Refrigerator

Store opened mirin tightly sealed in the refrigerator to maintain quality and prevent spoilage.
Freezer
Not RecommendedNot recommended
Freezing is not recommended for mirin as it can alter its flavor and texture, and its alcohol content may prevent it from freezing solid.
Signs of Spoilage
- Unpleasant or sour odor
- Visible mold growth
- Cloudiness or sediment (if not naturally present)
- Changes in color or texture
- Off-taste
Room Temperature Safety
The 'Danger Zone' for bacterial growth is between 40°F (4°C) and 140°F (60°C).
While mirin's alcohol and sugar content offer some preservation, opened mirin should be refrigerated after use to maintain quality and safety, especially if left out for extended periods within the danger zone.
Safe Handling
Always keep mirin tightly sealed when not in use.
Avoid cross-contamination by using clean utensils when dispensing mirin.
Discard mirin if any signs of spoilage are present.
