- Keep refrigerated and tightly sealed.
- Storage time shown is for best quality only - after that, the miso's texture, color or flavor may change, but in most cases, it will still be safe to consume if it has been kept continuously refrigerated.
- If miso develops an off odor, flavor or appearance, it should be discarded for quality purposes; if mold appears, discard the entire product.
- Best By, Best if Used By, and Use By dates on commercially packaged foods sold in the United States represent the manufacturer's estimate of how long the product will remain at peak quality - in most cases, the opened miso will still be safe to consume after that date, as long as it has been stored properly and kept continuously refrigerated after opening.
