Pistonhead is Brutal Brewing's lifestyle sub-brand, and Flat Tire is the one most AF drinkers will know. It's a dry-hopped lager at 0.5% ABV, made with Centennial, Magnum, and Mosaic hops added late in the process for aroma rather than bitterness. The malt bill uses a combination of Pilsner, Münchener, and Light Caramel malts, which gives it a fuller body than many low-ABV lagers manage. In the glass it pours hazy amber — not filtered bright like a standard lager — with a head that doesn't stick around long. The aroma is the high point: tropical fruit from the Mosaic, some pine and flowers from the Centennial, and a soft caramel note underneath. The first few sips carry that tropical character well, with papaya and citrus upfront before the malt base takes over. The mouthfeel is notably thick for a 0.5% beer, which helps it feel more substantial. The honest caveat is that the interesting flavour does fade as you drink through the can. By the end you're in fairly generic malt territory. But as a gateway lager for people who want something with actual hop character at near-zero ABV, it's one of the more convincing efforts around.
