1. Is the color of the wine clear?

For high-quality liquor, the color of the wine will be clear and translucent. Like the national flower Porcelain Qingyun 20 that we usually drink, when poured into a wine glass, it is crystal clear and you can tell it is a good wine at a glance. If it cannot be opened, you can use the comparison method. You can turn two bottles of the same brand of wine upside down at the same time. The bottle of wine with the bubbles disappearing slowly is of good quality. The bubbles disappear slowly, indicating that the wine has a high concentration and a long storage time. Drink The taste is mellow.

2. Is there any sedimentation at the bottom of the bottle?

Under normal circumstances, liquor is colorless and transparent. If there is sedimentation, there must be something wrong with the quality of the wine. When observing wine, pay attention to facing the light or sunlight, slowly turn the bottle upside down, and observe the bottom of the bottle. If there are sinking objects or cloud-like phenomena, it means there are many impurities in the wine; if the wine does not lose light, is not turbid, and has no suspended solids after the bottle is turned upside down, it means the wine is of good quality. In terms of color, liquor should generally be colorless and transparent. There are exceptions, such as Kweichow's Moutai. The liquor is slightly yellow, but very light, which is normal.

3. Is the wine bottle defective?

Inferior liquor is full of defects, both in terms of quality and packaging. Before liquor leaves the factory, many wineries use aluminum spiral "anti-theft caps" to seal the bottles. Such bottle caps are safer. Then check the trademark logo on the wine bottle. Generally, the trademark logo of real wine is more beautifully printed, the color is very bright, and has a certain luster. When choosing liquor, you should also pay attention to the bottle packaging to see if the bottle cap is tightly sealed and whether the bottle has cracks or blisters. If there are any of the above defects, the wine will easily leak, run out and lose volume.

4. Determine the alcohol content

To judge the alcohol content, most consumers directly look at the label on the bottle. In fact, the alcohol content of liquor can also be determined by observation. The degree of liquor can be determined by shaking it. After shaking the bottle, if there are hops the size of millet grains to sorghum rice grains, the heaping time is about 15 seconds, then the alcohol content is about 53-55 degrees; if the hops are the size of sorghum rice grains, the heaping time is 7 seconds If the hops are about the size of sorghum grains to corn grains, and the heaping time is about 3 seconds, then the alcohol content can reach 65 degrees.
