In my dull moment (perhaps inspirational?), I was thinking if this is at all possible? Take say 5 bottles of 'early' single malt and put it in a small cask. Place it in a cool dark place for several years. Can you say that the aging process continues?
Assuming that you can fabricate a small cask made of the same material as the ones used by the distilleries. In fact, if this method works, some enterprising person may sell this small casks for home use?
The normal bottling process is simple. From cask to bottle, done! Some do filter the malt before bottling but this does not change the chemical makeup.
So, malt makers expert out there, what do you think?
