How can a tobacco hotel buy genuine wine?

1, from the implementation standard of liquor.

According to different production processes, liquor can be roughly divided into liquid liquor, solid liquor and solid-liquid liquor. Specifically: ① liquid method GB/T2082 1-2007: blending with edible alcohol. ② Solid-liquid method GB/T20822-2007: It is blended with no more than 30% solid grain-based wine+edible alcohol+essence+water. That is, liquor is partly alcoholic liquor and partly grain liquor. ③ Solid-state method: solid grain wine is produced by solid-state fermentation of distiller's yeast with pure grain as raw material.

2. Look at the wine quality from the main ingredient column.

High-quality liquor is Daqu liquor. China's high-quality liquor is Daqu liquor. The raw materials of koji-making for wine-making are barley, wheat and peas. The wines marked with barley, wheat and peas in the main ingredient column are basically Daqu liquor.

Introduction:

1, empty cup method

Pour the wine into the glass, and then pour the wine out. When you smell the empty glass, it is alcohol blended wine, and when you smell the glass for about ten minutes, it is alcohol blended wine. The brewed wine has grain fragrance, wine fragrance and bad smell. The longer the fragrance is left, the stronger the content of the brewed wine is.

2. Oil melting method

Liquor is rich in esters and aldehydes, which makes a good liquor body have the characteristics of oil melting. If you want to evaluate the quality of a wine, you can drop a drop of cooking oil in the wine. If edible wine can naturally diffuse and sink evenly in wine, it is good wine.

Step 3: Add water.

The wine blended with alcohol does not lose its luster when added with water, and the wine brewed with pure grain loses its luster and turbidity. This is very correct. Brother Puzi personally tested it. This is because some substances in grain wine are insoluble in water and only soluble in wine. After adding water to wine, the degree decreases and the moisture increases, which leads to the precipitation of substances inside.
