That's pretty cool, I'll see if I can help you out.
1. Relating beer, the most interesting law is probably the famous German Reinheitsgebot (
http://en.wikipedia.org/wiki/Reinheitsgebot) which limits the ingredients to the classical basics of making beer and it's pretty old. Beer has a huge tradition in Germany, and there are tons of beer types and brands. Usually every region has its own beer, usually "Pils". As I am from Cologne I'll just tell you that our infamous "Kölsch" is the best beer, but everyone outside the radius of 100km around Cologne will disagree though
We love it though and it's usual that you drink Kölsch here. They also sell it only in that ~100km radius around Cologne, in some cool pubs you get it from further away too though. Note that Kölsch is a real type of beer and it's being sold by a good bunch of different brands. All from Cologne.
Basically everyone has his own favourite beer. Often the regional beer type, but there is also a good bunch of beer of bigger breweries that sell it all over the country. Note that the beer in the North of germany is tarter for example or that the "Weißbier" or "Weizen" (wheat beer) from Bavaria differs from Pils type of beer. I recommend to come to Germany and test everything for yourself, there are big differences in beer and it's worth it
2. Religion in the educational system depends a lot on where you live. What I can tell you is that I had religion more or less permanently for 10 years at school and was able to choose philosphy instead after 10th grade. School ended after 13 years for me. (They change it for 12 years next year) They always tried to split the religion lessons into Protestants and Catholics, but because of the lack of teachers to do that we had ecunemical lessons quite often. People with other religions, were usually in the Protestants lesson, as it had and still has the reputation of being more tolerant.
Bavaria for example is a very Catholic region and on a lot of schools there religion lessons have a lot more importance than where I live. I am Protestant and we usually discussed the religious themes ina philosophical or social way. And we usually tried to do themes that make people with other religions take part properly as well, but that was teacher dependend.
