Hey sorry I couldn't stick around for a couple, but I was actually thinking about something like this on the way home. I'm sure we could probably rope in Paul(s) from Wigram too; didn't they do something similar awhile back?
The problem with BJCP is that to maintain your certification, you need to judge in a minimum number of BJCP recognised contests per year. We don't have any in NZ. This was one of the stumbling blocks faced by Stu when he tried to organise something similar a couple of years back.
I think what we are trying to capture is the understanding of each style, and how that relates to what we brew ourselves.
Although I don't tend to brew rigidly to style, it will become a necessity to be able to identify how my beer measures up against judging guidelines when I intend to enter competitions.
