When you go to Wikipedia and type in "yuzu", you get this picture. Not so pretty. In fact, a bit homely and rotten looking. We carry our products in yuzu scent and customers ask me all the time what it is. This is hard to explain, because it's a tangy version of a lemon/grapefruit/tangerine mixture. I guess you will have to smell it for yourself. Other than lemon (which smells like a freshly cut lemon---NOT kitchen cleaner!), yuzu is my favorite scent. Keep in mind that I prefer citrus over floral notes and I love the tropics more than Antarctica.
Don't always judge a book by its cover. You may pass some lovely Ugly Ducklings.
