12 Yo Highland Park very reliable good Malt. Beware the Supermarket 10 Yo, according to Highland Park tasting room staff this is really blended for mixing ( most Single Malts are blended unless they are Single Cask ) IMHO 12 Yo best for drinking, 15 Yo also good but not worth premium IMV 18 Yo is worth extra as a treat, but a LOT extra ! Like Treble the 12 Yo price
