I've been smapling a small amount of aleswood/agarwood
I've had for a few years
sitting in it's air tight jar with color sensitive glass
anyhow it is a Tsukigase, a nicer quality Agarwood
It has a musky smell almost like sandalwood
then it has a lighter note almost like violet leaves
it lingers both a sweet and pleasantry

I've also used the cheaper forms of this precious ingredient
it truly does not compare though....heh.....some is better than none
anyone tried anything better?
