i like using powdered kava and drinking it all, sediment and all. I believe you are correct on some of the actives being fat soluble as opposed to water soluble, I also think some are heat sensitive. I think this one is supposed to be consumed whole... although a knowledgeable friend talks about making kava drinks out of quarter pounds of the stuff and filtering, for a very very potent drink. It just doesn't seem cost effective or to grab the entirety of the actives in my opinion though. I vote for yellow piss and + dizziness, almond milk and powder all the way! I love how enough kava causes me to hallucinate and causes my depth perception to fuck with the words on a computer screen. Some of them even dance!
