Thanks gents - great show!
Some comments:
- Franziskaner is definitely a Hefeweizenbier. 
- Did you chill them? They should be drunk from the fridge (or if draft they are served chilled). Great for a summer evening in the Biergarten!
In my opinion, all german weizenbiers of this type are hefeweizen. Based on my experience in Germany (my wife is German and comes from the south), if you ask for a Weizenbier, you will get a helleshefeweizen beer. Often you will get beer from a local brewery, and not from the big brewers. That beer doesn't make it to the UK (sadly).
There are actually three types of hefeweizen:
- Dunkel (dark)
- Helles (light - what you have both drunk)
- Krystall - this is Helleshefeweizen with the yeast and wheat proteins filtered out. Often drunk with a slice of lemon in the top.
I agree with your comment about not mixing it- I have had many great evenings treating these as a session beer!

Looking forward to the next episode!
