Birell is an alcohol-free lager from Nošovice in the Czech Republic. The recipe was developed in collaboration with Swiss brewmasters to achieve the character of a traditional Czech pilsner. Rather than removing alcohol after brewing, it uses a specially developed yeast strain that produces very little alcohol during fermentation, removing the need for a separate alcohol-removal step. It sits alongside Birell Polotmavý, an amber lager in the same AF range.
