Question: Is Les Vignerons de Buzet White Wine from 1998 safe to drink?
Answer: Old wine can deteriorate by oxidation plus losing the attractive young grape fruit expression – especially wines produced for earlier consumption. However, generally very old wines are still safe to drink though may be turning to vinegar. If the wine was unclean to begin with it could allow more spoilage due to microbes but unlikely and you can usually spot this when you open the bottle. Your wine from the highly regarded Cooperative of Gascogne in SouthWest France I believe is a blend of Sauvignon Blanc & Semillon. Bottle variation after 25 years is inevitable but you may be in for a delightful rich surprise from the age worthy Semillon component. But if not enough fresh fruit left for you then just make a Kir by adding some creme de cassis or other fruit liqueur. Enjoy.
