Windhoek Lager, in contrast to most of its competitors, is brewed according to an old German tradition known as the Rheinheitsgebot. This ensures that it contains only natural ingredients: it is 100% real beer. This radio ad was part of a broader campaign that reminded consumers to 'Keep it real', with Windhoek lager, a statement which reflects both the intrinsic qualities of the beer and the brand’s attitude and character.
