For the most part, I think it's successful. It uses clear verbiage instead of chemical names, although I am curious to know how many non-trained drinkers are going to think "aha! gooseberry!" when quaffing a beer hopped with, for example, Nelson Sauvin hops. I also appreciate that he's trying to educate non-brewers on which components of a beer will produce a particular flavor or aroma. Brewers know that you'll get different flavors from different yeast strains (even if the recipe is otherwise identical), for example. But having all of those flavors and aromas spread out all along the wheel can make reading the chart frustrating and, paradoxically, vague. It also puts "creamed corn" squarely in the faults section, even though certain beer styles need a verrrrrrrry slight bit of that to be true-to-style. These are, of course, the grumblings of the terminally uptight -- the kind of person who got a poster infographic of all of the beer styles in the world as a gift and immediately started grousing about the placement of certain styles on that graphic.
