Fungtn is a UK-based craft beer brand that has carved out a distinctive niche at the intersection of functional wellness and brewing. Founded with a mission to disrupt the craft beer space, Fungtn brews alcohol-free, vegan, and gluten-free beers infused with adaptogenic and medicinal mushrooms, including lion's mane, reishi, and chaga. The brand describes its approach as creating a more mindful beer experience that goes beyond simply reducing alcohol content. Fungtn's portfolio is built around functional brewing, combining traditional brewing techniques with superfood mushroom ingredients to deliver what the brand calls a "functional finish." The range is entirely alcohol-free and crafted to appeal to health-conscious beer drinkers who do not want to compromise on flavour or craft credentials. Each beer is brewed with a specific mushroom variety chosen for its reputed adaptogenic properties, giving the range a clear wellness-forward identity within the non-alcoholic beer category. Among Fungtn's notable offerings is the Lion's Mane IPA, a hop-forward non-alcoholic IPA brewed with lion's mane mushroom. The brand has been recognised as one of the pioneers in the emerging mushroom beer segment and is part of a broader movement within the UK craft beer scene towards functional, plant-based, and alcohol-free alternatives.
