This is our fourth Agarwood oil, without going into the details of what it took to get my hands on this batch of wood, the only back-story worth noting is that the wood was intended for the wholesale market to be burned as incense distillation of such a calibre of wood would be too crazy due to the low yield of agarwood but the market demanded and nothing but, so the wood ended up getting powdered for distillation instead (notice the powdered coffee appearance of the ground up wood, the inimitable sign of a true high grade agarwood distillation unlike the beige powders of oil-grade wood which are typically used for distillation). Our Associates have been growing 35 mature trees alongside saplings in the sprawling two-acre land around his home . Materials: 100% Natural Wild Agarwood Heart Grade: Rich Oils Old Worm Hole Resinous Formation Agarwood Smell: Strong, Very Woody, Natural Earthy, Extremely Smokey, Mild Coco About Product : The biggest difference between Perfumes/Colognes and Perfume Oils, is that Oils don t contain any alcohol nor water.
