All Made from Grains, Why is Pure Grain Liquor So Coveted?
All are made by fermentation of grains, and then distilled by brewing machines, which is why pure grain liquor is highly coveted, while edible alcohol is rejected. What is the real truth behind this?
1. Alcoholic liquor is made from edible alcohol, added with water and fragrance, to become liquor.
Edible alcohol is a product obtained by fermentation of sugar beets, potatoes, grains and enzymatic hydrolysis in fermentation tanks, followed by filtration and distillation. It is usually an ethanol-water solution, or a mixture of water and ethanol.
Edible Alcohol
Corn is the best raw material for producing edible alcohol, but it is rarely seen in the market due to its high cost. The rare corn alcohol on the market is made from corn stalks instead of good corn.
Because edible alcohol does not have the flavor and taste of grain liquor, it needs to be added with water and fragrance in addition to being mixed.
2. Grain liquor refers to liquor made from grains such as sorghum, corn, rice, glutinous rice, barley, wheat, millet, quinoa, and other grains, which are saccharified, fermented, and then distilled by brewing machines.
Common brewing ingredients for grain liquor
The commonly used brewing processes include solid-state brewing, semi-solid-state brewing and liquid-state brewing.
Solid-state brewing is suitable for shelled grains such as sorghum, corn, wheat, barley, quinoa, buckwheat……
Traditional sorghum solid-state fermentation
Semi-solid-state brewing is suitable for rice such as rice, glutinous rice, millet, sorghum rice……
Liquid-state brewing is suitable for rice, potatoes and some specialty brewing materials, and most fruit white liquors also use liquid-state brewing.
Grain liquor, in addition to acetic acid and water, also contains 1-2% trace elements, which are generally divided into four categories: alcohol, aldehyde, acid and ester.
This 1-2% trace element determines the flavor of 100% grain liquor, and also determines the aroma type of grain liquor, such as
The typical aroma of concentrated aroma liquor is ethyl acetate, and this component has a high fragrance content and prominent aroma;
The main aroma of clear aroma liquor is ethyl acetate and lactic acid ethyl ester, which combine to form the main aroma of the liquor, characterized by being clear, refreshing, mellow and clean;
The aroma composition of rice aroma liquor is lactic acid ethyl ester content is greater than ethyl acetate, and the content of high-boiling alcohol is also abundant, forming its main aroma.

After saying so much, do you now know the difference between alcoholic liquor and pure grain liquor?
