I'm surprised to learn that flavor /aroma wheels are a fairly recent invention. What is a flavor wheel? A way of finding your way to the precise words for what you smell and taste. As far as I can ascertain, it was a professor at UC Davis, Ann Noble, who came up with the first aroma wheel, for wine. Watch her brief video introduction to the wine aroma wheel here. As a writer, I am enchanted at the idea of a tool to help us better describe wine-- or, for that matter, anything.
