I normally shake 4 Aluballs in my Alubottle for 2 minutes, then I pour the drink into a pitcher, then I add water to the top and shake again for two minutes. I do it this way because many of you do two washes in a row. But it occurred to me I could save myself the trouble of doing two washes and just shake the Alubottle for twice as long as I normally do, which would be a total of 4 minutes. Is there any advantage of doing two washes vs one wash but shaking or kneading twice as long? Could it be that the amount of water in my Alubottle reaches a saturation point after a few minutes, and consequently there are no more kavalactones being extracted after a few minutes unless you replace the water?
