Shengcha pu’er appears to be and tastes in one other method from its darkish colour cousin, shu cha pu’er. However moreover it’s known as a pu’er. Although it is a common product nowadays, all by means of antiquity, it had on a regular basis been purchased as the material for producing darkish tea.
We have categorised shengcha as a evenly oxidised tea, within the an identical class as white tea, and however all collectors of extreme worth shengcha would want the tea flip darkish gracefully to excel in prime quality. Which implies they anticipate a shengcha to develop to be a darkish tea, within the an identical 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 a wonderful pu’er.
It’s a Mouldy enterprise
Whether or not or not it is induced post-fermentation ( aka oudui — 漚堆 ) in stylish 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 completely understood in scientific phrases. Nonetheless, it has on a regular basis been clear that microbial actions are important contribution to the final word bio-chemical character. These microbes are largely frequent fungal organisms.
A gaggle of scientists in Taiwan tried to hunt out out what it is in high-quality pu’er that render its good tastes and nicely being outcomes. They gathered among the many best merchandise, along with some terribly pricey and most wished standard renowned shengcha matured for 25 years, to analyse their constituents. Basing on the analysis, they tried to duplicate among the finest pu’er inside the lab and made some flooring breaking finds.
A macroscopic {photograph} of streptomyces — some strains are sometimes referred to as frequent mould — grown in a lab. Such bioactivities happen in rather a lot a lot much less seen scale inside the darkening of pu’er, be it shengcha or shu cha. Nonetheless, within the occasion you see your remaining 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 pretty names to evidences of such malpractices. Silver flower, gold flower and so forth are hoaxes. They’re each parroting, dishonest, or attempting to influence themselves that their fouled product is superior.
54 strains of moulds and micro organism had been acknowledged inside the matured pu’er teas. They took these 54 completely completely different microbes each to ferment a batch of freshly picked tealeaves, thereby making 54 pu’er teas each from one express strand of microbe. In a single different phrase, they executed for the first time in historic previous 54 completely completely different pu’er darkish teas with precisely chosen variations of microbes. They analyzed the merchandise and let the tasters type them. They concluded that 15 of the microbes had been related to good type and nicely being contributing contents.
42 days of Fermentation vs 25 years of Maturing
The catch is, they’ve fermented these leaves for below 42 days, and their nicely being content material materials and nicely being capabilities each match or exceed the pricey 20~25 years matured premium grade pu’er cha bings many cases. As for the tasting scores, although the Taiwan scientists have not printed it, I am optimistic that they’ve some aggressive info of the lab-made teas over the pricey teas. That is on account of usually of various tea lessons, quantity of nicely being elements is rigorously related to type.
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 so forth and concluded that the lab fermented teas elevated a few cases than these of the current tealeaves. What they didn’t say was that additionally they’re each just about nearly as good as or, in some options, many cases over that of the pricey teas. We 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 quite a few strains of microbes
unit= mg/g dw
The microbes had 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 an identical current tealeaves that the scientists used to offer the lab pu’ers. Phrase that among the many strains, notably Y11 and R9, produce polyphenols that amount to over 3 cases that of the current leaves.
Exact manufacturing pu’ers should vary, given that current leaves proper right here, detected to have 10 mg/g of polyphenols, seems to be of a low polyphenol cultivar and are very rather a lot grown leaves. Normally most completely different cultivars picked at or near the tip should have a dry weight content material materials of 18~33 mg/g. It is seemingly that the Taiwanese scientists adopted a secret rule in higher worth pu’er manufacturing — to pick out larger leaves and/or later seasons for the analysis. It is broadly believed inside the commerce that such picks for higher worth pu’er teas render superior tastes.

Nicely being Outcomes of Pu’er Tea
Although many additional analysis are wished to confirm its salutary effectiveness, consuming of pu’er has been confirmed to cut back LDL ( low-density lipoprotein, i.e. unhealthy cholesterols ) ranges. Decreasing of LDL may also be a way of stopping cardiovascular sicknesses. It might need been the affect of the extreme stage of polyphenols, or some contribution from the naturally occurring statin in pu’er.
In one other analysis, scientists discovered a polyphenol matter unidentified elsewhere nonetheless solely in pu’er tea. They title it puerrin. It’s among the many essential constituents inside the polyphenols amount in pu’er , which has found to have elevated dramatically all through post-fermentation by the Taiwan scientists. The way in which through which puerrin carry out inside the human physique has however to be further studied.

The lab made puers are code-named with the precise strains of microbes each from the three pu’ers on the best of the guidelines. We need not disclose publicly the names of these 3 teas involved since they’re terribly extreme worth collector objects. The preliminary Y denotes a stress of microbe from an genuine shengcha that has darkened by the use of rising outdated. R for that from a shengcha-shu-cha combine. It is also important to note that often the post-fermentation for pu’ers closing for about 60~90 days instead of 42.
One different group of scientists ponder theabrownins, the an identical group of provides in aged black tea and exists in minute parts in numerous teas could be the set off. As soon as extra, rather a lot analysis is required for theabrownin.
Practicality ( or fairly indolence ) of frequently 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.
Aside from scientific findings, the one most significant nicely being benefits of pu’er is its light and easy character (shu cha, or well-darkened shengcha) when steeped at common energy, so one has a darkish however light 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, will likely be diluted when too sturdy and will likely be left inside the pot for the day with scorching water and nonetheless holding on a continuing type profile. A tea tolerating as such spoils its drinker for inattentiveness. This vogue anyone will likely be consuming your complete day an excellent drink whereas having enjoyable with tea’s widespread nicely being benefits.
That is to not say, nonetheless, care and experience won’t be wished for the correct cup of pu’er.
Between Shengcha and Shu Cha
What the scientists did inside the lab won’t be popularly employed by pu’er producers however, nonetheless right post-fermentation has on a regular basis been geared within the course of attracting the enlargement of the required microbes. The tea retailers who invented the tactic could not take note of the nicely being benefits this “darkening” course of brings to the tea, nonetheless the lab tea info have confirmed this generally is a good course of for bettering the type and nicely being values of this taken as a right drink.
Finer shengcha has its enchantment with a mode profile of a rather a lot wider gamut, and its property would not be the an identical by the use of its quite a few phases of darkening. Consistent with this Taiwan analysis, nonetheless, their matured variations do not current as rather a lot nicely being giving potential.
Brisker shengcha, nonetheless, should be understood as a white tea. Not solely does it type utterly in one other method however as well as its nicely being implications should even be understood as that of white teas For people 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 12 months and circumstances of storage.
Manufacturing Processing for the Darkening of Pu’er tea will Change
The Taiwan analysis made such an unimaginable affect on the planet of pu’er that subsequent analysis had been made. A lot of factories have even prepare high-tech post-fermentation processing with isolated strains of microbes, aiming to duplicate extreme price productions with out the guess-work, have an effect on of ambient circumstances and intensely specialised labours.
