Absolutely. Tasting as defined by the IOOC is about detecting
faults/assuring quality: but the same technique will allow a producer (or
critic) to understand all the flavour components at work in the oil, and
that may affect work in the grove as well as marketing blurb. On the subject
of oil ageing: the taster is shooting at a moving target. The taste of an
oil changes with time from harvest. As an interesting aside, a local Barnea
producer tells me that the oil, bland immediately after pressing, develops
more flavour after a month or two.

Thanks for that. I look forward to reading it.
