1. Observe the rubber cap: The rubber cap of genuine Maotai is disposable and cannot be restored. When observing Moutai in different light, the logo of Maotai and the words "Maotai is a national wine" should be clearly visible. When backlit, the logo and text will be dimmed. There is a "red star" sign on the anti-counterfeiting rubber cap of Maotai. If observed with a recognizer, the background color of roof caving will turn bright yellow and the star sign will turn gray. There will be a black floating point on the rubber cap, which will drift with the rotation of the cap.

2. Check ribbons: The two ribbons of real Moutai should be the same length, while the ribbons of fake Moutai are different in length, one is long and the other is short. In the natural vertical state, the two streamers of Moutai should be facing the word "Mao" on the label, and the bottom of the streamer should not exceed the lower part of the word "Mao", about at the hook below the word "Mao". There should be white words "China Kweichow Moutai" on the ribbon of genuine Maotai, and there will be a number from 0 to dozens on the inner ribbon, which is located near the second paragraph of the bottle.
