What color is agarwood ash?

Generally speaking, the incense ash color of good grade agarwood is black, but it is not incense ash black, that is, it must be high grade agarwood. Because fragrant gray and black means more oil, the relative grade will be higher. However, there will be problems in judgment because some perfumers don't like that the incense ashes are black in the furnace, like caterpillars one by one, so some perfumers will add a little charcoal during the brewing process, which will make the incense ashes white. Of course, since the incense ash is of high grade, it is natural to add other things to make the incense ash black. Therefore, it is not certain that the quality of agarwood must be good, but it is not good if the fragrance is gray-black. I'm usually here? Is it sweet? Where to? Zunmai, are they really heavy? That's great.
