Embodiment 1

[0031] A processing method of Guire No. 2 dark tea, comprising the steps of:

[0032] (1) Material selection: choose Guire No. 2 fresh leaves with one bud and two leaves or one bud and three leaves without pests and diseases as raw materials, spread the picked Guire No. 2 fresh leaves in a dustpan, and dry the surface moisture;

[0033] (2) Withering: spread the fresh leaves of No. 2 Guire on the withering bed, the spreading thickness is 0.5cm, the withering temperature is 20°C, the water loss rate is controlled at 35%, and the withered leaves are obtained after withering for 10 hours;

[0034] (3) Finishing: put the withered leaves into the finishing equipment for finishing, the finishing temperature is 180°C, when the leaves are stabbed or the tea stems are folded continuously, the green leaves are obtained;

[0035] (4) Kneading: use a tea kneading machine to knead the green leaves, the temperature in the kneading machine is 20°C, lightly press and knead for 30 minutes and ...

Embodiment 2

[0042] (1) Material selection: choose Guire No. 2 fresh leaves with one bud and two leaves or one bud and three leaves without pests and diseases as raw materials, spread the picked Guire No. 2 fresh leaves in a dustpan, and dry the surface moisture;

[0043] (2) Withering: spread the fresh leaves of Guire No. 2 on the withering bed, the thickness of which is 0.8 cm, the withering temperature is 23° C., the water loss rate is controlled at 40%, and the withered leaves are obtained after 12 hours of withering;

Abstract

The invention provides a processing method of Guire 2 dark tea. The processing method comprises the following steps: (1) material selecting; (2) withering; (3) fixation; (4) rolling; (5) solarizing; (6) pile fermentation; (7) steaming; (8) pressing; and (9) storing and converting. The processing method selects fresh leaves of Guire 2 as raw materials, has novel and unique design and processing technology, simple production technology and relatively low cost and can improve the grade of dark tea, and the prepared dark tea has unique mouthfeel and superior quality. The solarizing step is arranged additionally between the rolling step and the pile fermentation step, so the rolled tea subjected to ultraviolet radiation of the sun has richer and purer fragrance and fresher and brighter color and luster.

Description

【Technical field】 [0001] The invention relates to the technical field of tea processing, in particular to a processing method of Guire No. 2 black tea. 【Background technique】 [0002] Guire No. 2 is a new variety of tea tree selected and bred by the Experimental Station of Guangxi Tropical Crops Research Institute. It was registered in 2006, and the new variety registration number is (Gui) Deng (Tea) 2006010. Guire No. 2 has strong yield and wide adaptability. It has the characteristics of strong buds and leaves, good tenderness, extra hairy buds, and rich contents. The content of water extract in fresh leaves is 49.8%, and tea polyphenols It is 29.6%, free amino acid is 3.7%, and caffeine is 4.4%. [0003] Dark tea (dark tea) gets its name because the appearance of the finished tea is black. Black tea belongs to one of the six major tea categories and is a post-fermented tea. The main production areas are Sichuan, Yunnan, Hubei, Hunan, Shaanxi, Anhui, Guangxi and other pl...
