1. Touch. The QR code on the cap of the authentic "Jiang Xiaobai" bottle is UV printed and has a concave and convex feel.

2. Observe. The outer packaging printing of the genuine "Jiang Xiaobai" is more exquisite, with fine ink quality, uniform color and good gloss, while the outer packaging printing of the fake "Jiang Xiaobai" is rough, and the printing ink will be destroyed with a little hard rubbing. ?When buying wine, you must carefully and comprehensively examine the wine’s brand name, color, pattern, label, bottle cap, bottle, certificate, gift box, etc.

3. Scan. The QR code on the bottle cap of authentic "Jiangxiaobai" sorghum wine is one code per bottle, which is consistent with the information marked on the bottle.

4. Look. The normal color of liquor should be a colorless and transparent liquid without suspended matter or sediment. Pour the white wine into the cup, and there should be no ring-shaped insoluble matter on the wall of the cup. Turn the wine bottle upside down and observe the wine body in the light. There should be no suspended solids, turbidity or sedimentation. In winter, if there is precipitation in the liquor, you can use a water bath to heat it to 30-40°C. If the precipitation disappears, it is normal.

5. Smell. When conducting sensory identification of the aroma of liquor, it is best to use a glass with a large belly and a small mouth. Pour the liquor into the glass, shake it slightly, and immediately use your nose to smell the aroma carefully near the mouth of the glass. Or pour a few drops of wine on your palms, rub it a few times, and then smell your palms to identify whether the intensity and type of aroma are normal.

6. Product. Drink a small amount of wine and spread it on your tongue to judge whether the taste is thick, soft, mellow, rough, sour, sweet, sweet and spicy, and whether there is any aftertaste. The real Jiang Xiaobai has a smooth mouthfeel and clean taste. I don’t have dry mouth or headache after drinking it, and I don’t feel uncomfortable or tired the next day.
