You all are talking about "oud" as if it were a McDonald's Hamburger. A hamburger from McDonalds tastes the same no matter where or when you buy it. One from Moscow tastes the same as one from Detroit. Oud is NOT like that. Different trees, different growing seasons, different countries and the Oud smells drastically different. Agarwood, also known as oud, oodh or agar, is a dark resinous heartwood that forms in Aquilaria and Gyrinops trees. When the tree is infected by a mold, it's immune response produces this thick rich smelling oil. Like different wines grown in different locations, oud depends on where and when it was grown. It comes from Thailand, Vietnam, Cambodia, the Phillip pines, Papua New Guinea, Indonesia, Malaysia, China, and India. I believe MOST oud is produced in plantations of trees planted by suppliers. I own a bottle of mid-grade oud, about 3mls that I daub occasionally in unscented lotion, then wear. It wasn't too expensive when you consider that like Amouage Tribute, one daub will last all day. BTW, whoever mentioned Mona d'Orio is correct, before she died, she tried many ouds, disliking them, until she found a very expensive variety from Laos which she loved. She used it in her Oud fragrances. You can find a very nice interview with her on YouTube where she discusses this.
