Analysis is understood：Naturally the sample displayed, substance classes are more, and Ester content reaches 28.95%, significantly larger than
Esters content in cluster tea sample；And cluster tea sample, based on fragrance component, other compounds contents are relatively low.
All using monoterpene and sequiterpene as half in the terpenes and its derivative of each sample, but ingredient is inconsistent, but with a variety of
The form of isomers exists.In the sample of gross tea is displayed naturally, guaiene is characteristic aroma substance, is made it have certain
Radix Aucklandiae.The shared ingredient of cluster tea sample is most, reaches 9, the content of terpenes has comparative advantage, and species is enriched, with anti-
The content highest of formula-carypohyllene, based on trans-cloves alkene.
In Pu'er tea cluster tea technique provided by the invention, more aromatic esters, the substances such as carbohydrase participate in refrigeration and increase
Fermentation process after fragrant mechanism, makes Pu'er tea more active；Stablize the ageing of Pu'er raw tea later stage, to the temperature humidity of storage space
Requirement it is relatively low, average family preferably storage.Meanwhile the transformation period shortens, it is no longer necessary to the basic transition phase of 5 years, from the
Start to be directly entered aging period within 3 years.Pass through the bright gold of millet paste of tealeaves prepared by Pu'er tea cluster tea technique provided by the invention
Huang, tea impervious power are strong, mellow in taste, elegant fragrance, and newly picked and processed tea leaves sentimental taste is few, does not injure one's stomach, the irritation without common new Pu'er,
Storage starts perfume (or spice) after 2 years and sinks to soup, reaches the tidemark of perfume unification.
In addition, shown referring to Figures 1 and 2, by the mountain peak tea cluster tea tenacious tracking of 12 years, it then follows a number grade tea history deposit data and
Mountain peak tea newly picked and processed tea leaves change procedure arranges, and has respectively obtained the life tea perfume gas obtained using Pu'er tea cluster tea technique provided by the invention and has become
Change trend and the Pu'er tea life tea perfume gas conversion trend obtained using common process.As can be seen from the figure：Using cluster tea technique
Fragrance conversion with not using tealeaves that cluster tea technique obtains moves towards that the time difference opposite sex is very big, and the metastatic of fragrance also has
It is variant.
Although an embodiment of the present invention has been shown and described, it will be understood by those skilled in the art that：Not
In the case of departing from the principle of the present invention and objective a variety of change, modification, replacement and modification can be carried out to these embodiments, this
