As far as Scottish whisky is concerned the time in the bottle is never counted. Unlike wine, once bottled whisky no longer changes (or matures) the age of a whisky is always the age of the youngest component in the blend.
:: Yes this is what I have heard yet when people begin talking of 100 year whisky it always ends up being a bottle that's been around too long.::
As I understand it with the really old matured whiskies - over 60 years say - the amount left in the barrel can be as little as 20% of the original. I was also told in a distillery I visited that these really old whiskies taste dreadful as all the flavour is so concentrated and they are only used for adding to blends as flavouring in very small quantities.
::That makes perfect sense, which argues against going toward overly aged whiskies for drinking straight.::
Oops, sorry drifting off topic there.
