Just thought I'd add my general view of the fresh kava consumption in Vanuatu. I'll put it here and under my picture threads as well.
In general, I'll say kava is kava. Drinking fresh ni-van kava is unquestionably better, in every way, but it's still just kava and not a drastically different experience.
The best way I can describe it, is that every negative attribute is lessened, while all the positives are more easily attained. The taste is less bitter and easier to drink, but it does still taste like kava. There is some difficult to describe 'sparkle' to the flavor that seems unique to the fresh experience. A few months ago I had some fresh frozen Hawaiian kava, it had a distinct cucumber/vegetable juice flavor that I didn't taste so much in the fresh Vanuatu stuff. A lot of the stuff I tasted in Vanuatu had similar flavors to each other, but differed in the strength or 'depth of flavor'. There was one odd and heavy kava I had that had a strange soured finish, I think it may have been old kava, but I'm not sure.
The buzz was very easy to attain, as opposed to the trouble I have 'getting there' at home, with my dry powders. Although nausea was certainly still possible after enough shells, it was overall less nauseating, less bloating and less heavy feeling on the guts. Those things are huge obstacles for me and my personal body chemistry, when drinking dry powder, it often is bad enough to hinder me from enjoying or feeling the experience completely. It was 80-90% improved when drinking fresh kava. I'm guessing this must be due to having a higher kavalactone content while simultaneously having less root particles/sediment in the beverage. Which isn't how things work when I brew up dry stuff.
The whole feeling was generally lighter, easier and more blissful than the majority of my dry experiences.
It appears the best time to get kava at the nakamal would be between 4pm-7pm...many places can sell out, but it seems there's always another place to go if it does.
The hacking, hawking and spitting is in full force...it's actually is fairly effective at getting some of the taste out of your mouth. Next time you have a shell, go spit in a white sink afterwards and you'll see persistent brown kava-laced saliva is in your mouth forcing you to keep tasting the flavor. Beyond that, there seems to be something in fresh kava
more so than dry, that creates the need for hacking and hawking. I never felt this with dry, but many of the fresh kavas would create a phlegm/mucous build up in your throat that demands to be hawked. My bus driver/nakamal buddy told me this is normal. "In Vanuatu before kava, nobody cough. After kava, everyone coughing coughing."
Most shells are either 100 vatu or 150 vatu, which is about .90 cents to $1.33 USD. You aren't limited to these sizes though, as you can can basically hand the vendor anything and tell them how many Vatu you want to pay...and they will fill accordingly. I'd say the 100v shell would be about 6 gulps while the 150v shell is closer to 8 or 9. I found that anytime a local walked me to a nakamal they wanted to buy me a shell, I always made sure to reciprocate even though I don't think it was expected at all. They also all seemed concerned if I didn't have something to eat afterwards and would encourage me to take something of theirs to eat.
Mornings always felt fresh, even the couple times I drank suspiciously heavy kava. As far as Tudei conversations with locals (who of course don't know the science),
I was simply told things like "No, no don't drink the Tudei plant, that is no good". "Oh the yellow kava, that is no good for drink". "Tudei kava make you feel bad and no good in the morning, other kava make you feel fresh and when you wake up you feel more smart". Their point of view seems to be based simply on hating the effects of Tudeis.
If I had the option, I would drink fresh kava exclusively. Having seen and done a few of the external adventures in Vanuatu now, I can see why @nemo is okay with traveling there simply to hang around Vila drinking kava and not much else. If i were in closer proximity, I would certainly bip over on whims now and do the same thing.
