Construction steps of white wine cellar pool (the difference between Maotai-flavor liquor, Luzhou-flavor liquor and Fen-flavor liquor cellar pool)

The article reference comes from the author's website.

Summary: Generally, Daqu liquor fermentation containers are underground loose-mouthed, which is convenient for heat preservation and operation. The volume of traditional fermentation vessels is generally 6 ~ 100 m? . In order to facilitate mechanized fermentation, there is an increasing trend. At present, large fermenters are 20~40m? . Because of the different flavor of liquor, the size and material of Daqu fermentation pool are also different.

Luzhou-flavor liquor includes Wuliangye, LU ZHOU LAO JIAO CO.,LTD, Gu Jing Distillery, Yanghe Daqu and Jiannanchun.

(1) Traditional cellar: Traditional cellar is made of yellow mud. Average volume 10m? , with 6~8m? Out of kindness. The length-width ratio is 2: 1, and the depth is 1.5m, so it is advisable to have a small mouth at the bottom. There is generally no drain at the bottom of the cellar. In order to maintain the old cellar.

(2) Artificial new pits: Some famous wineries have newly-built pits, with the aspect ratio of (1.2-1.4):1,the depth of 1.6- 1.8m and the volume of/kloc-.

The specific process and requirements for cellar building are as follows:

① Pit building materials: It is composed of high-quality mud, pit skin mud, old pit mud, old pit yellow water, Daqu powder, bamboo nails and some hemp fibers. It is forbidden to use materials such as square bricks, bar stones and cement.

② Pit drainage foundation: Choose a pit foundation with suitable topography, soil quality and soil quality, and it is best to use yellow mud with strong viscosity as soil parent material for digging. Generally speaking, containers are arranged according to the terrain. So as to mechanize the brewing operation.

③ Building the cellar wall: build the cellar wall with fresh and sticky yellow mud that has not been dried, and build it firmly. The vertical ridge width of pit foundation is 1.5m, and that of flat land is1m; The horizontal ridge (length) thickness at the bottom of the pit is 1m, and the flat land is 65cm. It is also necessary to use wallboard to master the dense wall with a certain inclination. The transverse ridge between pits must be not single-walled, but double-walled (referring to the thickness), and it is tightly built when filling mud. If the friction of the wall is reduced at will, it will easily collapse when used.

④ Nailing the cellar: nail the cellar wall to15 ~ 20 cm; The pit nail spacing is 10cm. After the pit nails are laid, the bevel angle is 45 ".

⑤ Pit wall: After the nail head of the pit is wrapped with ramie, the pit mud is transported to the bottom of the pit, and it is slammed against the pit wall and the guest bottom, leaving 1 nest-shaped yellow puddle in the corner of the pit bottom. After the new pit is completed, it should not be used in bulk to avoid cracking of pit mud, so it should be used immediately.

Qing Xiang-style wines include Fenyang King Wine and Tongshan Shao.

(1) underground cylinder: generally, the diameter of underground cylinder is 0.7~0.9m, the height is 1~ 1.6m, and the center distance between two adjacent cylinders is1m.

(2) Cement cellar: The cellar surface made of ceramic tile veneer, ceramic tile veneer, terrazzo or cement polishing and waxing is preferred. The cement used is high-grade cement or acid-resistant cement. Can't use ordinary brick veneer. Usually there is a slope of 3% at the bottom of the pit, and there is a drainage ditch. Trenches, cast iron pipes or acid-resistant plastic pipes are led to wells at the bottom of the pit, and yellow water is lifted and discharged by sewage pumps.

Maotai-flavor liquor includes Maotai and Xijiu.

Generally speaking, pits are made of stone, clay and sandstone, with ceramic tiles or terrazzo on the surface.
