Among all kinds of Luzhou-flavor liquor, Maotai-flavor liquor is the most storable because its components are relatively stable once formed. But it is not absolute. Sometimes, due to the container, alcohol will be emitted and the taste will become weak.
The newly brewed wine is not necessarily the best, and it needs to be stored for a period of time. During storage, alcohols in wine will react with organic acids to produce esters with special aroma, so some wines will be more fragrant when stored for a long time.
The esterification reaction of wine is quite slow, and high-quality wine generally needs to be stored for three or four years, or even longer. But when the esterification reaction reaches a certain level, it will tend to be balanced and stop. If it continues to be stored, there will be problems such as the decline of alcohol content, the weakening of alcohol taste and the increase of volatile loss.

Selection skills of liquor;
1, the difference between bottle types. Many well-known brands of liquor have unique bottle types. For example, the ivory cylindrical glass bottle that Maotai has been using for many years is smooth and free of impurities; Luzhou Laojiao Tequ uses extraordinary splendour bottles with the words "LU ZHOU LAO JIAO CO.,LTD Winery Patent Bottle" printed on the bottom. Fake wine bottles vary in height and thickness, the outer packaging is outdated, the sealing is not strict or the teeth are uneven.
2. The difference between printing. The label printing of good liquor is very particular: the paper is excellent white, the font specifications are clear, the colors are bright and uniform, the pattern colors are accurate, and the ink lines do not overlap. If there are English or pinyin letters, the sizes and specifications are the same. If you don't have one of the above characteristics, you can conclude that it is fake wine and inferior wine.
3. The difference between bottle caps. At present, most of the 17 famous liquors published and recognized in China use aluminum metal anti-counterfeiting bottle caps, which are characterized by smooth bottle body, uniform shape, convenient opening, neat and clear patterns and characters on the bottle caps and close matching. If it is a counterfeit product, it will often drip out when it is turned upside down, and the cover is not easy to unscrew, and the pattern text is blurred.
4. Different packaging. The paper cover packaging of real wine is beautifully printed, and the edge seams are neat and tight, and there is no phenomenon of uneven tightness and gaps; Some bottles are still wrapped in plastic film, and the packaging is tight and not loose.
5. Difference of turbidity. From the appearance through the glass bottle, liquor should be absolutely clear and transparent without precipitation. The clearer and more transparent the better. You can hold the bottle in your hand, turn it upside down slowly, and observe the bottom of the bottle to see if there is any sinking substance or cloud phenomenon.
According to the convention, if hops are evenly distributed, the gap between the density of hops is obvious, hops slowly disappear, and the wine body is clear and transparent, it is a high-quality wine. If liquor is turbid, with floating impurities, hops turn up densely, are unevenly distributed, and disappear quickly, it may be fake and shoddy liquor.
