1, observe the bottle.

See if the label on the bottle is clearly printed. If it is ambiguous, it is likely to be a counterfeit product. Secondly, look at whether the sealing cover of the wine bottle is abnormal, whether there are signs of being opened or damaged. If the cork of the unopened wine is raised or there is mucus in the bottle mouth, it means that there is something wrong with the quality of the wine. In addition, if there is an icon with a female head on the lead seal of the wine bottle, it proves that this is the authentic original wine after paying taxes in France.

Step 2 observe the wine body

Observe whether the color of the wine is normal. Usually, the color of wine is clear and natural, such as ruby red, light gold or peach red. After the wine body goes bad, it will have a turbid feeling. If the color is unnatural, it may be mixed. In addition, see if there are any unknown suspended substances in the wine. If there is only a little precipitation at the bottom of the bottle, then this is a normal crystal.

Step 3 look at the sign of the wine stopper

Open the bottle and see if the words on the cork are the same as those on the bottle label. In France, wine bottles and wine stoppers are special. Nowadays, more and more countries gradually replace cork stoppers with rubber wine stoppers for environmental protection, and there are also screw caps designed, which have nothing to do with the quality of red wine itself.

Step 4 smell it

Usually, before tasting red wine, everyone will smell it first. The same is true for buying red wine. You should smell it. Usually when you open a bottle of red wine, the aroma of the wine will come to your face, sometimes it will be fruity or floral. If you smell the choking smell of nail polish or acetic acid, it means the wine has gone bad.

5. Observe a glass of red wine hanging.

Pour the red wine into the glass and shake it gently to see if there is a hanging glass. If the wine can't be hung, it may be blended. Normal red wine will be hung on the glass wall in a uniform circle, which is very detailed.

6. wine tasting

How do you know the quality of wine without tasting it yourself? After drinking the first sip of wine, when the wine passes through the throat, normal red wine gives people a smooth feeling. If there is a strong sense of stimulation, or the smell left in the mouth has a chemical smell or bad smell, it means that the wine is inferior.
