How to identify pure grain liquor? How to tell if liquor is pure grain

It can be identified in the following way:

1. The acid of high-quality liquor is more than twice that of ordinary liquid liquor. Esters are also flavor substances in solid-state fermented liquor. The ester content of high-quality liquor is relatively high, more than double that of liquid liquor, so high-quality liquor has a strong aroma.

The aroma of liquid fermented liquor can only be solved by adding synthetic flavor substances. Of course, the fermentation cycle of solid-state fermented wine is long, and the production cost is relatively high.

2. Generally speaking, it is necessary to determine the standard wine sample first, set the standard sample according to the unique style of the famous wine, and then use the standard sample as the benchmark to blend, so that each batch of wine leaving the factory is as close to the standard sample as possible. Secondly, it is necessary to mix the base wine. The requirements of the basic wine are that the aroma is generally the same, the taste is pure and clean, and the color, aroma and taste basically meet the requirements, but there are still some deficiencies, such as short aroma, not long aftertaste, light taste or slightly dry and spicy, etc.

3. The liquor brewing process is complex, the grain distribution is exquisite, and the cycle is long, the relative cost is high, if a distillery wants to increase the output in a short time, it is very difficult, such as some well-known domestic brand liquor, although some after a hundred years of development, its output is only about 30,000 tons per year.

1. Look at the packaging. When buying wine, it is necessary to carefully examine the brand name, color, pattern, label, bottle cap, wine bottle, certificate, gift box, etc. The printing of the label of a good liquor is very particular; The paper is fine and white, the font is standardized and clear, the color is bright and uniform, the pattern is accurate, and the ink lines do not overlap.

The edge seams of the genuine packaging are neat and tight, and there is no uneven tightness and gaps. 2. Look at the color of the wine. The liquor is clear and translucent in the bottle, if it is a transparent glass bottle, facing the sun, you can see the color of the liquor through the bottle, whether there are suspended solids, cloud-like small things or sediments.

Real wine is colorless and transparent, and if there is suspended matter or sediment, it must be fake. 3. Look at the bottle cap. A few days ago, most of the bottle caps of China's famous liquor use aluminum metal anti-caps, which are characterized by smooth caps, uniform shapes, easy to open, neat and clear patterns and words on the caps, and tight counterparts.

If it is a counterfeit product, it often leaks out when it is turned upside down, the cover is not easy to twist, and the pattern and text are blurred. 4. Look at the bubbles. After the bottle is tightly capped, the bottle is turned upside down, if the hops are evenly distributed, the density gap is obvious, and disappears slowly, the wine is clear and high-quality wine; If the hops are densely turned upwards and disappear quickly, and the distribution is uneven, the wine will be cloudy and inferior wine.

5. Look at the manufacturer. The name of the liquor manufacturer is usually printed on the back label of the bottle, which is not large and needs to be carefully checked. If the manufacturer indicates that it is a "branch" or "joint venture", try not to buy it, it is likely to be fake.

Because a real producer generally does not share the enterprise, let alone transfer or lend it. You must know that what the manufacturer sells is the brand and the life, not just the matter of a bottle of wine. 6. Smell the smell.

Take a drop of wine and put it in the palm of your hand, and then rub the palms of your hands a little, and the smell of the wine is fragrant after it is hot, it is a high-quality wine; If the smell is sweet, it is a medium wine; If the smell is bitter, it will be bad wine. 7. Try it with tea. Pour a small amount of wine into the glass, and then drop a few drops of tea, the color of the unadulterated wine will turn pale yellow, and the adulterated wine will turn purple-black.

8. Test with edible oil. Take a drop of edible oil, drop it into the wine, if it can spread regularly and sink evenly, it is a high-quality wine, otherwise, the diffusion is irregular, and the sinking is not obvious for inferior wine.

2. Open the wine bottle and pour a few drops in the palm of your hand, then rub your hands vigorously, and then put your hand under your nose to smell it.

3.

Fourth, we can turn the wine bottle upside down and shake it to observe, if there are many hops in the bottle and disappear slowly, then it is grain wine, and if there are few hops and disappear quickly, it is alcoholic wine.

Pure grain liquor is a unique type of liquor in the world's distilled spirits, which is a beverage fermented, fermented, and distilled from grains or other fruits such as wheat millet, sorghum, corn, sweet potato, and rice bran. Its liquor is colorless and transparent, so it is called liquor.

Pure grain liquor is different from rice wine, beer and fruit wine, in addition to containing a very small amount of sodium, copper, zinc, almost no vitamins, calcium, phosphorus, iron, etc., and only contains water and ethanol (alcohol). Tradition believes that liquor has the function of invigorating blood and pulse, aiding medicinal power, increasing appetite, eliminating fatigue, cultivating sentiment, making people light and refreshing.
