longer you go in between feedings, the more acetic acid your starter will develop. This acid creates a more sour flavor.

It can be at room temperature or come directly from the fridge. The texture is less bubbly (if bubbly at all) when compared to fluffy active starter. Sourdough discard is not active enough to make bread dough rise, and despite its name the “discard” does not have to be thrown away.

How do I know if my sourdough discard is ready to use? ›

A jar of sourdough discard serves as an insurance policy against starter death. If you have some discard on hand, remove a spoonful of it and feed it fresh flour and water in a clean jar. You should have a bubbly starter ready to bake with after a couple of feedings, depending on the discard's condition.

Yes, you can give your friend a portion of sourdough discard to start their own sourdough starter, however it's best if your starter is mature (at least 3 months old) when you do this, so that your friend can start baking straight away.

I left my sourdough discard out at room temperature for a few days. Is it okay? As long as your kitchen isn't too warm (I'd say 78°F or higher) your starter/discard will be fine stored at room temperature for at least a few days without feeding. The flavor will get more acidic the longer it sits.

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.

All you need to do is take 20g of the starter you already have and then feed it with 20g of flour and 20g of water (so 1:1:1). Then you'll have a 60g starter, which is considered a smaller amount. You can of course reduce these amounts even further if you wish, but this is a reasonable size to keep waste to a minimum.

A bad sourdough starter may have a strong, putrid, or rotten smell, which is distinctly different from the mildly sour and yeasty aroma of a healthy starter. Your nose knows, toss any starter that smells awful.

If your sourdough starter forms hooch, mix the hooch back into the starter before you discard and feed. The only time I would consider pouring the hooch off your sourdough starter is if it has been stored in the fridge for a long time and the hooch is very dark.

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. You can read more about how to store sourdough discard in the fridge here.
