This oil is one of my favorites so far! Unfortunately, there is some variation between batches - the imp that I initially bought has a very strong fir scent, whereas the bottle and second imp that I bought afterwards have almost no fir. In all of them, I can smell the hyacinth and jasmine, with the jasmine sort of forming a background for the hyacinth. But without the strong fir smell, the hyacinth becomes a bit overpowering, and it smells oddly like bubblegum if I concentrate on picking out individual notes. That's not a terrible thing, because it's a cute, spring-like scent; it's just that the fir made it more unique and sophisticated.
I'm thinking that I might try and layer this with another oil that has fir or pine as a dominant note. For now, though, I'm hoarding that first imp for special occasions.
