I think novices who dislike the taste (like the original poster) might benefit from being directed to a different type of Kava. Something mild like Nak@Home's White Sand, or even something like BKH's Boroguru which is fairly strong but still has a tolerable taste.
And of course if they're willing to venture outside of soak-and-knead kava, there's always Ozia candies, Paradise extracts, and all the instants out there...
