I am in the process of preparing to teach a German beer style class for American Brewmaster as part of their advanced homebrewing classes. I'll be including Austrian and even Czech styles in the class, but that will probably be the outer limit. I feel pretty comfortable with them or I wouldn't be doing the class. That said I haven't been to Germany recently so I am curious if there is anything new that I may want to mention. I did pickup Good Beer Guide: Prague and the Czech Republic by Evan Rail for the Czech beers. I'll be covering beer styles, beer bar culture(including Oktoberfest), and homebrew recipes. If you have any suggestions please leave a comment or email me geistbear(at)gmail(dot)com.
