Pantry storage

Does miso need to be refrigerated?

Before opening, follow the label: Hikari Miso says a cool, dark pantry works for a sealed package. After opening, yes. Hikari Miso's instruction is plain: once the package is opened it should be refrigerated, and the date on the tub marks peak flavor rather than expiry.

These times are a guide, not a safety guarantee, and a label that says to refrigerate comes first.

Unopened and opened

Unopened and opened packages keep for different times. These are the times the source gives.

Unopened
Follow the package: Hikari Miso says to keep a sealed package somewhere cool, dark and dry, such as a pantry below 75°F (24°C), or in the fridge in a hot climate. Source: How to Store Miso Paste, Hikari Miso (opens in a new tab)
After opening
About 1 year in the fridge, counted from the day you bought it, per USDA FoodKeeper; Hikari Miso gives no separate time once it is open
Where to keep it once open
Refrigerator. Refrigeration is required here, not optional.

Sources and limits

The after-opening time runs from the day you opened it, not from the date printed on the package, so write that day down. Well Stockd doesn’t know when your package was made, bought or opened: follow the package directions, keep it in the fridge at 40°F or below once it’s open, and check the official listing when food safety is in question.

The storage times above are quoted from the sources below. They’re a guide, not a safety guarantee: quality varies with packaging, temperature and how the package is handled between uses. Nothing here overrides a label that says to refrigerate. This page was last updated .
