What is the English letter meaning of the logo on the bottom of Moutai bottle?

The factory code for producing wine bottles.

The symbols such as MB, HB, CKK and big mouth at the bottom of the bottle are actually the codes of major Maotai bottle manufacturers, and there is no special anti-counterfeiting function. The font of genuine Maotai is full, three-dimensional and clear, and there is generally no problem. However, the identification of Maotai can't completely look at the bottom of the bottle, because it doesn't rule out that some assembly lines have individual defective products, or it may be that some unscrupulous traders have high counterfeiting skills and are not easy to see.

Product technology:

Moutai liquor cellar construction is also quite particular. From the site selection, the direction and space height of the pit area, to the temperature and humidity control, air permeability, the form and capacity of the wine cylinder, and the mud sealing technology of the cylinder mouth, etc., it is very strict. These are the keys to ripen the finished wine and improve the aroma purity. Someone should check the wine cellar every day, open and close the vents, and control the temperature and humidity.

Maotai liquor has a set of production processes different from other liquors, and the production cycle is 7 months. Distilled wine is stored in the warehouse for more than 4 years, then blended with aged wine stored for 20 years, 10 years, 8 years, 5 years, 30 years and 40 years, and finally tested, tasted and bottled for sale.
