Technological process of Liubao tea

Liubao Tea, a kind of black tea, is produced in Liubao Town, Wuzhou, China, and enjoys a high reputation at home and abroad. It is characterized by red, thick, aged and mellow, and has a unique areca nut aroma. The older, the better. The following is the technological process of Liubao tea that I have compiled for you. I hope it helps you!

Picking process

In the past, the primary production of Liubao tea was manually operated by farmers, and the standard 1 bud 3, 4 and 5 leaves were picked. The preliminary production method is: "after picking tea leaves, put them in boiling water to soften them, put them in reeds for about five minutes, press them with wood until the tea leaves curl to a certain extent, then bake them with fire, dry them, steam them to soften them, and put them in reeds for sale." 1937 "Guangxi Specialty Records" contains: "Picking tea during the day, putting it in a basket, and frying it in a pot at night is extremely soft. When the tea leaves are slightly gelatinous, extract them, rub them with utensils before freezing, and the leaves will become smaller and smaller when cooked, and then bake them with low fire. Turn black into tea. "

Initial production process

Fixing-rolling-retting-re-rolling-drying. The primary processing technology of Liubao tea is: fresh leaves are mostly 3 or 4 leaves 1 bud, which are harvested during the day and processed at night. The pot temperature of Liubao tea is 160℃, with 2-2.5 kg of leaves per pot and 7.5 kg of leaves per pot by the water-removing machine. After the pot is put away, stir fry first, then stir fry, and then combine the two into one. Young leaves are more boring and less boring, and old leaves are more boring and less boring. Generally speaking, it takes 5-6 minutes to inactivate the enzyme until the bud leaves become soft, the tea stems break and the leaves turn dark green. After spreading and cooling, it can be kneaded, including manual kneading and machine kneading. You can pinch L- 1.5 kg by hand once, depending on the size of the kneader.

Duplication process

Screening and shaping-stalk selection-stacking-cold fermentation-drying-steaming-stepping on baskets-cooling and aging. The twisting of Liubao tea is mainly plastic, supplemented by cell damage, and the leaf damage rate can be as high as 40%. When kneading, the pressure should be moderate, and the process is roughly as follows: light kneading-light pressing-slightly heavy pressing-light pressing-light kneading, and then deblocking after kneading. Generally 1-2 grade tea should be kneaded for 40 minutes, and tea below grade 3 should be kneaded for 45-50 minutes. After rolling, retting is carried out, that is, the tea blank after rolling is put into a basket or piled on a bamboo pole for retting and fermentation. This is the key process to determine the color, aroma and taste of Liubao tea. The stacking height is 3-5 cm, the wet tea blank is about 15 kg per basket, the stacking time is longer than 15 hours, and the temperature of the tea stack is generally about 40℃. When the temperature is higher than 50℃, the velvet will burn, and attention should be paid to the heat dissipation during the velvet retting process. During retting, the temperature is low, that is, the tea blank is dried to 50% to 60% with a fire temperature of about 60℃ before retting. After retting and fermentation, the tea leaves will be slightly loose, and they should be re-kneaded for 5-6 minutes. Liubao tea drying is also divided into wool fire and foot fire twice. The traditional way is to spread the leaves in a tea drying pot (drying cage) about 3.3 cm, and it is best to dry them with loose fire at 80-90℃, stirring once every 5-6 minutes, drying until 60% to 70% dry, and then baking for half an hour, that is, fully firing at 50-60℃, spreading the leaves with a thickness of 6.6 cm, and drying for 2-3 hours.

refining process

Firstly, the raw tea was humidified by cold fermentation, and the water content reached 12%. Retting for 7- 10 days to make up for the deficiency of primary fermentation. When the water content of tea leaves is about 10%, that is, steaming for half an hour and Ye Quan is soft, the water content of leaves reaches 15%- 16%. The traditional method of making tea is to steam and pile it for 20-30 days, because of the damp-heat effect of these piles. Further promote the change of tea composition. Due to the non-enzymatic oxidation of tea polyphenols, theaflavins, thearubigins and other colored substances are constantly increasing, which makes its color, fragrance and taste stronger and achieves the' unique quality style' of Liubao tea.

Cold aging

The quality of Liubao tea should be old, and the older the better. Cold curing is an indispensable and important link in the production process. Generally, it is piled in baskets, stored in a cool mud bin, and then shipped out for sale the next year, forming a special style of Liubao tea. Therefore, after steaming in summer, the finished Liubao tea must be drained to reduce the leaf temperature, and then stacked in a cool and humid place for aging. About half a year, the soup turns red and tastes cold and astringent, forming the quality characteristics of Liubao tea.

packing method

Liubao tea is generally packed in traditional bamboo baskets, which is beneficial to the continuous transformation of tea contents during storage, making the taste mellow, the soup color deeper and the old fragrance exposed. In order to facilitate storage, Liubao tea is also pressed into blocks, bricks, coins, columns and bulk. Its quality characteristics are: dark brown and smooth color, especially resistant to brewing, reddish brown leaves.
