Whisky, unlike many other stored products, develops and gains value as it matures in the cask. Buying casks instead of bottles is a more specialised method. However, it is far more profitable in the long run. Whisky, unlike wine, does not age in the bottle. Scotch Whisky’s flavour will not alter after it is bottled. The age declaration on the bottle relates to how long it has been ageing in the barrel. Even if the bottle is preserved for decades, the ‘age’ does not alter. Once bottled, a 10-year-old whisky will always be a 10-year-old whisky.

In general, the longer the whisky is left in the cask, the greater the quality. As a result, older whiskies attract a greater premium. When you buy casks, you’re getting a product that will improve and develop over time. Furthermore, the tax on whisky in bottles is substantially greater per LPA than on spirit in casks. So because whisky is ageing in a bonded storage, no duty is levied on it, making it incredibly tax effective.
