After initially maturing in traditional oak casks for approximately 8 years, The Arran Single Malt in this bottling was finished in a selection of Port casks sourced from an artisan producer of this iconic Portuguese fortified wine. The maturation process was monitored under the watchful eye of their Master Distiller, to ensure that the Port casks and the intrinsic character of The Arran Single Malt partnered with each other perfectly. The end result is a combination that's full of charm and rich flavour, and a wonderful way to discover more about the Arran range of Single Malts.
