Like a cork from a very old bottle of wine or port to be extracted, there is a good chance that this with a normal corkscrew will crumble.
Château Dauzac Margaux
A good quality wine can be drunk into old age. You never know with absolute certainty or a wine still drinkable. That depends on a lot of factors. When the wine reaches the twenty years of age or older, only the best yet with it, and afterwards increases the risk.
An old wine tasting also has its emotional side: you relive as if it were a piece of history.
