I'm not trying to get too far off-topic here. The BA is engaging on marketing on behalf of their members (press release). They're saying "this is what craft brewing is" and they're defining it as small, independent, with no adjuncts to "lighten flavor," whatever that means. There's no mention of "quality" anywhere in the press release. So, it's not really about the beer. It's about defining "craft" as the opposite of whatever BMC does, and if BMC manages to make beer that tastes good, don't be fooled, because it's not really good.
Maybe in the 80s and 90s, when "craft" was new, it was fine to define it as "not BMC." That's not a sustainable position going forward. BMC hires some of the most technically proficient brewers and QC people in the world. They are capable of making good beer, and probably better beer than 90% of the current "craft" brewers. I suspect that's why the BA is focusing on factors other than "quality," because they know they couldn't really compete, if BMC honestly tried to crush small brewers in the flavor department.
I don't watch broadcast TV (I use Hulu and Netflix), so I don't really have any idea how ubiquitous BMC advertising is, or what the content is.
