With all due respect, there is no such thing as raw pu erh. My family is in the tea plantation business for four generations. I have worked in our plantation for over 20 years. May be you are refering to green pu erh. It's colour looks like green tea. But that is the biggest misconception of tea outside China. Many, many decades ago some influential tea merchants who did not fully understand tea were telling people of the world the main difference between green tea, oolong tea, black tea, and white tea. Now every book, and every website uses the same definition--the major difference is in the fermentation of the tea leaves. However, this definition is extremely over simplified, misleading and mostly incorrect. The major difference between the different teas are that they all comes from different tea plants. Teas like apples, peaches and pears have many, many different varities. Some varities are perfect for green teas, while others are great for white teas, and still others are ideal for red teas (mostly refer to as black teas in the West). This white tea varities will never be used to make green teas and vice versa. Even in the green tea family there are countless sub-varities. This is only true in China, and Taiwan. India is now growing green tea, and white tea, but their altered varities work differently, and can never be as superior as the thousands of green teas in China.
For people who are truely interested in the finest teas in the world, they should visit China many famous tea garden (plantations) the next time they are in the country. Most plantations welcome foreigners for visits.
I do agree that zheng shan xiao zhong (lapsang souchong) is a good tea if people could find it at a fine tea merchant--it is not an easy tea to locate in North America. And the Koo Loo tea is very nice. It has a floral aroma. But again this tea is not catagorized as green. In its purest classification, this is a fully-fermented red tea; however, in the West, red tea is consider black tea. In North America, for the sake of simplication, yellow teas, and red teas do not exist at the current time.
In most case, you seem very knowledgeable about tea. It took me many decades to truely understand the nuances, and I was literally borned in a tea plantation in Fujian.
