is a green oolong half a green tea?

An oolong is wilt in the sun but “fermented” in the shade. Proper fermentation of oolong requires rolling of the leaves. Something left to wither in the sun is a sun-dried tea, like mao cha for pu-erh. Even when an oolong looks green, it is still an oolong tea. Examples are green style tie guan yin, hairy crab, or “high mountain” oolongs from Taiwan. Someone who said that thing in the blog you read does not know about oolong at all. This is common place in tea blogs or forums in USA.

That is so true. There simply is too much noise out there. I think one reason for this is that some people want to muddle the distinction between things so they can sell their less than genuine products with a good name. This is projecting a wrong image of a category and can kill it. They have hurt white tea so badly, and it seems people are eyeing oolongs now. The only way to counter these “category” killers is to promote genuine quality to as many as possible. On one side we are against mega beverage player like who you know, and on the other, small shops who are trying to sell anything they got hold of to sell at whatever margin they could in whatever name they want. There really are a lot of BS selling junks in some sites in the US.
