Permanent series: industry and technology - Germany / Federal Republic of Germany 1982 - 130 Pfennig

Supplementary values ​​to the postage stamp continuous series »Industrie und Technik« introduced in 1975/76. The postage stamps appear at the same time and the same motif as the inscription "Deutsche Bundespost Berlin". The brewhouse is the heart of every brewery. In the characteristic copper pans and vats of the traditional brewery, beer is made from malt, hops, yeast and water. Beer may be produced in the Federal Republic of Germany according to the purity requirement only from these raw materials. The Purity Law, which was issued on April 23, 1516 by Duke William IV, is the oldest food law rule in the world. This has remained virtually unchanged and is now laid down in the Beer Tax Law, which states that "... beer ... only malt, hops, yeast and water may be used ...". When brewing beer, the finished brewing salt is first crushed, mixed with water (mashed) and slowly heated in the mash pan. Next stop is the brewing pan with its characteristic brewing hood. Here, the hops are added and the wort cooked for one to two hours. The last »ingredient« is the brewer's yeast. After fermentation, the beer is pumped into large tanks and matured in the storage cellar at temperatures around zero degrees to perfection. (Text: German Brewers Association eV, Bonn)
