Thai oud oil can be very interesting. There is a certain common aroma to all my Thai oils that I'm a little tired of, but there are also some amazing aromas that distinguish them. I have one that has a really nice, classic, sweet lingering classic agarwood base-note that keeps surprising me. A couple of others that, after the initial blast dies down, almost resemble the smoke I have smelled coming from gently heated quality Vietnamese wood. Another brings Cambodian oud to mind and yet another smells like it is from Borneo. All this variety is something that surprised me. The Thai oils I have are all a mixed bag though - each has something excellent to them and something a bit odd. They are a bit harder for me to enjoy straight-up... this region appeals less to me than many others but at the same time they are an essential part of my collection and I find myself applying them daily and ignoring the rough parts in order to get access to the more fleeting sublime notes. I have only a few Thai oils: Feel oud bio ko chan 1, 2, 3 Feel oud Thai, name was something like bio chan (?) not sure Sweet Trat Some kind souls here sent me several vials with Thai oil samples, but I don't have names / makes on these. All in all I think I have sniffed about 10 oils of Thai origin. I don't have any wood from Thailand either.
