The Knockdhu Distillery, in Knock in Aberdeenshire, although on the border of Speyside, is a Highland whisky, a fact that perhaps delivers a surprise when tasting anCnoc. It produces a light, intriguing and thoroughly modern whisky to this day. Wholly maturing anCnoc whiskies in American bourbon casks allows the characteristic intense citrus notes to shine through.anCnoc 16 year old has been bottled in its most natural form at 46%abv as it is neither chill-filtered nor coloured. As a result, it may develop a light haze with the addition of water or if kept at a cold temperature. This haze is a natural characteristic of whisky that is non chill-filtered.
