Method for keeping bottled wine in storage

Abstract

The invention discloses a method for keeping bottled wine in storage, which comprises the following steps: constructing an underground wine room below a ground surface, wherein the underground wine room is at least provided with a group of air vents; a cement ground surface and a brick wall are used; a sand grain layer is at least paved on a used area with more than 10cm in thickness and 0-80% in moisture content; horizontally laying more than one layer of bottled wine to form at least a row; paving the sand graining layer with more than 6cm in thickness on each layer of the bottled wine; controlling temperature in the underground wine room within 10-20 degrees centigrade; and controlling relative humidity within 50-85%; or constructing a plurality of sand grain storage cave with same environment in the underground wine room; and implementing a laying storage method in each sand grain storage cave; when each layer of the bottled wine is laid, the opening of each bottled wine is buried in the sand grain layer. According to the invention, the method is characterized by low cost, simple and convenient operation, natural condition dependence and can stabilize the stored temperature and humidity of the bottled wine preferably.

Description

technical field [0001] The invention belongs to the technical field of fruit wine brewing, in particular to a method for storing bottled wine. Background technique [0002] At present, the storage of wine mainly has two completely different methods of storage in large tanks (barrels) and storage in bottles. This wine storage process is also called tank (barrel) storage and bottle storage. Proper storage promotes the aging of wine, which can increase the depth, breadth and complexity, and increase the value of the wine without losing the basic characteristics of the wine. The improvement of the quality of wine stored in tanks and bottles is directly affected by environmental conditions. A certain temperature and Under humidity conditions, the wine quality can be guaranteed to develop at a normal rate and gradually enter the perfect state. [0003] 1. Temperature: If the temperature is too high, it will cause the wine to mature too quickly, and the taste of the mature wine wi...

AI Technical Summary

Problems solved by technology

[0003] 1. Temperature: If the temperature is too high, it will cause the wine to mature too quickly, and the taste of the mature wine will not be rich and delicate, and it will age prematurely; if the temperature is too low, it will delay the evolution of the wine and stop it, thus losing the meaning of bottle storage

The most important thing in the bottle storage stage is the constant temperature. The change of temperature not only has a bad effect on the wine chemically, but also physically expands and contracts with heat and cold, which will also cause the cork to lose its elasticity, resulting in excessive oxidation, extravasation and accelerated deterioration of the wine.

[0004] 2. Humidity: The wine storage room is too dry, and the outside air will soak into the bottle through the gap of the cork, which will intensify the oxidation of the wine.

[0006] 4. Illumination: The wine cellar for bottle storage needs to be protected from light, because light will affect the aging of wine, light can easily cause deterioration of wine, and ultraviolet radiation can cause oxidation reactions

Tank storage and barrel storage can be completed in the workshop on the ground, or in the underground wine cellar. The former requires air conditioning and moisturizing equipment to strictly control the temperature and humidity of the workshop. In summer and winter, the cost of temperature and humidity control is high, and in rainy seasons Humidity control is also difficult, and its operating cost is high; if wine is stored in an underground wine cellar, due to the heat preservation and moisture retention of the soil around the wine cellar or the buffering effect on temperature and humidity, the operating cost is lower compared to the workshop wine storage equipment. During the moldy rain season, the humidity in the underground wine cellar is high, and it is difficult to control the humidity. The surface of the walls and barrels is prone to mildew. Once mildew occurs, it is difficult to remove the mold and increase the maintenance cost of the wine cellar.

Bottle storage is also a common process in wine brewing technology. At present, bottle storage is mainly carried out in underground wine cellars, and in the short term, it is also carried out in workshops. All these require temperature control, humidity control, ventilation and other equipment, and strict control of the space for wine storage is required. Humidity and temperature must have good ventilation conditions, and these conditions are easily disturbed by climatic conditions, and it is difficult to achieve very stable conditions, which is not conducive to the maturity, aroma, and quality improvement of wine
