A Wickedly Hoppy Non-Alcoholic IPA from Scotland's Williams Bros
Joker AF is the alcohol-free version of Williams Bros' celebrated Joker IPA — and it's still wickedly hoppy.

Smooth mouthfeel, serious hop character, zero alcohol. Sure to put a smile on your face — even the day after.

Why Thiolised Yeast Makes Better Alcohol Free Beer
Thiolised yeast solves one of the biggest challenges in alcohol-free brewing: making the beer actually taste vibrant, fruity and complex — not thin, sweet or worty.
Hidden inside malt and hops are odourless chemical compounds called thiols. In normal brewing, standard yeast leaves them locked up and flavourless. Thiolised yeast contains an active enzyme (beta-lyase) that sets these compounds free, releasing intensely aromatic flavours of passion fruit, guava, grapefruit and tropical citrus — even at tiny trace levels.
For alcohol-free beer, this is a game-changer. Because alcohol carries and amplifies flavour, removing it can leave beer tasting flat and cardboard-like. Thiolised yeast compensates by delivering a massive punch of natural fruitiness that makes AF beer taste genuinely hoppy, aromatic and full of character. Williams Bros use it in all their alcohol-free beers — and it shows.
