I'm not a super experienced Kava user, but I'm working hard to become one.
After all the time and effort I've spent on trying to figure out the best way to prepare Kava, I have yet to find the ultimate way, but I now have some basic concepts I use as my guideline.
I view preparing Kava as a battle between me and the Kava root. The fight is to make the root give up to me as many of the Kavalactone oils as possible that it's keeping from me. The more I get the root to give up it's oils, the closer I get to winning the battle.
The two ways I know of to get the root to give up it's oils is agitation and heat.
Examples of agitation are kneading, pounding, chewing, blending, etc. Examples of heat are various ways of using water at temperatures from room temp. to boiling.
You'll find on this forum many different techniques for doing these two basic things and everyone has there favorite. My favorite is the one where I win the battle and get krunked!!
Right now I'm trying with fairly good success a combination of agitation and heat.
I mix hard boiling water with my Kava into a blender and use the blender to agitate the Kava for about a minute or so.
Then I let the mix sit for awhile to let it cool off enough for me to touch without burning my fingers
I then transfer this to a nylon bag and further agitate by kneading the bag until all the liquid is squeezed out of it. This has the added benefit of filtering the root solids from the oils, so I don't have to consume and digest them. After all, I want the oil not the stingy evil root.
I may take the liquid and put it in the nylon bag (or a Fijan bag which is a finer filter) again for further agitation and root filtering. But in either case, I don't like warm Kava so I put mine in the fridge overnight before I drink it.
You know how some foods taste better the next day than right after you cook them? I think leaving the Kava set in the fridge really helps in getting the oils to combine with the water. It makes it taste better and I think makes the oils more digestible (and potent).
Whatever you end up doing I hope you will share your experience and hope you win many battles!!
