Named 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. Harviestoun’s original master brewer Ken Brooker spent much of his early life crafting wooden design prototypes for Ford. Naturally then this thick, black, gloopy beer, reminded Ken of car engine oil, so he named it in honour of his second love, the internal combustion engine. Outrageously smooth this strong dark beer with its chocolaty flavour leaves a bittersweet aftertaste to savour. Best served slightly colder than your normal porter. Harviestoun Old Engine Oil won a Silver Medal at the World Beer Awards 2015 in the category United Kingdom - Porter.
