Not sure, but some notes I have say that sealed verjus keeps about a year. I haven't stored it that long before usage, so I can't report more than that. Since it's usually expensive, try by taste if you have some on hand...it likely won't be bad, maybe just not wonderful. Also, here's an article from bonappetit with some history and usage ideas. https://www.bonappetit.com/test-kitchen/ingredients/article/verjus
