It must be every drinker’s dream and it has now become a reality, at least if you believe the manufacturer. Keep young and beautiful by drinking beer - that is what Bavarian entrepreneur Helmut Fricher is promising. Anti-ageing beer was presented to the world at a German agricultural fair this week - a drink which the brewer says will bring body and soul into harmony. But the new wonder drink may fall foul of Germany’s oldest law, the Beer Purity Regulation. The anti-ageing beer that Mr Fricher presented to the Green Week trade fair in Berlin is supposed to help strengthen the immune system and make you feel good in a way that other beers just do not.
