We just found a bottle of 1983 Chateau St. Jean brut Blanc de blanc sparkling wine hiding out in the back of a closet.
Is this still drinkable?
Is it aged and valueable now?
Or is it just a bottle of vinegar?
We don't recall when or how we got it, but it's been in the house since the early 80's!! Yikes!
Any advice would be much appreciated. Suggestions of some wine forums where we could go for advice might be a help too.
