Harviestoun Brewery Ola Dubh (Cask)

Ola Dubh, meaning ‘Black Oil’ in Gaelic, is craftily created by taking our Old Engine Oil and maturing it in 12 year old Highland Park whisky casks. The process is far from simple, but the result is a beautiful brew with complimentary whisky notes and a chocolate, roasty and bittersweet aftertaste. All thanks to the labour of love of our master brewers. Ola Dubh is a labour of love. Everything about it is extreme. The brew team fill the mash tuns to the brim with roast barley, pinhead oats and malted barley. It ferments more slowly as the the yeast struggles to move around in such a viscous beer! The base beer is Old Engine Oil which they then put into Highland Park Whisky casks and it stays there for at least 6 months. During this time the flavours from the wood enter the beer to produce Ola Dubh. It is ready only when our Master Brewer, Stuart, deems it ready! Try the range! 16 & 18 & 40 year old now available.
