It's OK, taste wise, after it's first made, but overnight in the fridge is enough to make it taste like grass-clippings, IMHO.
What's fascinating is the marketing. "This is the BEST!" Whereas about 3Kyo the cultivators of kava (kavavators?) said, "This isn't too bad, but I know we can improve this," and spent several generations turning Madang Short into the sterile cultivars enjoyed today which are much lower in DHK and higher in Kavain.
As a Teetotaler, I enjoy Chief's as "Waeld Koniak." Given the right set, setting, and dose, it does simulate ethanol very well.
Don't tell anyone, but much of the kava vs. ethanol is cultural expectations regarding what the two are "supposed" to do. If you've ever seen a commercial for Corona beer, you'll notice it's marketed as if it were kava - sunset and palm trees included. I should be pretty clear that what I mean is the optical effects... everything becomes "crisp" and somehow brighter and more beautiful, as well as the muscle-relaxant/sedative effects.
I'll stop now, before I forget why I gave up drinking.
