How to identify pure grain wine and what is pure grain wine? How can you identify it?

Referring to the national implementation standards behind the wine bottles, pure grain wine that meets the standards of the solid-state fermentation method is the one that meets the standards.

Baijiu (foreign name: chinesebaijiu) is a distilled liquor made by cooking, saccharification, fermentation and distillation with grain as the main raw material, large koji, small koji or bran koji and liquor mother as saccharification starter agent. It is also known as soju, old white dry, burning knives, etc.

The wine is colorless (or yellowish) and transparent, the smell is aromatic and pure, the entrance is sweet and refreshing, the alcohol content is high, and after storage and aging, it has a compound aroma with esters as the main body.

Method 6 of identifying grain wine: Take about 2 taels of liquor, put it in a container that can be heated (it must be non-metallic, glass is the best), add about a small spoon of caustic soda, and put it on the electric stove to heat for 3 minutes. The solution turns yellow for grain wine, and does not change color for blended wine.

Pure grain wine has a strong taste.

Compare the 2 bottles of wine in the quality inspection list.

Pure grain liquor is now called solid-state fermentation, pure grain solid-state fermentation liquor adopts a completely traditional liquor making process, using grain as raw material, crushing and adding koji medicine to ferment naturally for a certain period of time, and the liquor obtained after high-temperature distillation.

The identification method of pure grain wine is as follows.

First, look at the implementation standard number.

China's implementation standards for liquor have mandatory requirements, all liquor needs to be indicated, and GBt10781-2006 solid liquor is pure grain wine, and there are two kinds of alcoholic liquor, one is GBT20821-2007 liquid pure alcoholic liquor, the other is GBT20822-2007 solid-liquid method, which is blended with alcohol and pure grain wine.

2. Use hand rubbing.

Pour a little liquor into the palm of your hand, and then gently rub it with both hands until it is hot, if it is pure grain wine, its wine is mellow and fragrant; The alcoholic wine is pungent and unpleasant, the smell of sake lees is not obvious, and it only takes ten minutes for the wine to dissipate, which is simple and fast to identify.

3. Freezing. Put the liquor in the refrigerator and take it out after being cold for a day, if it is pure grain wine, there will be cotton wool-like suspended matter in it, and the wine body will be milky white and turbid; If it is alcoholic wine, it is still clear and transparent.

Fourth, add water to identify.

Pour the wine into the glass, and then mix with water, if it is pure grain wine, there will be a loss of light, turbidity, this is because some substances in the grain wine are insoluble in water, only soluble in wine, after adding water, the degree decreases, the water increases, these substances will precipitate, resulting in turbidity of the wine; In the case of alcoholic liquor, this phenomenon does not occur.

Fifth, drip judgment.

Pour a glass of liquor, drop a drop of cooking oil into the liquor, if the edible oil naturally diffuses or sinks evenly in the liquor, it means that it is grain wine; If it floats on the surface, is difficult to diffuse, or sinks, it is alcoholic.

Pure grain wine is a type of wine made from grains. The main style characteristics of grain wine depend on the following aspects: one is the koji-making process, the second is the brewing process, the third is the old cellar mud process, and the fourth is the blending process.

The main raw material is the solid-state fermentation process of pure grain. According to the characteristics of "sorghum fragrant, corn sweet, rice net, wheat dwarf, glutinous rice cotton, barley red", sorghum, rice, glutinous rice, corn and wheat are selected as the main brewing raw materials.

The ingredients are sorghum, corn, soybeans and other raw materials, and after solid-state fermentation, it is called solid-state pure grain wine. This wine needs to be mixed with flavors and fragrances before it can be drunk directly. It is generally called pure grain wine, but it is not really pure grain wine.

There is also a process in which wheat and wheat koji are liquid fermented in vats. Distilled spirits are known as true pure grain liquors. This liquor is drinkable after distillation and does not have any flavors and fragrances.

1. Method 1 of identifying grain wine: the real traditional grain brewing wine is fragrant but not choking, slightly bitter but not astringent. The aroma of grain, wine, and lees is obvious, and there is a clear difference between it and the wine blended with alcohol.

The liquor brewed from pure grains smells pure and full, while the liquor blended with alcohol smells very harsh. Pure grain wine has a soft taste, no dry mouth, no choking, no head, and no discomfort after drinking.

2. Method 2 for identifying grain wine: take a drop of liquor and put it in the palm of your hand, and then put your palms together to make the palms of your hands touch and rub it a few times, such as the smell of wine after it is hot, and the retention time is relatively long; On the contrary, alcohol-blended liquor not only smells bad and smells strange, but also has a short retention time and quickly loses its taste. (Alcoholic liquor will be added with flavor additives).

Put the liquor to be tested in a 50:1 caustic soda ratio and put it in a test tube, or you can use a cup that can be heated at home, and then put it in hot water and boil for a few minutes. If it is a liquor made from grains, the liquor in the test tube will turn yellow.

If the color is very light, it means that the pure grain wine is impure and contains alcohol blending ingredients. It does not change color as a pure alcohol blended liquor, because the inferior liquor is blended with alcohol and spice sweeteners, and it will not have a chemical reaction when it encounters caustic soda.

How to tell if wine is grain wine:

1. Pour the wine in your hand into the wine glass, then pour out the wine in the wine glass, wait for about ten minutes and smell the wine in the empty glass with your nose.

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. According to the national implementation standards to judge whether it is grain wine, if it is GB T 10781-2006, it is a wine with pure grain as raw material, and the wine produced by solid state fermentation is pure grain wine; GB T 20822-2007, which is half alcoholic wine and half grain wine; GB T 20821-2007, this is pure alcohol;

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. Drinking a small amount of low-alcohol liquor can dilate small blood vessels, promote blood circulation, delay the deposition of cholesterol and other lipids in the blood vessel wall, which is beneficial to the circulatory system and cardiovascular and cerebrovascular systems.
