Notes: Every bottle of this extremely limited Ola Dubh 30th Anniversary Ale has been individually numbered. Our ale has been aged for up to six months in first fill sherry butts, formerly used to mature Highland Park's award-winning 30 Year Old Single Malt Scotch Whisky. These hand selected butts add subtle whisky notes to what is already a complex ale with its chocolatey mouthfeel and distinctive bittersweet finish. The high ABV has been deliberately created to stand up to, and blend with, the intensity of flavor created by the infused wood.
