Yes, I was there last year and visited the Onomea Tea Company. http://onotea.com/index.php?option=com_ ... e&Itemid=1
There is quite a frenzy to obtain this tea by the islanders. The owner had apologized profusely over the lack of tea quantity and also that fact that some of, actually most of, what he felt were his best teas, were sold out. The locals are dialed in and anxiously await the harvest, and snap them up as soon as they roll out, leaving little for sale. Even some is purchased by a special Taiwan agent who buys for high demand Taiwanese clientele with a taste for Hawaiian tea. No wonder it is so hard to procure! Premium demand creates premium pricing and unfortunately.
Is it worth it? It is if you are looking for the experience of drinking a Hawaiian grown tea, of course absolutely. Will it replace your morning black? Probably not unless you live in Hawaii ... on Kona.
