Thanks for all the input, everyone.
@Deleted User01 You can remove makas during the pounding by using different sized screens and a vibrating sifter. It would be a bit of a learning process for me because we've never done it before. The 11 Year micro is processed by the supplier.
@Myk You definitely need a good amount of powder for the right effect. 5 grams of a 10% kavalactone kava would get you 500 milligrams of kavalactones, which is enough for a strong effect. It's also a good size spoon full of kava though. Of course if you're using a milder root, say 6%, you would need quite a bit more, 80%, for the same effect.
Unfortunately, I won't be able to get Nambawan micro. Part of what makes that kava so amazing is the processing technique, which the supplier is very secretive about. He would possibly sell me the roots, but according to him, there's more to it than that.
@Zentri I absolutely do not recommend micros for people with finicky stomachs or people that are prone to dermo. That's part of the reason we don't offer more micro options already. We are a lot of people's introduction to kava. Newbies would probably be enticed by the ease of micro, but some would undoubtedly get upset stomachs and think that all kava does that. Removing the makas definitely helps but not for everybody.
@Tfin You definitely sound like a micro fan. Keep a close eye on bulakavahouse.com. If we decide to go forward the earliest they will be available is a month or two.
