The first monograph on tea science in China and the first monograph on tea in the history of the world is "The Classic of Tea" written by Lu Yu. Explain the tea in detail
One of important process for the black tea is fermentation, use the suitable fermentation machine could control good quality of black tea.
Different green tea drying methods, different machines, green tea strands, and green tea aroma are all different, welcome your contact for more details.
The completion of Pu-erh tea can be summed up in three words: fast, uniform and totally.
"Fast" refers to raising the leaf temperature rapidly (generally within 1 to 2 minutes) to 85°C for about 3 minutes, since 85°C is the critical temperature for enzyme inactivation.
"Uniform" means that the temperature is as uniform as possible, and the fixing is uniform.
"Totally" means to kill the fresh leaves thoroughly.
Regarding the active enzymes in tea, there is such a set of temperatures: when the temperature reaches 35 °C, the catalytic effect of the enzyme will double for every 10 °C increase in temperature; at 52 °C, the activity of polyphenol oxidase is the highest; at 85 °C, Enzyme inactivation.
Therefore, the best way to tea fixation is to raise the temperature quickly, so that the leaf temperature reaches 85 °C, and the tea fixing is completed in a short time, the active enzymes are killed as soon as possible, and the aging potential of Pu'er tea is preserved as much as possible.
So what happens when the temperature is too high and too low?
If the temperature is too high, it will cause a lot of cracking of glycosides, which will also reduce the aging potential; if the temperature is too low, not only will the low-boiling grassy flavor not volatilize, but also lead to the occurrence of pre-fermentation, thereby destroying the aging potential of Pu-erh tea.
Therefore, when we fixing the fresh leaves of Pu-erh tea, it is best to accurately control and record the leaf temperature. The quality of the Pu-erh tea produced in this way is more guaranteed, especially in the later ageing process, the impact will be greater and greater.
