Well, if a couple is e.g. of English descent, they cannot expect to have a baby that looks Chinese simply because their child is born in China.
Likewise, the aroma of wild agarwood oleoresin from one region can never be mimicked by that of another region.
Having said that, the kid can grow up and assimilate, adopting the culture, language, attire, etc. These can be likened to the 'auxiliary notes'.
For this reason, some may smell a Cambodian and say, wow that smells an awful lot like an Indian oud. But it wouldn't be the essence of Indian agarwood, the
oleoresin, their mind is likening it to. Its actually the auxiliary notes that were shaped by the choice of distillation parameters, including-but-not-limited-to the ones you mentioned (condenser, water, apparatus).
Now here's what's interesting-
White (bunk) wood is the mother of all auxiliary notes. For each region/species, the auxiliary notes are what
usually define the scent profile, the 'flavor' of standard grade oud. They ARE what make most Borneos Borneo, Thais Thai, Ceylons Ceylon, and so on. But they are ALSO what can be shaped the most easily by tweaking distillation parameters.
So what does that mean?
1) Using a very neutral set of parameters, bunk wood (standard grade) oud oils of any given region will produce an oil with the most region-specific auxiliary notes.
2) But those very same auxiliary scent compounds are also the most malleable, i.e. precisely these same compounds are what can be shaped to make a Cambodi smell Hindi, a Malay smell Thai, a Ceylon smell Borneo, and so on.
Now is that neat or is that neat?
And here's what I think Ensar's trying to say (if I may be so bold to speak on his behalf), at least this is what I've been trying to say:
For LOT/MOTA oud oils, all these things are irrelevant. Because the aim is to excise and isolate the purest expression of the
oleoresin's scent, untainted by auxiliary notes (and techniques/parameters). No doubt, every distiller will have their own set of in-house techniques & parameters to ensure there is minimal noise captured.
The most amazing thing....? An oil can be distilled terribly wrong, but if it was extracted from oleoresin-packed wood then time alone will allow the oleoresin to rise up and dominate the auxiliary stuff. This is the reason why oils that were distilled 20 or 30 years ago using crude apparatus and techniques but from
awesome high grade wood will dominate a more contemporary oil distilled using superior apparatus and techniques but inferior wood.
The ultimate champion? The best wood
and apparatus
and techniques.
