THE SINGELTON Of Dufftown 25 Year. Aged in ex-Bourbon casks in the Dufftown Distillery in Dufftown, Speyside, this single malt pours as a light orange gold with a nose that is smooth and round, subtly hinting at notes of tropical fruit. The palate proves to be spicier and even more tropical, with layers of pears, passionfruit and even pineapple. The finish is lengthy and designed to be approachable, ideal for introducing new aficionados to the world of scotch.
