I saw Cloud just post some links on HK forum about his recent articles on a new paper magazine. One article was about green tea puerh and I think it may be useful to post some of the key points he made in the article here as well.
Tuition fee tea (abridged)
Most of these tea is aromatic "green tea" like puerh. However, as these teas age, they will loss their aroma or even become inferior in taste.
Another mistake inexperience puerh drinkers would make is looking for intact leaves on the cake or whether there are 2 leaves in a bud, but all these have nothing to do with taste of the tea. And most of the time this type of tea would taste rather bland as there was insufficient rolling during the processing of the leaves to preserve the attractiveness intact leaves on the cake. Correct rolling is very important, not enough, it would taste rather bland, too much it would be too bitter.
