How does Changyu wine distinguish between true and false?

How does Changyu wine distinguish between true and false? Let's take a look at Bian Xiao's sharing today.

1, look at the trademark

The trademark of authentic Changyu wine is very clear, with a Y symbol and a small pentagram on it.

2. Look at this wine stopper

The cork of authentic Changyu wine is usually a cork, and the words Changyu wine are also marked on the cork, while some "three noes" counterfeit products use plastic corks.

Step 3 look at the color of the wine

Changyu wine is deep ruby red. Through the light, you can see that the wine is clear but not turbid, while fake wine is usually dark and turbid.

4. Look at the capacity

Authentic Changyu liquor is filled mechanically with a total capacity of 750ml, while counterfeit liquor is easily filled manually.

Step 5 look at the date

Judging from the date of outer packaging, the date of real Changyu wine was printed, while most fake Changyu wines were printed.

6, look at the anti-counterfeiting logo

Many brands of wine bottles will use rice moisture-sensitive anti-counterfeiting technology. You can display the anti-counterfeiting mark by wiping it with water.

Expanding knowledge: how to preserve Changyu wine

1, suitable temperature range:

The optimum temperature for wine storage is about 15℃, but it is difficult to keep the temperature of 15℃ all the year round in China. But a little higher temperature has little effect on wine, and the overall temperature can be controlled below 20℃.

2. Avoid light:

Red wine should be kept away from light, especially white wine and peach wine, which are generally kept in transparent bottles. Long-term illumination may cause the reduction reaction and "photooxidation" of wine.

3, keep the environment clean and ventilated:

The environmental smell of Tibetan wine will also affect the taste of wine. Wine can't be completely sealed before opening, and the air exchange function of cork is likely to introduce the smell in the air into the bottle. Therefore, it is very important to keep the air circulation and the environment clean.

4. Avoid shaking or shaking:

Wine bottles need quiet "sleep" during storage, so try to avoid shaking during storage. This phenomenon is particularly obvious in the process of wine transportation. After a long period of transportation, wine will appear "light bottle", the aroma will be blocked and the taste will be dull. It needs to be quiet for a while to regain its vitality.

5, keep the level:

Most wines still smell of cork. In order to prevent the cork from drying and shrinking, the cork is still placed horizontally to keep it moist and swollen to avoid oxidation.

6. Keep the humidity as high as possible:

Storage humidity should be above 70%, mainly to prevent cork from drying out. However, when people store wine at home, it is difficult to control the air humidity. At the same time, keep the bottle flat, which can basically meet the humidity requirements of cork, so don't worry too much.
