Do I have a wine or a salad dressing?

[Jerry D Mead]

There's a chance that BV Cabernet is still good, if it has had especially good (constant cool temperature) storage.

Thirty years is a long time as far as life expectancy goes for most California reds. If there aren't too many of them, list a few more and we'll try to make some educated guesses.

Your BV is not going to get any better...no matter what...so plan to open it with friends soon...but have a back-up bottle of something current so you won't go thirsty if it is over the hill.
