We went to Islay, Jura and Arran for holiday this summer. Visited every distillery and did 3 tours (Bunnahabhain, Lagavulin & Arran).
I was surprised that of the 3 tastings (and another at Kilchoman), I actually preferred the youngest 10yo Arran. Probably the easiest drinking - light, honeyed tones - but subtly complex presumably as it is not chill filtered.
Other favourites I brought back were a quarter cask of Laphroaig and a Sherry cask Bunnahabhain (toitteach a dha). Sadly only a drop of each left but I'm sure more will arrive in a few weeks!
