That website doen't satisfy my curiosity. Much of it is just a copy
from the other page. In this case, the older leaves of Tieguanyin are
used. They're fermented and then immediately freeze dried. (It doesn't
say this, but I supposed it's made into soluble tea crystals.) But
what I don't understand is, why go to all the trouble of
nanotechnology to enrich the tea? Why not just fortify the tea with a
blend of vitamins and minerals - like they do with cereal and other
food products?

And if it is manufactured at a nanoparticle size, how safe is that to
have in your home? When you put the tea into the cup, how much of
those nanoparticles are going to fly up into your nose and mouth and
into the lungs? What if you sneeze just at that moment? And when you
drink the tea, and smell it, are nanoparticles going into the lungs?
And what if those nanoparticles cause mesothelioma? Scary stuff.

I don't like the technolatry of tea. Tea should be a natural product.
Let's keep it that way and not mess up a good thing.
