Ein gutes Bier braucht sieben Minuten. A good beer needs seven minutes. The saying is about beer poured from the tap. The German Brewers’ Association lists the saying among die zehn bekanntesten Irrtümer über Bier, the ten best-known errors about beer. In April 2015 it wrote: Richtig ist: Ein frisches Bier kann und sollte in maximal zwei bis drei Minuten gezapft werden. What is right is that a fresh beer can and should be poured in two to three minutes at most. Michael Eder of the Doemens brewing school in Munich explains that the 7-Minuten-Regel, the seven-minute rule, comes from the time of old beer taps, when a Pils also held much more carbon dioxide than today. The same year, a sales director of the Bitburger brewing group said that the rule had not been valid for a long time.
