Shengcha pu’er appears and tastes differently from its darkish colour cousin, shu cha pu’er. Nevertheless it’s additionally known as a pu’er. Although it is a common product lately, all by means of antiquity, it had always been purchased as the material for producing darkish tea.
We now have categorised shengcha as a flippantly oxidised tea, within the similar class as white tea, and however all collectors of extreme value shengcha would want the tea flip darkish gracefully to excel in top quality. That means they depend on a shengcha to alter right into a darkish tea, within the similar class as shu cha, and as people in antiquity had understood the tea.
Let’s transcend labelling and take a look on the character of this “darkening” course of and what determines an excellent pu’er.
It’s a Mouldy enterprise
Whether or not or not it is induced post-fermentation ( aka oudui — 漚堆 ) in modern darkish tea processing, or “pure” post-fermentation as inside the historic course of, the darkening of pu’er is sophisticated. Its nature is however to be utterly understood in scientific phrases. Nonetheless, it has always been clear that microbial actions are important contribution to the last word bio-chemical character. These microbes are largely frequent fungal organisms.
A bunch of scientists in Taiwan tried to go looking out out what it is in positive high quality pu’er that render its good tastes and nicely being outcomes. They gathered a couple of of the best merchandise, along with some terribly expensive and most needed typical renowned shengcha matured for 25 years, to analyse their constituents. Basing on the analysis, they tried to duplicate the best pu’er inside the lab and made some flooring breaking finds.
A macroscopic image of streptomyces — some strains are sometimes referred to as frequent mould — grown in a lab. Such bioactivities happen in lots a lot much less seen scale inside the darkening of pu’er, be it shengcha or shu cha. Nonetheless, once you see your closing product having that alongside along with your naked eyes, it means your tea has not been accurately processed, handled, packaged or saved. Certain people inside the commerce give beautiful names to evidences of such malpractices. Silver flower, gold flower and plenty of others are hoaxes. They’re each parroting, dishonest, or making an attempt to steer themselves that their fouled product is superior.
54 strains of moulds and micro organism have been acknowledged inside the matured pu’er teas. They took these 54 utterly completely different microbes each to ferment a batch of freshly picked tealeaves, thereby making 54 pu’er teas each from one specific strand of microbe. In a single different phrase, they executed for the first time in historic previous 54 utterly completely different pu’er darkish teas with precisely chosen variations of microbes. They analyzed the merchandise and let the tasters model them. They concluded that 15 of the microbes have been related to good model and nicely being contributing contents.
42 days of Fermentation vs 25 years of Maturing
The catch is, they’ve fermented these leaves for lower than 42 days, and their nicely being content material materials and nicely being capabilities each match or exceed the expensive 20~25 years matured premium grade pu’er cha bings many events. As for the tasting scores, although the Taiwan scientists have not revealed it, I am constructive that they’ve some aggressive info of the lab-made teas over the expensive teas. That is because of usually of various tea courses, quantity of nicely being components is fastidiously related to model.
The scientists measured a few nicely being contributive indicators, such as a result of the content material materials for statin, GABA, polyphenols, radical scavenging actions and plenty of others and concluded that the lab fermented teas elevated a few events than these of the up to date tealeaves. What they didn’t say was that additionally they’re each just about nearly as good as or, in some factors, many events over that of the expensive teas. We now have used their figures to make these graphs as an example the aim.
Tea polyphenols content material materials, at 42 days of publish fermentation by different strains of microbes
unit= mg/g dw
The microbes have been code-named by a straightforward amount referring to which premium pu’er the scientists extract them from. The administration info is detected from the similar up to date tealeaves that the scientists used to offer the lab pu’ers. Observe that a couple of of the strains, notably Y11 and R9, produce polyphenols that amount to over 3 events that of the up to date leaves.
