The wine tasting wheel from UC Davis has some strange descriptors that are a little off-putting to wine novices. For us, we classify those as "Funky" wines, aromas and flavors that don't necessarily appeal on paper, but can be really interesting:
-Petrol (a favorite in Riesling)
-Dirty gym socks
These flavors can be dominating on the palette, and tough to pair with food. But if properly balanced with some other flavors, these wines can make an interesting drink on their own. They are seldom "easy-drinking" wines, so they are great for linger over those long evenings of conversation.
