Harviestoun is a relatively young brewery (founded in 1985) located in Scotland which features amongst their portfolio of beers a series named Ola Dubh, which translates “Black Oil”. From the Harviestoun website itself:
Ola Dubh (or ‘Black Oil’) is a collaboration between Harviestoun Brewery and Highland Park, Distiller of the Year. It is based on Harviestoun’s award-winning Old Engine Oil. With more than a stylistic nod to the classic Imperial Porters (and Stouts) of the nineteenth century, this deliciously rich, dark, 8% a.b.v. beer is the first ale to be aged in malt whisky casks from a named distillery and, with traceable casks and numbered bottles, the first with genuine provenance.
Ola Dubh is currently available in five variants based on the age of the whisky previously stored in each cask: 12 yr., 16 yr., 18 yr., 30 yr. and 40 yr. As we already carry the 12 yr. and 18 yr. versions of Highland Park, I picked the Ola Dubh Special Reserve 12 and 18 and will be reviewing both in this post.
Ola Dubh Special Reserve 12 pours nearly black, with a very thin, almost non-existent head. The aroma is nutty, and that carries over to the taste as well. Aside from being nutty, there is a light hoppiness and an oily texture with a hint of peat smoke in the finish. Overall, not a session brew, or even an everyday brew, but definitely something to be savored and enjoyed when looking for something different.
Ola Dubh Special Reserve 18 is a slightly different animal. While it also pours nearly black with a thin head, that is the end of the similarities. The aroma is slightly astringent, with a hint of peat smoke. The taste is significantly less oily and viscous than the 12, with a warmer feel. There is nothing resembling hops in the taste, but there is plenty of peat smoke, and a slight sweetness in the finish – I’m not sure if that’s from residual Scotch in the cask wood or from the roasted malt used in the beer. Again, much like the 12, this isn’t something I would drink daily, but rather, something of a treat.
Considering these are the first whisky cask-aged beers I’ve tried, I am a novice when it comes to this type of beer (which has recently grown in popularity amongst American brewers as well). That said, I enjoyed both beers and won’t hesitate to buy them again.
