Whisky Myths: Whisky ages in the bottle, right?
Wrong! If you buy an 18-year-old bottle of whisky, it will forever remain an 18-year-old, regardless of how long you keep it for. This is because the ageing process occurs in a cask (or casks) and is considered complete prior to bottling.
Value over time, however, is another issue entirely. When you read of older bottles fetching eye-watering sums at auction, this is due to provenance and other factors of perceived value. It is not because the whisky itself has aged more.
