Harviestoun Ola Dubh 18 Stout is a unique, deep black beer that fully deserves its name – "Black Oil" in Gaelic. This exceptional stout matures for at least six months in 18-year-old Highland Park whisky barrels, giving it complex aromas of oak and whisky. The base is the legendary Old Engine Oil, a thick and full-bodied beer that develops intense notes of chocolate, roasted malt, and a bittersweet depth through the aging process. With every sip, you can feel the loving craftsmanship that has gone into this beer. It is a true masterpiece for connoisseurs who appreciate the perfect fusion of beer and whisky.
