How long can you keep sourdough discard in the fridge? This is a common question among those who are new to sourdough baking or those who regularly maintain a sourdough starter. Sourdough discard is the portion of the starter that is removed before feeding, and while it might seem like something to toss out, it can actually be stored and used in various recipes.
However, proper storage is essential to ensure that the discard remains safe and beneficial for future use. In this article, we’ll explore the best practices for storing sourdough discard, how long it can be kept in the fridge, and how to determine if it’s still good to use.
What is Sourdough Discard?
Before addressing how long can you keep sourdough discard in the fridge, it’s important to understand what sourdough discard actually is. When maintaining a sourdough starter, regular feedings are necessary to keep the yeast and bacteria active and healthy. This process involves discarding a portion of the starter before adding fresh flour and water. This removed portion is known as sourdough discard. While it may no longer be ideal for baking bread due to its depleted yeast activity, it still contains beneficial bacteria and can be used in a variety of other recipes.
How Long Can You Keep Sourdough Discard in the Fridge? The Basics
How long can you keep sourdough discard in the fridge? The answer can vary depending on how it is stored and the condition of the discard when it was placed in the fridge. Generally, sourdough discard can be kept in the refrigerator for up to one week.
After this period, the discard may begin to lose its vitality, develop off flavors, or become contaminated with harmful bacteria.
1. Factors Affecting Shelf Life
Several factors influence how long you can keep sourdough discard in the fridge:
- Temperature: The colder the fridge, the longer the discard will last. Keeping the discard in the coldest part of the fridge can help extend its shelf life.
- Container: Storing sourdough discard in an airtight container helps prevent contamination and slows down the fermentation process, which can extend its shelf life.
- Frequency of Use: If you regularly use and refresh your discard by mixing in new discard, it may last longer than one week.
2. Visual and Sensory Cues
To determine how long can you keep sourdough discard in the fridge, you should also rely on visual and sensory cues. Discard that is still good to use should have a pleasant, tangy smell and a smooth consistency. If the discard develops a foul odor, visible mold, or an unusual texture, it’s best to discard it.
How to Store Sourdough Discard in the Fridge ?
Proper storage is key to maximizing the shelf life of sourdough discard. Here’s a guide on how to store it effectively:
1. Use an Airtight Container
To answer how long can you keep sourdough discard in the fridge, one of the most important factors is using the right container. An airtight container prevents air from entering, which can lead to spoilage. Glass jars with tight-fitting lids are ideal for this purpose, as they are non-reactive and can be easily sterilized.
2. Label the Container
It’s important to label the container with the date when the discard was added to the fridge. This helps you keep track of how long it has been stored and ensures you use it within the recommended time frame.
3. Store in the Coldest Part of the Fridge
For optimal storage, place the container of sourdough discard in the coldest part of your fridge. This could be the back of the bottom shelf, where the temperature is more stable and less affected by frequent door openings.
Extending the Shelf Life of Sourdough Discard
If you find yourself with more sourdough discard than you can use within a week, there are methods to extend its shelf life beyond refrigeration.
1. Freezing Sourdough Discard
Freezing is an effective way to preserve sourdough discard for an extended period. To freeze, simply place the discard in a freezer-safe container or a resealable freezer bag. Make sure to label the container with the date of freezing. Frozen sourdough discard can be stored for up to three months without significant loss of quality.
When you’re ready to use the frozen discard, thaw it in the refrigerator overnight. Once thawed, it can be used in any recipe that calls for sourdough discard.
2. Dehydrating Sourdough Discard
Another method to extend how long you can keep sourdough discard in the fridge is by dehydrating it. Dehydrating removes moisture, making the discard shelf-stable for months. Spread the discard thinly on a parchment-lined baking sheet and place it in a low oven (around 150°F) or a dehydrator until completely dry. Once dried, the discard can be crumbled into flakes and stored in an airtight container in a cool, dry place. To rehydrate, simply mix the flakes with water until you achieve the desired consistency.
How to Tell If Sourdough Discard Has Gone Bad
Even with proper storage, sourdough discard will eventually spoil. Here’s how to tell if your sourdough discard is no longer safe to use:
1. Smell Test
A healthy sourdough discard should have a tangy, slightly acidic smell. If the discard emits a foul, rotten, or overly sour odor, it’s a sign that it has gone bad and should be discarded.
2. Mold Growth
Mold is an obvious indicator that sourdough discard is spoiled. If you see any signs of mold—whether it’s green, white, or black—on the surface or around the edges, it’s best to throw out the entire batch.
3. Unusual Texture
The texture of sourdough discard should be smooth and slightly viscous. If it becomes excessively watery, slimy, or gritty, it may have spoiled. Additionally, if you notice any separation of liquid on the top (known as “hooch”), it’s a sign that the discard is beginning to degrade. While hooch itself isn’t harmful and can be stirred back in, it indicates that the discard is nearing the end of its usable life.

Reducing food waste is a key component of sustainable living, and finding ways to utilize sourdough discard instead of throwing it away contributes to this effort.
1. Reducing Food Waste
By properly storing sourdough discard and using it in various recipes, you help reduce food waste in your home. Discarding sourdough that can still be used is wasteful, especially when it can be transformed into nutritious and delicious foods. This practice aligns with a zero-waste approach to cooking, where every part of an ingredient is utilized to its fullest potential.
2. Supporting Sustainable Practices
When you extend the shelf life of sourdough discard by freezing or dehydrating it, you’re not only reducing waste but also supporting sustainable practices in your kitchen. These methods ensure that you can use your sourdough discard over a longer period, minimizing the need for frequent baking sessions and reducing your overall environmental footprint.
3. Ethical Consumption
Utilizing sourdough discard is an ethical choice that reflects respect for the resources that go into producing food. Flour, water, and energy are required to maintain a sourdough starter, and wasting the discard undermines the value of these resources. By storing and using sourdough discard responsibly, you make a conscious decision to honor the effort and materials involved in food production.
