I have a beer going to the 2nd round too, and I put down the brewing network as my club. Again, not really a club.
The clubs that win are competitive in nature. It was my expectation that the majority of winners would be from clubs. They have the resources (both in equipment and knowledge) to make better beer.
Why would that be? Why would someone in a store-front club have a better system, equipment, and knowledge than I would (who entered the last competition with HBT as the "home" club- as we ARE an AHA recognized club)? I don't enter competitions anymore, just because of lack of time and inclination, and I'm judging some comps. But I would say the odds of my winning wouldn't have a thing to do with my club.
I have a pretty cool system. I have a bit of knowledge and experience. I've brewed about 300 batches. I make good beer.
Some clubs (like those San Diego crazies!) have a ton of great brewers. That's why they win, though. They have lots of great brewers as members. So does HBT.
But why would someone who wins a competition necessarily be in a "competitive club"? Most clubs of homebrewers are the coolest places to be and with the most uncompetitive people I know. Even as a visitor to a club meeting in Grand Rapids (thanks for having me!), I was welcomed and everybody was sampling. Not a cut throat in the bunch, but some award winning mead and beer makers.
