Browse our whisky database by the age of the whisky. The 'age' of a whisky is the time it spent in the 'cask' before being bottled. The longer a whisky remains in the cask, the more flavour it will acquire and the less spirit will remain.
The age of a whisk(e)y is determined by the length of time it has spent in the cask before being bottled. Once the whisk(e)y has been bottled the aging process stops. A whisk(e)y bottled at 10 years old will always be a 10 year old whisk(e)y even in a hundred years. By then the vintage of the whisk(e)y would still make it a rare and valuable item.
When dealing especially with blends, but also with single malts, some of the whiskies may be older than the stated age. However none of the whiskies will be younger.
