If anyone wonders what the Yuzu aroma is like, it's like a mix of mandarin orange, satsuma mandarin, sour marmalade orange (C. aurantium), and lemon all combined together. There's a lesser note (maybe 25%) of grapefruit in there, and a very slight but discernable note of guava. There's also something very pungently deep and "spicy" about the fragrance of Yuzu, which is probably one of the first things you'll notice when you smell it. It's a very unique citrus smell.
