Really? I haven't tried it in a while, but I found Grand Soir to be disgustingly sweet and super, super synthetic. That's one of my problems with MFKs: they're all REALLY synthetic smelling to my nose. Like, synthetic isn't necessarily a bad thing, but his fragrances mostly just smell like somewhat-pleasant chemicals to me. I just don't like any of his line and have a really hard time justifying the prices.I enjoy Ysatis as well. Today, I am wearing Grand Soir, and thought I would share my thoughts. It's a rich, heady amber fragrance. There's benzoin in it, and some sweetness from vanilla and tonka. I don't find it too sweet though. It's a powerhouse -- so just one spray for me, otherwise it will be too much. There's a very slight synthetic note in the evolution, but it's not very obvious.
Montale/Mancera are synthetic in a really similar way to my nose.
