The beer is named after the Slavic god Radegast. This, the most popular brand of beer in Moravia and characterised by its bitterness, is brewed in the Nošovice brewery from the highest quality brewing ingredients from Moravia. It was first brewed in 1970. The brand has a strong and loyal following in Moravia and Silesia, but is also popular with beer lovers all over the Czech Republic.

Since 1999 the brewery is owned by Pilsner Urquell, which is, in turn, owned by Asahi Breweries.
