How Long Does Miso Paste Last in the Fridge?

Unopened miso paste

An unopened container of miso paste can last up to a year in the refrigerator, even a few months after the expiration date, provided it is stored in a cool, dark place. The fermentation process, which is crucial to creating miso paste, acts as a natural preservative, contributing to its extended shelf life.

Opened miso paste

Once opened, miso paste can last between six months and a year in the refrigerator, depending on the type of miso and how it’s stored. Proper storage techniques, which we’ll discuss later in this article, are essential to preserving the quality and flavor of your miso paste.

Factors affecting shelf life

Type of miso: Different types of miso paste have varying shelf lives due to their unique fermentation processes and ingredient compositions. Generally, lighter miso pastes (such as white or yellow miso) have shorter shelf lives than darker miso pastes (like red miso).

Preservation methods: Using a clean spoon when scooping miso paste, sealing the container tightly, and storing it in the refrigerator can help extend its shelf life.
