I wish I bought a second bottle of this one right away as it is no longer available in Sweden. One of those bottles that I found myself returning to over and over without drinking any thing else from my collection. The ex-Islay casks is Laphroaig or Bowmore (or both), since Ardmore is also owned by Beam Suntory. When I smelled the glass after it had been empty for a few hours my guess would be Laphroaig casks!
