1990 Monterey County Cabernet

[notawineguy]

I have a bottle of 1990 Monterey County Cabernet Sauvignon Sea Otter Melody from The Monterey Vineyard.

My wife received this as a corporate gift about 10 years ago, and at the time I'm sure it was not a cheap bottle.

Is it worth anything, or should we pop it open to drink? Neither my wife and I are wine drinkers, but we have some close friends who are...

Thanks
