What Is Sourdough Discard?

Sourdough discard consists of flour, water, wild yeast, and bacteria, similar to a sourdough starter.

Bakers often incorporate discard into pancakes, crackers, and other baked goods to reduce waste and add a distinct tangy flavor.

Factors Affecting the Shelf Life of Sourdough Discard

Several factors influence how long sourdough discard remains good:

• Storage Conditions: The temperature and environment where you store your discard significantly impact its shelf life. Typically, discard lasts longer in cooler environments, such as the refrigerator or freezer. Discover more about properly storing sourdough discard to ensure it stays fresh.
• Type of Flour Used: Whole grain flours tend to spoil faster than white flours because they contain more natural oils. These oils can go rancid if not stored properly.
• Hydration Level: A higher hydration level can make the discard more prone to mold growth, while a lower hydration level can extend its life.
• Presence of Salt or Additives: Adding salt or other preservatives can inhibit the growth of unwanted bacteria and yeast, extending the shelf life of the discard.
