Email them and ask lol.Why is there one for Europe?
By all means let the USian brewers associations set parameters for their own competitions, but let them also keep their noses out of everybody else's business. I've looked at these so called "guidelines" (read "decrees") and they're pretty naff for many European styles as well as English styles.
I will say one thing though Gordon Strong is a hell of a brewer. I'm not condoning the BJCP debacle.
