The ways to identify red wine are: look at the bar code, the bottom of the bottle, the grade, the measuring unit, the tightness of the wine seal and the color.

Look at the bar code: there will be an international bar code on the back of imported red wine. The first number of the bar code represents the country, for example, 0 represents the United States, 3 represents France, 7 represents Chile, 8 represents Spain and 9 represents Australia.

Look at the bottom of the bottle: in order to facilitate storage, genuine red wine usually has a deep depression in the bottom of the bottle. If the depression is too shallow, it means that this red wine is probably fake.

Look at the grade: usually, the grades of red wine are A, O and C, and those who reach these three grades are authentic.

Look at the unit of measurement: the capacity of imported red wine on the wine label is 75cl instead of 750ml, and "cl" is deciliter. If it is labeled as "ml" (milliliter), it is counterfeit imported red wine.

Look at the tightness of the wine seal: the wine seal on the wine stopper of genuine red wine can be rotated, because it is actually the cork that seals. And some fake and shoddy brewers, worried that the wine plug would leak if it was not sealed well, sealed the wine.

Observe color: Good quality red wine is generally ruby red, carmine red, vermilion red or purplish red, because it is rich in tannin, anthocyanin and other substances.
