I was out of the country for the past 3 weeks so this is all news to me yesterday and today. What I've read has never made any claims of quality concerning what's in the bottle. All it seemed to indicate was, if you care about local/craft beer and you don't like the way the macros do business, this little up-side-down bottle lets you know the beer you are looking at is not owned by a conglomerate you may not wish to support. Period.
This is all well and good for those of us who are deep into the industry, but as always these moves are made for the "rest of the world" who don't care as much where the stuff in the can comes from.
As with most things that go on a label, as several people have mentioned above, there will be an implied quality statement with the logo. That's just how food labels work. I'm a food scientist and there's a lot of stuff that goes on food labels and of course if it goes on a label it must be important right? That's how people's brains work. The FDA doesn't regulate beer labels yet, but it's coming very soon. We're already having to work on calories and nutrition facts labels.
There's a lot of stuff out there that have nothing to do with quality, but crafty advertisers or just human intellect of "this must be different and special" turns into quality statements. For example, if I say the words Black Angus, what do you think? Most people are going to think about a fancy downtown steakhouse like Ruth's Chris. Black Angus is a breed of cattle. Not a quality designation. There are three grades of meat, Select, Choice and Prime. Choice is what you get in the grocery store, Prime is what you get in Ruth's Chris, but they are both still Black Angus. When Hardees/Carl's Jr is advertising Angus Burgers they are banking on most people equating that with expensive steak. Are they using Prime beef? Hell no, they are using Choice (or even Select) but people equate Angus with Prime.
The BA's selling point is "local and independent is better".. better how? Better for the economy, better business practices, better for your community etc etc. Over time most people will turn that into "better quality" or "tastes better". Is the BA trying to intentionally mislead people? No, I don't think so, but they are certainly taking advantage of how human emotions work to push their message. In essence that's how all advertising works. Is it meant as a quality statement? No, but in 5 years that's not what people will remember about it. People automatically assume "better quality" and pay a premium for things like "Natural", "No Corn Syrup", "Free Range", "Dolphin Safe" "GMO Free" etc etc, all of which are unregulated and mostly meaningless statements (Organic is the only one certified by the government) and don't always (or sometimes ever) equate to product quality. It's a shell game.. and it always has been.
