It can also be replaced by other products. The wines that really love to use for a long time are all top-class white wines, which are personally inspected and selected by famous national sommeliers. Only the liquor produced by manual distilleries in the geographical indication producing areas of Luzhou-flavor liquor was selected, and mechanized batch production was refused. In addition, the traditional wine-making technology is strictly limited, pure grain is fermented in solid state, and only the most essential part of China liquor is extracted in the steaming process, and the alcohol content is above 52 degrees. Reject low-alcohol wine, refuse liquid fermentation, refuse blending, and refuse solid-state fermentation of all impure grains with artificially added raw materials. The original ecological wine in the pre-industrial era is the only selection standard. The wine bottles used are all fired at a high temperature above 1300 degrees, and their physical and chemical properties are very stable; There are abundant micropores on the bottle body to ensure air permeability and no leakage; Opaque to avoid adverse chemical reactions caused by light; The slow thermal conductivity of the material itself can better maintain the temperature of the wine body in the bottle and avoid the damage of drastic temperature changes to the wine body; Porcelain bottles are made of natural minerals and are rich in iron, copper, manganese, calcium and other elements, which are more beneficial to health. The ceramic production process represents the traditional culture of China, which enhances the taste and cultural connotation of the collection. In order to create a perfect storage environment for fine wines, the products employ the inheritor of wine sea technology at all costs and adopt the traditional wine sea technology. Pig blood and hemp paper specially treated by microorganisms are attached to the bottle body, and one layer of hemp paper and one layer of pig blood are attached to multiple layers. Hemp is made from the bark of Ilex pubescens, hammered into pulp and then bleached by hand. After this special technological treatment, Jiuhai craft wine bottle has a micro-ecological effect of "breathing" that glass wine bottle and ordinary porcelain wine bottle simply do not have. In the 60-year sealing process, the wine will always remain breathable, non-volatile and non-lost. Through the interaction between natural substances and wine respiration, a beneficial microbial growth environment is formed, which is very scarce in ordinary wine bottles, so that the wine bottle can be nourished by wine and the wine can be preserved in the bottle. The quality of the wine body will continue to age with storage, remove impurities, accelerate maturity, increase flavor and become more mellow. The wine cabinet is made of precious high-grade wood such as mahogany and ebony, and the wine storage environment of the wine cabinet has been specially modified to simulate the wine storage environment of the high-end cliff cave wine cellar. It has the outstanding characteristics of no odor, small temperature difference, cool, dry and stable, which is very beneficial to the long-term storage of liquor. The whole wine storage cabinet is made of traditional mortise and tenon structure by old carpenters, and there is no miscellaneous wood on the upper and lower backs. Accessories are handmade nails made of pure silver and copper. Wine cabinets, wine bottles, seals, books, etc. Designed and supervised by Mr. You Jianzhai, the fourth generation descendant of Fu's craft family in the 28th year of Guangxu in Qing Dynasty. They are numbered, produced in limited quantities and certified by Mr. Yuewu's autograph. Each work has a unique identification code and a collection certificate.