Exact manufacturing pu’ers must fluctuate, given that up to date leaves proper right here, detected to have 10 mg/g of polyphenols, seems to be of a low polyphenol cultivar and are very lots grown leaves. Often most completely different cultivars picked at or near the tip must have a dry weight content material materials of 18~33 mg/g. It is likely that the Taiwanese scientists adopted a secret rule in elevated value pu’er manufacturing — to decide on greater leaves and/or later seasons for the analysis. It is broadly believed inside the commerce that such picks for elevated value pu’er teas render superior tastes.

Effectively being Outcomes of Pu’er Tea
Although many additional analysis are needed to confirm its salutary effectiveness, consuming of pu’er has been confirmed to cut back LDL ( low-density lipoprotein, i.e. unhealthy cholesterols ) ranges. Lowering of LDL may also be a way of stopping cardiovascular diseases. It might need been the influence of the extreme diploma of polyphenols, or some contribution from the naturally occurring statin in pu’er.
In one other analysis, scientists discovered a polyphenol matter unidentified elsewhere nevertheless solely in pu’er tea. They establish it puerrin. It’s doubtless one of many primary constituents inside the polyphenols amount in pu’er , which has found to have elevated dramatically all through post-fermentation by the Taiwan scientists. One of the best ways puerrin carry out inside the human physique has however to be further studied.

Unit = ng/g dw
The lab made puers are code-named with the precise strains of microbes each from the three pu’ers on the best of the itemizing. We do not want to disclose publicly the names of these 3 teas involved since they’re terribly extreme value collector devices. The preliminary Y denotes a stress of microbe from an distinctive shengcha that has darkened by means of rising previous. R for that from a shengcha-shu-cha combine. It is also important to note that often the post-fermentation for pu’ers remaining for about 60~90 days instead of 42.
One different group of scientists take into consideration theabrownins, the similar group of provides in aged black tea and exists in minute parts in several teas would be the set off. As soon as extra, lots analysis is required for theabrownin.
Practicality ( or fairly indolence ) of regularly use
Inside the Taiwan analysis moreover they found extreme capabilities of the lab teas in radical scavenging, i.e. anti-oxdative actions. That’s in agreements with the outcomes of some completely different analysis on essentially the most cancers prevention of pu’er tea.
Furthermore scientific findings, the one most important nicely being benefits of pu’er is its mild and easy character (shu cha, or well-darkened shengcha) when steeped at affordable energy, so one has a darkish however mild enough drink at any time of the day all day prolonged with out the need of milk or sugar. The tea stands correctly to abusive or careless infusion practices, shall be diluted when too sturdy and shall be left inside the pot for the day with scorching water and nonetheless holding on a relentless model profile. A tea tolerating as such spoils its drinker for inattentiveness. This style anyone shall be consuming the complete day a pleasant drink whereas having enjoyable with tea’s frequent nicely being benefits.
That is to not say, however, care and talents often should not needed for the appropriate cup of pu’er.
Between Shengcha and Shu Cha
What the scientists did inside the lab is not going to be popularly employed by pu’er producers however, nevertheless appropriate post-fermentation has always been geared in path of attracting the growth of the required microbes. The tea retailers who invented the strategy might not think about the nicely being benefits this “darkening” course of brings to the tea, nevertheless the lab tea info have confirmed this generally is a good course of for enhancing the model and nicely being values of this taken without any consideration drink.
Finer shengcha has its enchantment with a method profile of a lots wider gamut, and its property would not be the similar by means of its different ranges of darkening. Primarily based on this Taiwan analysis, however, their matured variations do not current as lots nicely being giving potential.
Brisker shengcha, however, must be understood as a white tea. Not solely does it model solely differently however as well as its nicely being implications additionally must be understood as that of white teas For a lot of who’re additional acutely aware of TCM nature of tea, a brisker shengcha is each chilly or cool in its TCM character, relying of finish processing and yr and conditions of storage.
Manufacturing Processing for the Darkening of Pu’er tea will Change
The Taiwan analysis made such an superior have an effect on on the planet of pu’er that subsequent analysis have been made. Only a few factories have even prepare high-tech post-fermentation processing with isolated strains of microbes, aiming to duplicate extreme value productions with out the guess-work, have an effect on of ambient conditions and very specialised labours.
