The invention relates to a method for
machining tea, and in particular relates to a method for
machining flower-fragrance
black tea in a low-temperature compounding mode. The method comprises the following steps: spreading to cool high-fragrance type oolong tea with two to three fresh leaves on one
bud as a
raw material, finely manipulating the
green tea leaves, kneading, thinly spreading, fermenting at high temperature and low
humidity, and
drying so as to obtain coarse tea; appropriately selecting to remove peduncles and pieces, highlighting the fragrance and thus accomplishing the
machining. According to the flower-fragrance
black tea machined by using the method, the
weight loss of the green leaves in the
machining process can be controlled, and the
machining time is shortened, particularly under poor weather conditions; fragrant substances such as flower and fruit fragrance of alcohols, alkenes, esters and ketones are added, and the content of
benzyl cyanide with pungent
odor, indole and main fragrant substances, namely,
nerolidol, in oolong tea, are increased, so that the fragrance and the
taste quality of the tea are improved, and then the quality of the
black tea is improved. Sensory evaluation on the finished tea shows that the finished tea is fat, strong, compact, black and tender in appearance, tea tips are visible, the fragrance is strong and heavy, the fragrance of flower and fruit appears, the taste is fresh and mellow, the bottom of a cup has the flower fragrance, and the quality is superior to that of black tea manufactured by using the conventional method.
