"I detect the aroma of cat's pee in this wine."

"Come again?"
"You know, pipi du chat."

Um, ok. Whatever you call it - cat's pee or the more sophisticated-sounding French version, pipi du chat - there's no getting around the fact that this is one unsettling way to describe something that you're about to drink. Yet, it's a descriptor often used to describe Sauvingnon Blanc. Oddly enough, it's a positive characteristic for a SB to have.
