Central City Brewers + Distillers makes Street Legal Nitro Stout in British Columbia, an award-winning alcohol-free beer that ranks as one of Canada's first non-alcoholic craft beers and the bestselling dealcoholised beer in the province's liquor stores. It is brewed traditionally at full strength, then run through a cross-flow filtration system that uses a fine membrane to separate out the alcohol: the beer is reduced to around 1% ABV before deaerated water is added to bring it just below 0.5%. The result tastes of dark chocolate.
