By Karen Peattie A BREWER established in Glasgow three years ago has secured a Scotland-wide listing in Aldi for its low-calorie Gen!us Craft Lager. Genius Brewing’s award-winning lager will feature in the supermarket group’s Scottish Beer Festival which launches in 96 stores across Scotland on Thursday. This is the brewer’s first Scotland-wide listing with a major national retailer. Founded by Jason Clarke and Charlie Craig, Genius Brewing “is on a mission to make healthier drinking a pleasure, not a compromise”. Its Gen!us product, described as a “refreshing light craft lager with a smooth, citrus finish”, contains 79 calories in each 330ml can – fewer than the average apple – and at 3% abv is exactly one unit of alcohol.
