Mash Gang Siege Perilous Lager
By Mash Gang · UK
A 0.5% Bohemian-style pale lager, dry-hopped with Saaz. Retailers describe a clear golden beer with sweet, bready malt, a spicy, herbal hop aroma, moderate bitterness and a crisp, dry finish. It’s no longer on sale at the shops we checked.
At 0.5% ABV, this isn’t alcohol-free under UK guidance, which keeps the term for 0.05% or less. We list it with alcohol-free beers, as UK shops do. How UK labels work
What is Siege Perilous?
The Siege Perilous is the empty seat at King Arthur’s Round Table, kept for the knight who would find the Grail. Mash Gang’s retail copy borrows the legend: it calls the beer “a simple bohemian lager”, “elevated to the stuff of legend” by Saaz hops in the dry hop.
Retailers describe a clear, golden lager with a dense white head and moderate carbonation, a spicy, herbal Saaz aroma balanced by sweet, bready malt, a medium body, and a crisp, dry finish with moderate bitterness. Brew Cavern and Raynville both list it as vegan.
Mash Gang no longer sells it on its own shop, Dry Drinker and Wise Bartender don’t list it, and the bottle shops we found it at, Brew Cavern and Raynville, had sold out when we checked in October 2026. For a pale, malt-led lager in stock, try Nirvana Bavarian Helles or Lucky Saint, or see the alcohol-free lager hub.

About Mash Gang
Mash Gang began in 2020, during the first lockdown, as a home-brewing project between friends, and it makes only alcohol-free beer. It has no brewery of its own: its beers are brewed to 0.5% with partner breweries, which have included Northern Monk in Leeds and Fierce Beer in Aberdeen, and from 2026 Hall & Woodhouse in Dorset. The non-alcoholic drinks company DioniLife has owned it since 2024. Its core range today is Chug, Glug and Journey Juice, alongside Lesser Evil, a cherry chocolate stout.
