Beer has been brewed in Østerdalen since ancient times. Rena Bryggeri was founded in 1999, and has since continued the excellent beer brewing traditions in Østerdalen. Rena brews 0.33 L bottles in a range of colors, a collection of green, black, and blue. Today, Rena makes three different kinds of beer, a lager, a wheat beer, and a bayer. Twice a year, Rena will invite world leading brewers to create a master collection, the Rosenlund label. The master collection will be made as 0.5 L bottles with a porcelain cork, upon request. These bottles has a special weight and thickness to ensure the products rare quality.
