Harviestoun Ola Dubh 12

Ola Dubh, or ‘Black Oil’ in Gaelic, is masterfully crafted by aging Old Engine Oil in 12-year-old Highland Park whisky casks. This meticulous process infuses the beer with harmonious whisky notes and a roasty, bittersweet, chocolatey finish. It’s an intensive labor of love for the brew team, who fill the mash tuns to the brim with roast barley, pinhead oats, and malted barley, creating a dense and viscous beer that ferments at a slow pace. After at least six months in whisky-soaked casks, the beer takes on the nuanced flavors of the oak, and it’s only deemed ready when their Master Brewer, Stuart, gives his nod of approval.

For those seeking even more intensity, try the 16, 18, and 40-year-aged variations!
