Alcohol and alcohol testing

This standard specifies the method for determining the alcohol content in alcohol, distilled liquor, fermented liquor, and prepared liquor. This standard is applicable to the determination of alcohol content in alcohol, distilled liquor, fermented liquor, and prepared liquor. Among them: the first method is applicable to distilled spirits, fermented spirits, and blended spirits, the second method is applicable to alcohol and distilled spirits, fermented spirits, and blended spirits (excluding beer), the third method is applicable to wine, fruit wine, and beer, and the fourth method is applicable to digital densitometer for beer, brandy, whiskey, and vodka. The first method, density bottle method 2, uses distillation to remove non volatile substances from the sample. The density of the sample (alcohol aqueous solution) at 20 ℃ is measured using the density bottle method. Refer to Appendix A - to obtain the volume fraction of ethanol content at 20 ℃, which is the alcohol content. 3 Instruments and equipment 3.1 Analytical balance: sensitivity 0.000 1 g. 3.2 Full glass still: 500 mL. 3.3 Constant temperature water bath; Temperature control accuracy: 0.1 ℃. 3.4 Attached thermometer density bottle: 25 mL or 50 mL. 4 Analysis steps 4.1 Sample preparation 4.1.1 Distilled liquor, fermented liquor, and prepared liquor samples (excluding beer and sparkling wine) are prepared using a clean and dry 100 ml volumetric flask. Accurately measure 100 ml of the sample (liquid temperature 20 ℃) and place it in a 500 ml volumetric flask. Rinse the volumetric flask three times with 50 ml of water. The washing solution is merged into a 500 ml volumetric flask. Add several zeolites (or glass beads), connect a serpentine condenser tube, and use the original volumetric flask used for sampling as a receiver (with an ice bath), Turn on the cooling water (the temperature of the cooling water should be lower than 15 ℃), slowly heat and distill, and collect the distillate. When approaching the mark, remove the volumetric flask, cap it, and keep it warm in a 20 ℃ water bath for 30 minutes. Then add water to the mark, mix well, and set aside
