Beer 40 is a German Hefeweizen: The Original.  I have a great fondness for this Brewery (Schneider-Weisse) having visited both the Brewery in Kelheim and the Weisse Brauhaus in Munich (site of the original Brewery).

I’m a big fan! Why is it called Tap 7? If you go to the Weisses Brauhaus, it is Tap #7.  Go give it a try!  Beer Mentor
