That's a really interesting little document, thanks for the post, kiwi.
And yes, I'd have to agree with Pappers - as much as I love to rag on the big brewers, the use of locally sourced ingredients is, at the very least, kinda neat (sorghum beer!?). I wish I could believe that it wasn't simply about 'bottom-line' economics (which, of course, it is), but I think that a growing global beer consumption has to be a good thing. In reality, it's only the big guys who can afford to get things like that established, so perhaps once they've done a bit more of the dirty work, and converted enough people to beer, then the grassroots (homebrewing, micro brewing) stuff will have a chance to blossom. From the manures of big-industry, the flowers of independent creation!
