In 1988, the Reinheitsgebote became invalid, when the European Union declared it a violation of the competition regulations and an impediment of free trade. Until today, only a few German breweries exist, which make use of other ingredients, such as sugar or the replacement of grains. In Germany, foreign beers are allowed to be sold in. However, almost all of the German beers correspond to the Reinheitsgebot. Mixtures and blends are known as Beer Mix.
