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.
