I do have a bottle featured in my liquor cabinet. My cousin lived in Ireland for 5 years. My favorite Irish Whiskey is Bushmill. She got me an 18 yr (Not sold in North America) with my name imprinted on the label. I've had it for 3 years and have yet to crack it open. I probably never will
Anytime I want to get a special bottle for events, I end up wanting to drink from it more often, so I gave up on that concept. For the most part I always make sure to keep a smoky drink around (Laphroaig or Ardbeg) and a sherry one (Dalmore or Glenfiddich).
My favourite ones would be Ardbeg Uigeadail and Bowmore 15.
