Where is the Best Place to Store Miso Paste?

Looking for a great spot to store your miso paste? Let’s talk about these three options:

  • Dark and cool place
  • Refrigerator
  • Freezer

Store at Room Temperature

You can store miso paste at room temperature. The best place is somewhere dark and cool, like kitchen cabinets, and avoid direct sunlight.

Storing it in a hot and humid environment can lead to a decline in taste or even mold growth. To maintain its quality, ensure that the storage temperature is below 20°C (68°F).

However, be careful if you use the low-salt content type or processed variety like the one containing soup stock, as it may spoil at room temperature.

Here are the main points of storing at room temperature.

  • Unopened miso paste can be stored at room temperature
  • The best place is a cool and dark place without direct sunlight
  • The temperature should be below 20C/68F
  • Processed miso paste may not be safe to store at room temperature

Does Miso Paste Need to Be Refrigerated?

If you live in a hot climate, refrigerating your miso paste is the best way to maintain its flavor and quality. You should keep miso paste in an airtight container and refrigerate to preserve its freshness.

Given my region’s hot and humid summers, I store my miso paste in the fridge all year. This way, it can maintain its freshness for a year or even longer.

Can You Freeze Miso Paste?

Yes, you can!

Another way to preserve the flavor of delicious miso paste is by freezing it. Kept in your freezer, this savory seasoning can stay at its quality for up to a year as no bacteria grow inside the freezer.

Since miso paste contains many ingredients besides water, it does not freeze like ice cubes, and you can use it right out of the freezer (no need to thaw).

Helpful Tips for Storing Miso Paste

  • Once opened, the miso paste will oxidize when exposed to the air, but covering the surface of the miso paste with plastic wrap and sealing it tightly will help keep the quality.
  • Scoop your miso paste with dry and clean utensils (when you use it for cooking) – moisture creates an environment for bacteria growth.

How Long Does Miso Paste Last?

Miso paste has a long shelf life, like 3 months to 12 months, because of its high salt content, and generally doesn’t go bad. Especially unopened miso paste can be stored at room temperature for more than a couple of months because bacteria in the air do not enter.
