Beavertown Astro-Nought is an alcohol-free lager under 0.5% ABV, bottom-fermented at the brewery's Enfield, North London site. It was the brewery's first AF lager, arriving after Lazer Crush had established the brand in the IPA corner of the AF market. Where most craft brewers launching a no-alcohol lager aim for clean and neutral, Astro-Nought goes the other direction. The hop profile skews toward citrus rather than the grassy or biscuity notes typical of the style. Tangerine and lemon come through clearly, with a grassy bitterness that is noticeably higher than you'd find in a Heineken 0.0 or Beck's Blue. There is some cereal sweetness in the mid-palate and a lime note that shows briefly before the finish tightens. The body is light, carbonation is brisk, and the pour is pale straw with a slight haze. Astro-Nought makes sense for craft beer fans navigating the AF aisle who find most lagers in the category too watery or too sweet. It's a reasonable option for designated drivers or moderators who want something with a bit more character than the mass-market options. It sells in 330ml cans through supermarkets including Tesco and online via Beavertown's own store. Worth understanding the difference between 0.0% and 0.5% if you're buying for someone who needs the stricter end.
