Production & Heritage

Harviestoun Brewery operates out of Alva, a small town at the foot of the Ochil Hills in central Scotland. Old Engine Oil is brewed from a grain bill of pale malt, roasted barley, and malted oats, then hopped with a blend of East Kent Goldings, Fuggles, and Galena. The defining production technique is a super-high-temperature mash, which makes the wort less fermentable and leaves behind elevated residual sugars. The result is a beer with the present gravity, mouthfeel, and viscosity of a barley wine — typically brewed at 8.5% ABV or above — but at a far more sessionable 6.0%. The oats serve a critical role, smoothing out the bitterness that roasted barley would otherwise produce and contributing to the beer's signature velvety texture.

Tasting Notes

Aroma: A wave of roasted coffee and dark chocolate leads, followed by a subtle rummy sweetness and hints of brown sugar. The nose is inviting without being aggressive, carrying warmth rather than sharp roast.

Taste: The entry is dominated by rich caramel and roast malt, giving way to buttered toffee and espresso at mid-palate. A mild cherry-like fruitiness surfaces within the residual sweetness, adding complexity to the otherwise dark, roasty profile. Brown sugar and earthy hop bitterness provide structure without overwhelming the malt backbone.

Finish: Long and creamy, with lingering dark chocolate and a faint coffee bitterness that slowly fades. The oat-driven mouthfeel keeps everything smooth through the final swallow, leaving a clean but satisfying roasted aftertaste.

How to Drink Old Engine Oil

Old Engine Oil is best served at cellar temperature, around 50–55°F (10–13°C), in a tulip glass or snifter to concentrate its complex aromas. Pouring too cold suppresses the toffee and chocolate nuances that define the beer. For a Black Velvet variation, try blending it with dry sparkling cider — the dark malt plays beautifully against effervescence and acidity. In a Beer Float, the creamy body and coffee-chocolate notes pair naturally with vanilla ice cream for a rich dessert drink. As a foundation for a Stout Flip, shake it with a whole egg, a touch of simple syrup, and a pinch of nutmeg for a frothy, indulgent nightcap.
