Harviestoun Ola Dubh 18 Stout is a unique, deep black beer that fully deserves its name - "black oil" in Gaelic. This exceptional stout is matured for at least six months in 18-year-old Highland Park whisky casks, giving it complex flavours 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 as it matures. 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 combination of beer and whisky.
