Study on the technology of traditional oolong tea in southern Fujian

Oolong tea is a semi-fermented tea, mainly produced in Wuyishan area of Fujian, followed by Minnan area of Fujian and Chaoshan area of Guangdong. The processing method of oolong tea is very different from that of black tea and green tea. It has the following requirements:

(1) Tea should not be picked too early or too tender;

(2) Oolong tea must be dried;

(3) adopting the technology of combining "turning green" with "cooling green" to make the tea reach the semi-fermentation level;

(4) The baking process of oolong tea is particular. Oolong tea is a semi-fermented tea between green tea (non-fermented tea) and black tea (fully fermented tea). Oolong tea has two kinds: strip tea and hemispherical tea, and hemispherical tea needs kneading.

Fujian Wuyi Rock Tea, Guangdong Phoenix Narcissus and Taiwan Province Wenshan Baozhong Tea belong to strip oolong tea. Basic technological process (Wuyi rock tea): drying → cooling → drying → deactivating enzymes → kneading → drying.

Tieguanyin in Anxi, Fujian Province, and frozen top oolong tea in Taiwan Province Province all belong to hemispherical (spiral) oolong tea. Basic technological process (Minnan oolong tea): drying → cooling → drying → deactivating enzymes → rolling → rough fire baking → wrapping → boiling → drying.
