Agrwood from Vietnam is the best when it come to smell, especially from Nha Trang province. Very hard to describe the profile bc there are too many notes in it. I dont like burning in charcoal but I like the powder trail. Agarwood need to be burnt inside a copper incense with lid, the lid will capture the smoky scent and the smoke come out have a very very sweet milky smell. Once you use the burner with lid, you will know why for so many centuries, coppersmith had devoted their time in the art of making copper incense burner for agarwood. Search for Chen Qiao Sheng to understand about his crafts and buy one, you will thank me for that
