Jet Black Heart is BrewDog's milk stout, a full-bodied beer at just 4.7% ABV that delivers surprising depth. Roasted malt, coffee and chocolate dominate the flavour profile, bound together by the creamy sweetness characteristic of the style. The texture is smooth and silky, making this a remarkably approachable stout despite its richness.

The palate shows subtle toffee and caramel notes leading to a gentle, clean bitterness that prevents the beer from becoming cloying. In blind tastings, more than half of participants preferred it to traditional Irish stouts. Jet Black Heart suits drinkers seeking a full-flavoured stout without the alcohol punch of higher-ABV alternatives.
