Mydnight,
you posted this elsewhere, but I thought I'll digress from the Mao & Bai discussion here...I think you have asked but not received many reply on whether the Liu Bao Cha tea is good for keeping. The answer is yes if you keep it well. Place the tea in a new earthern jar, and get some clean bamboo charcoal from the local supermarket, or wood ones if you can't find the former. Wrap a few pieces in a cheesecloth and place it in the jar with the tea. Cover the jar but not tightly, and place the jar in a cool place above ground, as it can get humid on that level.
Guangxi Liu Bao is not a pu'er. By definition pu'er has to be produced in the regions of Yunnan using the large leaf varietals from Yunnan, such as the Camellia sinensis var. assamic cv. Yunkang 43 or the cv. Lincang-dayecha. Guangxi liu bao uses a different varietal altogether, which is the Camellia cv. Liubaocha, also the var. pubilimba cv, Liudong-dayecha.
Liu Bao is a Chinese black tea, not a pu'er. A pu'er can be a black tea in broad terms, but technically, it should be considered as a post-fermented tea (which black tea also falls under), and is divided into into 2 broad categories: Speed post-fermentation (also called ageing) by piling, and slow post-fermentation over time.
Under Speed post-fermentation by piling, it is again subdivided into 2 broad categories: wet & dry storage. To encourage further and faster post fermentation, the tea is kept in storage houses with high humidity level. This can be done in 2 stages: once right after the piling and compressing process, and another time by the tea vendors in rented storehouses. The latter fermentation is often not agreed upon by many serious pu'er collectors.
To encourage a more natural albeit slower post fermentation, the tea is picked, fixed on low heat - usually under the sun, compressed and kept in a dry storage house with low humdity and low temperature to slowly take out the dampness in the cake and allow it to age naturally. After this, tea vendors can either put it right back into a wet storage storehouse to kick up the post fermentation - which is very undesirable, and which can be seen on the surface as a white-bluish frost with dark black leaves, or let it age naturally in a dry storehouse, or at the teashop itself.
Liu Bao doesn't do through this tedious process, but it is the forefather of modern day speed post fermentation process, as in late 1960s tea makers from Kunming and Menghai came to Guangxi to study the process of Liu Bao making and applied that on the pu'ers.
There's a new class of pu'er over the last several years that's gainig popularity, I think someone has posted it as green tea pu'er. It is just as what it says. It is a raw pu'er made out of mostly young bud leaves and flushes which many people like. The only serious problem with this sweet delicate tea, is whether it will keep well. You see, the tea is made under high heat fixation, similar to that of a green tea, and green tea doesn't keep for long, even if it uses the Yunnan large leaf varietal. High heat fixation such as hot drum rolling, frying and high heat steaming destroys much of the enzymes in the leaf on which the microbes need to feed on to create the unique flavour of pu'er as we know it. Such green tea pu'er generally lasts a shorter lifespan, and most serious pu'er collectors will advise against collecting these cakes for ageing - they believe that the tea liquor will be sweet, but there would be no nuance, or depths a good pu'er should have.
& sorry Michael - you know what I'm talking about... :")
Danny ps. Hey, I'm observing from the ground too Rebecca, as you have said Mydnight does, do I get some praise too? Puuurty pleeese? :")
