Is an old bottle of Bordeaux wine drinkable?

Proper storage is the issue. What grape varities? Give us more information.

Sorry if I didn’t expand more but I was thinking along the lines of a first growth cabernet which is the principal grape of Bordeaux. Prices of these wines are in the stratosphere and would like to know if they are worth it. We have a restaurant here in Toronto which has several on their wine list and a waiter of dubious motives who keeps trying to push them, all the while describing them as “a fine old English gentleman walking off into the distance”. A rather weird description of wine I think, but in any event, one which would certainly indicate that they are past it.

It will almost certainly be past its prime. If not, it would have been almost unbelievably tannic and undrinkable for decades.
