At present, loose wine has become a favorite wine for many people. Its drinking taste is good, especially pure grain wine, which can be widely welcomed by the public. The wholesale of loose wine has a relatively high cost performance. So how to distinguish whether it belongs to pure grain wine when buying wine? The following wholesale staff of bulk Baijiu will analyze for you:
Pour the wine into the glass and then pour it out. The wine brewed has grain flavor and liquor flavor, with high content. The reason for using this identification method is that alcohol itself does not contain aromatic substances, but adds more volatile food flavor.
2. Refrigeration method
Freeze the good wine in the refrigerator for 1-2 hours at minus 1-5. If wine is milky white, it is pure grain wine with cotton-like suspended solids, while Hengjiu is alcoholic wine.
3. Chemical method
Use sodium hydroxide, commonly known as caustic soda. The manufacturer of bulk Baijiu recommends that the Baijiu to be tested be put into a test tube or cup, heated at home at a ratio of 50:1, and then boiled in hot water for a few minutes. If the wine is brewed from grain, the wine in the heated test tube will turn yellow; Because inferior liquor is mixed with alcohol and flavor sweetener, chemical reaction will not occur when it encounters caustic soda, so pure alcohol mixed liquor will not change color after heating; Similarly, if the color of the heated wine is very light, it means that the pure grain wine is not pure, and a small amount of grain wine is added in the mixing process.
4. Hop observation method
Put the wine into the bottle, shake it up and down, and then straighten it. If hops are thick and uniform, they will last for more than 7-8 seconds like pure grain wine. Because in pure grain, the better the wine, the longer the hops wine is stored, the greater the density of hops.
5. Add water
Alcoholic wine will not lose its luster after adding water, while pure grain wine will lose its luster and turbidity. According to the characteristics that fat is slightly soluble in water, pour 2/3 of the wine into the cup, and then add 1/3 of the water. After adding pure water to the blended wine, the color of the wine will remain unchanged, clear and transparent; However, after adding pure water to the original wine, the color becomes white, turbid and opaque.
6. Combustion method
Bulk wine wholesale can also pour an appropriate amount of wine into the cup, light it, and observe the remaining wine after the fire goes out. The grain wine is turbid and the wine is clear. In addition to alcohol, pure grain wine also contains esters insoluble in water, so it is turbid.
