Caol Ila is a fascinating distillery. Easily the largest facility on Islay, because it's mostly buried by Diageo the general public has almost no awareness of the name. The people I meet in bars who can even pronounce Caol Ila are few and far between.
Yet since so much of the spirit gets sold off to independent bottlers (although that situation seems vaguely precarious, and a couple years ago there were rumors it might end or at least curtail), there are myriad presentations of Caol Ila, some of which are simply stunning.
