Hmmm, similar color to the Koniak (which is not tudei apparently). Anyways, I e-mailed Dr Lebot stating my procedure and attached the 1st photo (with all 3 samples) and asked: 1. Is the color of the Koniak consistent with tudei kava and 2. What is the reason for the particulate that hasn't settled yet. Here's his response (there's also really cool information regarding Solomon's Island):
"Centrifugation will improve the colors, but your acetonic extract of Borogoru is of the right light yellow color, typical of this variety and this is how it is here. Also, the so called "koniak" variety cultivated around Madang, is in fact called "isa" in local vernacular language and is indeed a two-days kava, with a typical ambre color just like your acetonic extract. Also, the only P. methysticum cultivated in the Solomons, is as far as I know, Borogu (syn Borogoru) originating from Pentecost Island, Vanuatu.
We use centrifugation and we compare colors of the supernatant.
