Speyside Single Malt Scotch Whisky
Just like Strathisla, Glen Grant, Mortlach, Dalmore and Macallan from the same era, Glenlivet could age phenomenally well. Combine this with the truly old style pre-war production methods and the out of this galaxy quality of the sherry casks they were using, and you get whisky like this. You just gotta try it to get it.
