Famed for the great but more common Bitter and Twisted and Schiehallion, we believe Harviestoun's best beers are their darker Porters and Stouts. It's either in the pure Scottish water of the Ochi hills or something in the Scottish Malts, either way we love 'em. Their icon and mascot is a "fractious mouse" which appears on each of the labels and was apparently the inspiration for the first brew. Ola Dubh (‘Black Oil’) is the unique lovechild of Harviestoun Brewery and Highland Park distillery and a development of their Engine Oil Porter, this deliciously rich, dark, 8% a.b.v. beer is the first beer to be aged in malt whisky casks from a named distillery. Retaining the gloopy appearance of used motor oil, it is deep dark brown, dense and oily. On the nose there are notes of truffle oil and cocoa as well as faint smoke and heathery peat from the whisky casks. Although lighter in body than its appearance suggests, the finish is burnt and bitter with notes of late hop characters and fruity smoky tartness. Harviestoun Ola Dubh 12 year old won United Kingdom's Best Wood Aged Beer at the World Beer Awards 2015.
