Luigi, if I may butt it..
I recently got my distiller to do a special distillation for me, using actual incense grade wood (believe me, a lot of people claim that, but the term 'incense grade' is way too general). Those over here who I showed an actual chip from the batch of wood used (as well as a 'typical' chip usually used), could maybe comment on that.
I asked the guy not to soak the wood at all. And to use atmospheric pressure (0 psig) to extract the oil, using a steam distillation unit.
Given these factors, the oil really had to be literally cajoled out of the wood. It took about 3 weeks, with a not-so-high temperature (so the oil didn't get a burned smell), for the process. Compare that to, for example, 1-3 days for RK's DS oils. Or 3-7 days for many others. 3-10 I'd say is about the average.
One more thing - the Crassna species somehow naturally yields a higher percentage of oil. And it's thicker too (is there a correlation?), compared to the oil of other species.
Taha if you dont mind, please tell us what is the oil that you got is like?
I decided to share that bit of info because I thought it'd be a nice contribution to the thread, since we all share whatever information we can.
I'm afraid if I say any further, I could get in trouble (someone previously thought I was advertising, and my wrist was slapped as a result). So check your inbox. : )
Wog: my notes on Taha's custom Malinau distillation:
On application- cool, gauzy (what some might call menthol) top note, subtle smokiness, faint mustiness, lovely warm, pipe tobacco sweetness, mineral-y salt, parched earth, dry and herbal. Surprise of citrus rind! Quite soon it morphs into subtle herbs and woods accompanied by vanilla, powder, accents of creamsicles and smoldering ashes. There's also a sprinkling of cocoa in this vanillic stage. The drydown is soft, herbal, mineral-y, woods. Unusually complex and meandering. A Malinau-smeared thumbs up!
Thank you Taha and Bluemoon.
how is the best way to conserv the oils? in the dark? glass bottles? a lot of bottles have the plastic dab - the plastic influence the oils?
Glass sticks are much better. The plastic stick could influence the oil.
I find oud is like the total opposite of perfume. The warmer the temp the more light that goes through the bottle and the longer you don't use it.... The better it ages.
I have an agaraura Thai oud that was available a couple months ago. When I first bought it I didn't really like it. But now after sitting there a few months it's all smoothed out and is very nice! Now I look forward to wearing it!
Sometimes to advance aging I put a half ml in a sample vial. Move it all around once or twice a day. Try to leave it in the sun in my window..... It hurrys the aging process.
usually if you put an oil in sun (with aer) it become thicker and "concentrated", more trasparent/traslucid and less dark - it's a double process - it loose all the water that he has and the molecule become bigger (polymerize and oxidize). for this the ancient painters leaved their oils in hot sun (best method) or boile them (worst method but the most rapid one)
