I personally keep my Oud purchases between Ensar Oud and Agar Aura, end of story.
You are missing out on a lot of nice oud oils Oudiferous, but I bet you get a lot of free samples. Your reviews are poetic
I've tried Sharif's Kashmiri Musk. It's a nice musk, but again, I wouldn't be able to tell if it is pure deer musk or not (most likely not).
Which Kashmiri Kasthuri did you try ? Last time I checked there were at least 3. When people start throwing around the 'P' word in connection with musk, it makes
me feel like having some fun. Really, the only thing that is 'pure' musk is the contents of the musk gland of the musk deer. You wouldn't want to rub some on your wrist
All musks are diluted for use, either in oil or alcohol. Its very hard to fool someone with a synthetic musk base into thinking it is real musk. I've never seen anyone try to do it.
Even within the category of so called 'pure' musk attars or tinctures, there is a great deal of variance in scent. Each one is different - the differences depend on the diet of the deer, its locale, age, time that the musk pod was taken or found, sub-species and many other things. These distinctions are far more important to people who know about musk than this elusive term 'pure'. If you want to try a nice musk attar, try Sharif's Musk Sharif. It smells like a nice Kashmiri Kasthuri with a little rose to balance the animalic side of the musk.
Now lets look at the 'P' word in the context of oud oils. I've very rarely run into an adulterated oud oil. I've run into a few which might have been cut a little with sandalwood but I've never run into one that has any synthetic oud chemicals added. Like musk, the perceived quality of oud depends very much on many factors other than so called purity. When I decide to purchase an oud, it is because I like the smell of it, its sillage, its lasting power, the way it modifies my state of mind, and many other factors. I don't look at an oil and say this one is pure so I like it and this one isn't pure so I can't like it. Purity has little to do with it.
Most vendors who wave around the 'P' word and insinuate that other vendor's products may not be 'pure' are trying to sell a concept, not a product. The product may or may not be nice, but when I hear the 'P' word, I hear a marketing campaign.
In some cases, like Ensar, the purity of his product is a side effect of his artisanal approach to producing oils, but its the meticulous and discerning care he apparently takes with his products, not their purity, which distinguishes them. I don't know about Agar Aura but I have no reason to doubt that they have nice oils too.
