In a recent Chow article online, Lessley Anderson gives a fairly decent account of Brettanomyces beers. I would have preferred a different title than Your Beer Smells Like Goat, but I guess it does grab your attention. Apart from too many references to stinky aromas, it’s a good overview and includes a nice list of examples. Still, if you’re not too familiar with beers made with wild yeast, it’s a good introduction; worth a read.
