Gave the world the VW Golf Gti and the beer purity laws.
sadly another bad myth. A cynical marketing stunt which i'm amazed hasn't been outlawed by the normally regulation-crazed Germany.
Check the back of beer labels for ingredients: 90% of the famous brands have "Hopfenextrakt" (modern chemical-extraction of hops) instead of real hops as their main flavour ingredient.
Not very pure then...they didn't have this kind of tech back in the 1500's lol
Since i realised this about a decade ago i've made a point of only buying beers with actual hops.
German beers which do actually use real hops:
Störtebeker (the best, massive choice too...the heavy 5% Schwarzbier and crisp Atlantik Ale are highlights).
Altenburger...full foamy head but still good fizz.
Becks...surprisingly for such a mainstream brand, but not a great beer to be honest.
Lübzer...decent but loses head quickly.
Alster....posh alkie beer.
Berliner Bärenbräu....was a bit rare but now available in supermarkets. Was pretty good but since that move something not-good happened to the taste.
Holsten...refreshing and light, excellent summer tipple.
Some 'extracted hops' beers actually taste better than the genuinely pure beers (Herforder Pils, Bitburger & Flensburger are particularly good) but if you want a beer closest to the original purity laws then make sure the label's ingredients doesn't have the word "Extrakt" anywhere in it.
Further (depressing) reading...you may need Translate activated. In short, all beers have plastics and chemicals added to them to artificially increase their life-span, keep their colour, head and fizz, prevent bits forming etc:

Conclusion: the famous German Beer Purity Law is a bad bad myth.
