FAQs

How much of your sourdough starter should you discard? ›

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.

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.

Sourdough discard recipes not only reduce waste but also offer health benefits, making them a wonderful addition to a balanced diet. The fermentation process of the sourdough starter increases the availability of certain nutrients and can help improve digestion.

The most common feeding ratio is 1:1:1 (sourdough starter: flour: water). This is also known as a 100% hydration starter. For example, let's say you have 40 g of sourdough starter in a jar. To feed it, you'll add 40 g of flour + 40 g of water.

Sourdough discard only lasts a day or two at room temperature. As such, it is best to keep your discard in the fridge, where it will last for up to one week. Of course, you can only rely on it lasting that long if you store it correctly.

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.

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.

Can sourdough discard be used as starter? While sourdough discard can't replace an active starter in a recipe that relies on a robust leavening agent, it can be revitalized and used to create a new starter.

You can use 1-2 week old discard in “discard recipes”… think cookies, brownies, muffins, non-yeast breads, tortillas (pretty much anything that doesn't require active starter (aka wild yeast). I have TONS in my digital cookbook if you need some good recipes.

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.

Can I use Day 4 sourdough discard? ›

The longer the discard sits in your refrigerator, the more fermented and “sour” it gets. I don't like to use discard that is more than one week old in discard recipes . After about a week, the discard can become very sour and impact the flavor of the discard recipe.

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.

If you do not have whole wheat flour, just use all purpose flour instead. The starter will be fine. I switch to all purpose flour for the feedings because it's reliable, inexpensive and practical for everyday baking (remember, a portion of your starter is removed, discarded, or used for something else).

Does it matter if my starter is thick or thin, you ask? Nope! Thick and thin starters are both full of wild yeasts and bacteria which is what your bread is begging for. The viscosity of your starter is really just a personal preference because thick and thin starters will both make bread.

Compared to whole wheat flour, rye flour is said to be the most nutrient- and amylase-dense option for a sourdough starter. Overall, it has a lower gluten protein content than wheat flour, which means it produces slack, sticky, and dense doughs.

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.

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.

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.

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. You can continue to add more discard to the jar just pour it in and give it a stir before placing it back in the fridge covered.
