And I find that Sauternes keeps slightly longer in the refrigerator than other wines: at least four to five days, sometimes longer.

How long can you keep Sauternes wine?

Jeb, for wines up to about 30 years old (meaning the mid-to-late 1980s), they should be fine for a minimum of a week in the fridge, and wouldn't be surprised if they go two weeks but you might see an acidic streak coming out.

Can Sauterne go bad?

Yes, unopened and even properly stored wines can go bad. There are some ways to tell if the unopened wine might be bad just by using your eyes! ... However, there are always exceptions in the world of wine, as some ageable wines like Sauternes do come in clear bottles.
