leach Peated Islay Malt. The Ileach Peated Malt is sourced from an undisclosed distillery on Islay, so that narrows it down to being either, Ardbeg, Bowmore, Bruichladdich, Bunnahabhain, Caol Ila, Kilchoman, Lagavulin or Laphroaig. Ileach is an independent bottling from the good people at the Highland and Island Scotch Whisky Company (based in Glasgow).
