The blue label implementation standard 1781.1 is excellent, which means solid-state fermentation of pure grain wine. Round bottle red label, implementation standard 2822, solid-liquid liquor, commonly known as alcohol blended wine, in which the content of pure grain wine is less than 3%, and the rest is edible alcohol, water and spices.

How to tell the authenticity of Mianzhu Daqu:

1

Look at the outer packaging. Generally, according to the requirements of the National Bureau of Quality, there will be a bar code on the outer packaging of wine, which is also the anti-counterfeiting code. Any wine company in China will have an identification website. Just go to the website of the wine and enter the bar code, and you can find out whether it is true or not.

2

Look at the reflectivity of the trademark. Generally, wine will have its own trademark. Nowadays, technology makes the trademark very well, and it has certain transparency or color change. Under normal circumstances, after buying wine, it is recommended to look at the wine online first, how to identify these trademarks, and what are their characteristics, and then look at them when buying. Usually, normal trademarks are colorless, clean and smooth.

3

Generally, liquor has its own special fragrance. For wine, after we buy it, we open it face to face and smell it to see if it is natural and mellow. Or drop a little into your palm, and then rub it to let its fragrance naturally emanate. After smelling the fragrance, look at the volatility again. If the volatility is slow and there are water stains on your hands, it proves that it is wine with water, which is usually inferior or fake.

4

Take a sip. Ordinary white wine, because it is made of pure grain, will not be spicy when it is drunk, and the imported cotton will have the feeling that the fragrance will flow to the lips and teeth. Inferior wine or fake wine, under normal circumstances, when drunk, will be very spicy, and easy to get on the head, causing headaches and discomfort.

5

wine is judged by its alcohol content. If it contains a large amount of water, it will spread quickly to oil. This general chemistry student knows. So, you can bring the wine, then pour a glass, and add a drop of oil to the glass to see the oil diffusion. If it spreads quickly and unevenly, and the oil goes into the wine, it proves that it is watered wine, bad wine or fake wine.
