Whisky Ardbeg Wee Beastie 5 Year Old. Ardbeg's Wee Beastie is a youthful single malt drawn from a combination of ex-bourbon and Oloroso sherry casks, bottled up at five years of age. Peaty notes sit at the fore for this one, with oak somewhat taking a back seat, since... Well, y'know, it didn't stay inside those casks for too long. However, don't mistake that for meaning Wee Beastie is an uncomplex expression. It still packs a satisfying flavour profile that should impress many of the Ardbeg aficionados out there.
