Unopened, refrigerated at 28 - 32
° F, non-pasteurized caviar will keep its quality for three weeks to a month; once opened, it should be consumed within a day or two. Pasteurized caviar, as long as the container remains sealed, will last a year and should be consumed within ten days once opened.
I doubt the Costco sells unpasteurized caviar.
