There's a woody/vetiver and amber "backbone" to this fragrance, along with the moderately sharp citrus (the orange is obvious), pepper, and herbs. I don't get much in the way of any other spice note here. Also, it's a bit musky, but not a heavy musk. Mostly, the overall impression I get is a basket of leaves from citrus trees. It's reasonably natural smelling, with decent projection/"sillage" and longevity. If you want something more floral and animalic, go for M. de Morabito. If you want more diversity and dynamism, go for Coriolan (which has a clearer spice not in the base as well as a dry leathery quality). Not sure where the "root beer" impression comes from, because I don't get that at all. This is rather linear, so if you don't like the idea you will not like this fragrance. There is no "waiting for it to get better" with this one. Over time, it seems to just get more mellow. There's nothing "wrong" with it, but if you have a similar fragrance (Greenergy is another one), then you might not be happy if you blind buy it and find that it's not really going to improve your rotation much.
