Stored in assorted parts of tea aging effects of

tea's essence merits ​​embodied in the tea market in the amount of important weight. As the product identification of non-standard and immature market, the year of tea has convert difficult to nail a controversial issue. This issue, we invited to the South China Agricultural University, Professor Chen Wenpin for us in 2002, likened with the batch of tea samples, respectively, in Guangzhou,Diesel Womens Jeans, Shanghai, Kunming and Hong Kong after four years in different parts of storage, sensory and physical and chemical quality changes differences.
1, Guangzhou, Shanghai, Kunming and Hong Kong, four places have different climatic conditions?

2, different climatic conditions, storage of tea, changing results?
A: No. We kind of tea, namely A1 (Guangzhou-like), A2 (Shanghai-like), A3 (Kunming-like), A4 (Hong Kong sample), storage of results the emulating table:
Number
Soup
Aroma
Taste
Securinega
A1 (Guangzhou)
Bright orange
Sweet Chen, plum aroma, thick
Chunnong more sweet
Ming green than yellow, soft A2 (Shanghai)
Bright orange
Sweet Chen, Hong darker plum
Chunnong sweet
Red, yellow, more explicit, soft A3 (Kunming)
Bright yellow
Health and Mei Xiang, a light
More bitter
Yellow-green than the afterward, soft A4 (Hong Kong)

As can be seen from the design

:
; (1) soup, and Kunming namely still kind of cache of yellow-green tea, green tea and the soup is virtually customary drying,Diesel Jeans, merely the greatest change was in Shanghai tea-like orange-red tea.
(2) taste and aroma, likewise showed noteworthy distinctions in Kunming, the taste of tea examples stored more prejudiced in like of non-fermented green tea, meantime the other three tea samples have been obvious the post-fermented tea flavor characteristics.
This indicates that different storage conditions, even because the same tea leaves, later the same aging handling storage time, they change is a colossal difference.
This also proves storage time is only a tea aging factors,Diesel Loose Jeans, without thinking other storage conditions such for temperature, humidity, storage time to judge equitable from the quality of tea is unscientific, it is difficult based solely on the sensory quality of tea leaves to determine and verify the storage year.

3, four apt tea aroma components of the difference is reflected in what zones?
A: The tea is a array of volatile aroma composition, aroma and how much content is decisive by the type of the terminal tea-like aroma. A aggregate of 123 test detected mercurial aroma components, which, A1 (Guangzhou) detected 118 kinds of samples, A2 (Shanghai-like) only detected 95 kinds; A3 samples detected in 100 kinds of Kunming, A4 samples in Hong Kong only detected 92 kinds of mercurial components. Instructions stored in different weather conditions, volatile aroma components of tea-like transformation of the results will be different.

4, the final learn results certify?
results show that: (1) storage conditions can significantly affect the aging changes of tea, tea relying solely on sensory difficult to identify the year.
(2) storage is temperature and humidity can be very significant shock on the quality of tea sensory and physical and chemical changes in the speed.
(3) conditions of storage is different,Diesel Skinny Jeans, tea aroma and flavor composition changes significantly different, Chen Hong metaplasia is a technological foundation.
(4) that the storage of ripening tea aging is one important quality of the formation and processing processes, to achieve modernization of tea aging process to improve the evolution of tea manufacture, the merely direction.

5, for the special nature of tea, you have whichever counsel to consumers and businesses do?
A: Because of different temperature, humidity, geographical environment, the latter part of the aging of tea important, it is laborious based solely on the sensory quality of tea leaves to determine and verify the storage year. Today, the duration of five years, Chen has a great digit of tea in the next few years, Chen ten years period ambition gradually renowned tea market, so businesses and consumers, ought have a decisive wisdom of the identification of tea storage, in order to defend their rights.
recommended merchants:
(1) tea should not be also one-sided emphasis on the year, while ignoring the specific storage conditions and technical ingredients and the phenomenon of product quality, this is undoubtedly biased, are possible to cause muddle in the market,Diesel Store, there's tea fraud on the year.
(2) the best in the business and apparently apparent on the production certified by specialists, the specific storage area, storage environment, storage temperature, storage humidity, storage year, so that consumers self-identification.
(3) Technically, suitably increasing the storage temperature and humidity, alternatively elect the appropriate climatic conditions of the district to complete the role-based tea warehousing heat aging process, the abbreviate the ripening period, storage is to reduce prices,New Diesel Jeans 2011, amend processing efficiency has a very important significance.

also gives clients 2 suggestions:
(1) tea is best for tea sweethearts warehousing environment, have some knowing and knowledge, understand about the different climatic conditions, changes in direction and progress of tea, accordingly making it easy to purchase, the better to judge the values of aging, and storage of authenticity.
(2) Tea storage is the same in different locations, deserving to storage is the ambient temperature, humidity and other climatic conditions, differences in the speed of conversion products, aging and quality of the subsistence of exceedingly significant differences in storage is extremely meaningful conditions to decide the speed of aging changes. Therefore, consumers in the evaluation of the quality of tea, must get cracking the substantial sensory tasting justice, not by the
