Castello di Farnetella Nero di Nubi Toscana 1993

The big question is whether an old wine should be drunk.
Quality systematically declines around 20 years.
Be aware that it is quite possible when you open an old wine that it is no longer ready to drink.
Can be used purely as decoration and enjoy the antiquity of the bottle.

Simple supermarket wines will never increase in value.
On the other hand, a quality wine will increase in value.
