How Long Does Miso Soup Keep in the Fridge?
The answer to this question depends on several factors, including the type of miso used, the presence of additional ingredients, and the temperature of the refrigerator.
Unopened Miso Soup
Unopened miso soup, whether store-bought or homemade, typically has a longer shelf life than opened soup. The unopened container acts as a barrier, preventing contamination and preserving the soup’s freshness.

Homemade Miso Soup: Unopened homemade miso soup can last for 5-7 days.
Opened Miso Soup
Once opened, the shelf life of miso soup decreases due to exposure to air and potential contamination.

Factors Affecting Miso Soup’s Shelf Life
