Embodiment 1

[0023] Store liquor in 225L new American oak barrels, cover the oak barrel lid (not completely sealed) for the first 2 days, then completely seal the barrel lid of the oak barrel, and place it in a cool and dry room with a temperature of 25°C and a humidity of 70%. , stored for a total of 6 months, then poured into old oak barrels and stored in the same environment for 1 year. Then take it out and enter the post-processing process, filling and packaging into finished wine. After being stored in old oak barrels for 1 year, sensory evaluation and determination of loss rate and aroma components were carried out, as shown in Table 1, Table 2, and Table 3.

Abstract

The invention discloses a barrel replacing method used in a period that oak barrels stores Baijiu, and belongs to the technical field of Baijiu storage and barrel replacement. The method comprises the following steps: (1) Baijiu different in alcohol content is put into new oak barrels with the volumes being 200-500L, the oak barrels are placed in a cool and dry room, the indoor temperature is kept at 20-30 DEG C, the humidity is kept at 50-70%, and the Baijiu is stored for 3-6 months, wherein one side of a barrel cover of each oak barrel is raised for 1-3 cm two days before storage to allow gas to overflow from the space between the barrel cover and the inner wall of a barrel body, and the barrel cover and the barrel body are completely sealed from the third day; (2) after the Baijiu is stored in the new barrels for 3-6 months, the Baijiu in the new oak barrels is poured into old oak barrels or pottery jars for barrel replacement, and are stored for 1 year under the same environmental conditions, so that the finished Baijiu products have special tastes and special colors. The method develop a new style, not only the new oak barrels but also the old oak barrels and the pottery jars are utilized for storing and alcoholizing the Baijiu, fragrance of the oak barrels and aroma- and flavor-producing substances in the Baijiu are organically combined, and the qualities of the Baijiu are further improved.

Description

technical field [0001] The invention relates to a barrel inversion method during the storage of liquor in oak barrels, and belongs to the technical field of liquor storage and barrel inversion. Background technique [0002] Traditionally, liquor is generally stored in pottery jars or food-grade stainless steel tanks to allow it to age naturally, but it cannot increase the aroma and taste substances in liquor. The pottery altar has the characteristics of good air permeability, various metal oxides contained in the wine are dissolved in the wine during the storage process, which can promote the aging of the liquor, and the production cost is low. However, the pottery altar is made of microporous mesh Structural composition, if the quality of the glaze coating is not good, there will be leakage of wine, the annual loss rate is about 2%, and the volume of the pottery container is small, and the storage of wine occupies a large area of ​​the warehouse; the volume of the stainless...
