The most effective methods to identify grain-based liquor (authentic fermented liquor) versus artificially blended alcohol are as follows, explained in English:
1. Check the Product Standard Number
Chinese Standard Codes (for reference):GB/T 10781: Indicates traditional solid-state fermented liquor (grain-based).GB/T 20822: Contains both fermented and blended alcohol.GB/T 20821: Fully liquid-state fermentation (lower quality, often blended).Internationally, check labels for terms like "pure grain fermentation" or certifications (e.g., "organic").2. Ingredient List Analysis
Grain-based liquor: Ingredients list only water and grains (e.g., sorghum, rice, wheat).Blended liquor: May include additives like "ethyl alcohol", "flavoring", or "liquid-processed" terms.3. Rubbing Test (Scent Method)
Rub a few drops between your palms until dry:Grain liquor: Releases a fermented, sour-tinged aroma (esters and organic acids).Blended alcohol: ***ells chemical or pungent (volatile additives evaporate quickly).4. Water Test (Cloudiness Check)
Add water to the liquor (1:1 ratio).Grain liquor: Turns cloudy due to precipitation of fatty acid esters (insoluble in water).Blended alcohol: Remains clear (lacks these natural compounds).5. Flame Test
Ignite a ***all amount:Grain liquor: Burns with a steady blue flame and ***ells like fermented grains after extinguishing.Blended alcohol: May produce a sooty flame or chemical odor.6. Long-Term Storage Observation
Grain liquor: Improves in flavor over years (complex aging process).Blended alcohol: Degrades or develops off-flavors due to synthetic additives.Key Notes:
These methods are widely used in China for baijiu (Chinese白酒). Adjustments may apply for international liquors.Lab testing (chromatography) is the only 100% accurate method but requires specialized equipment.Let me know if you need further details! uD83CuDF76
