My town has one of the oldest underground wine cellars in Europe with some bottles up to 300 years old. I talked to somebody maintaining the wine cellar and part of the cork replacement procedure that happens about every 50 years is to taste the wine - just a drop though. Apparently it’s pretty awful. His colleague said “You have to taste your way up to one of these!” which sounds like bullshit to me. I bet it doesn’t get better after 1700 more years.
