Does Wasabi Ever Go Bad?
Yes, wasabi can go bad over time. Once opened, the freshness and quality of wasabi will gradually deteriorate. It is best to consume wasabi within one to two months of opening or by the expiration date if unopened, stored properly in the refrigerator, and sealed tightly. Over time, the wasabi can lose its flavor, texture, and potency as it ages. To ensure the best quality and freshness, it is recommended to only buy wasabi from a reliable source.
