When I talked to Sandy it looked like the '15 styles fit fairly well into '08-'15 categories, with the big 3 split up to make 31. So, APA would have own category, American Amber/Brown would have own category, small stouts split from bigger stouts, and AIPA its own cat too. I believe the American Wild were in a big Specialty Category.
I'm certain Historical Styles will be welcome, and will be judged by their existing guidelines where possible but also certain they won't have their own category - they'll either be in specialty, split up to categories they fit better, or more likely IMO, a combination of both.
As before, if the AHA could make this official, that'd be great.
