“Punk AF” is a low-alcohol (0.5%) version of Brewdog’s full-strength “Punk” IPA.Rather than remove the alcohol after fermentation, Brewdog produce a wort that’s low in fermentable sugars to make its Punk AF Beer. The grain bill includes wheat and flaked oats alongside Caramalt and Munich malts. This is complemented by eight varieties of hops – Cascade, Chinook, Citra, Mosaic, Nelson Sauvin and Simcoe as well as two types not featured in the original Punk, Hüll Melon and Ahtanum. Versus the 5.6% version of Punk IPA, there’s 68% fewer calories – 50 compared to 150 in a 330ml bottle. That hop focus is evident in the aroma. It begins skunky and spicy with pine, citrus and tropical fruits coming out as the head settles. As it warms, a weak aroma of caramalt is backed by sweet and sticky mango.
