but only after it has aged

beer and whisky dont mature like wine does. Its a myth

whiskey does, it takes on flavours from the cask it's stored in and sometimes the air outside it.
Of course with whiskey ever more being stored in large steel vats rather than oak casks that effect is often lost.

not in a bottle was what i meant.

If you have a glenlivet 10 year old , which you baught in 1980, it is still a 10 year old whisky - not a 38 year old one.

in the EU by law it has to be aged in a cask for at least 3 years, in scotland, to be legally called scotch whisky

Red or white wine, max. 2 decilitre, or Becherovka, Demänovka, herbaceous products of Czech and Slovak Republic. :)
