They handed out that flavor "map" at one of the tastings. I guess if you've already experienced some of the extremes it can be useful, but as far as distilleries go, it's by no means comprehensive.

As for the wheel, they have similar things around here for the wine. I can't pretend to be able to taste even a third of the flavors listed, so it's pretty much academic to me.

As someone said, "I don't know much about (something), but I know what I like."
