【Background technology】
The Chinese yellow tea origin Ming Dynasty relaxes according to perhaps secondary《Tea is dredged》It records within (1579) away from the modern history for having more than 400 years.According to
Passing yellow tea is developed from Green Tea Processing error, belong to Chinese six big teas (i.e. green tea, yellow tea, black tea, black tea,
One of white tea, oolong tea).History records are said：It " cares for and is not good at preparation method in that mountain, just roasted in food pan fire firewood, not and go out kettle, leaf is shrivelled
Ju may be used.And huge bamboo is made with bamboo, multiply heat and just store, though there there are green branch purple bamboo shoot often just to entrust to be yellow, only supplies lower food, why bears product bucket." namely
Say tea grower at that time will not the tea growers of tea making, especially North of Yangtze River fry roasting fresh tea with the iron pan cooked, use cloth after taking the dish out of the pot
On packed, tea is rubbed with the hands carefully by the way of hand rubbing, then is stored for drink in thick bamboo tube.Since tea making is too slow in this way, the time
It is too long, but not what skill, the tea worked it out all are yellow, having or even black or paste, the soup looks bubbled out
It is brownish red entirely, therefore is otherwise known as " bright red soup " " greatly grab ", Pekinese is called " stall tea ", and people from Laiwu in Shandong province returns it and take
Interesting being named as " old dry dry ", here it is the origins of " the yellow big tea in Huoshan " recorded in history records, pass on always so far.
Yellow tea in process, makes polyphenols carry out being converted to solable matter, while isomerization occurs, makes Huang
The dense alcohol of tea millet paste flavour.May additionally facilitate breaks down proteins simultaneously is amino acid, and Starch Conversion is soluble saccharide, sugar and amino acid
