Kava instructions usually recommend 5-10 minutes of kneading, but the Aluball and Alubottle instructions only recommend a minute of shaking. Is this because there is only so many kavalactones which can be extracted by the Aluballs which tops out at a minute, or is it that the extraction process is 5-10 times more efficient? If it is 5-10 times more efficient, will shaking the Aluballs in the same water for 5-10 minutes extract many more kavalactones than kneading would? I realize that there are diminishing returns for either process, and there are only a certain amount of kavalactones which will leave the powder and enter the liquid until the water becomes saturated and can hold no more.
