The labels of liquor bottles produced by regular wineries are all marked with the description of "liquor implementation standards", which is clear at a glance. The label of pure grain liquor is GB\T 1078 1-2006, the label of pure alcohol blended liquor is GB\T2082 1-2007, and there is a semi-pure grain semi-blended liquor which is always between pure grain liquor and blended liquor with the label of GB\T20822-2007. For example, the following bottle of white wine, marked GB\T20822, must be a bottle of semi-pure grain and semi-blended white wine.

In addition, there are some special cases of liquor. The standard shown above is not necessarily the national standard above, but the enterprise standard. For such liquor, don't look at the label, just look at the ingredient list inside. The ingredients list shows raw materials, which are pure grain and wine. Besides water, the ingredients also include various grains. As long as there is something else, you can definitely blend wine.

Pure grain wine, as long as you shake the glass and hang it on the glass wall, it is basically pure grain wine. In addition, it depends on whether it can be burned. As long as it can burn, it is 100% pure grain wine, because even the blended wine is of good quality, it cannot be ignited. If it can be ignited, judging from the color of the flame, the bluer the color, the higher the purity of the wine. In addition, good pure grain wine, don't brush the cup after drinking, smell it again the next day, and the strong wine will not go away.
