Whether a kava is tudei is determined by the relative amounts of the different kavalactones in it. Those are the chemicals that give kava its effects. Kavas whose kavalactone profile is dominated by the kavalactones known as "DHM" and "DHK" are known as tudeis, whereas varieties where the kavalactone called "kavain" is more prominent are noble. This chemical profile can be measured, and forum member
@Deleted User here has done so for Koniak, and unequivocally demonstrated that it is tudei. See his results here ===>
True Kava
I'm not trying to start an argument here, I just feel it's important for people new to kava to get accurate information.
Note, in this comment I'm strictly talking about the standard USP kavalactone test Deleted User does, not about any experimental tests.
