1. Observe the Color and Clarity

High-quality bulk liquor should be colorless or slightly yellow, clear, and free of suspended particles or sediment. If the liquid appears cloudy or has impurities, it may be fake or low-quality liquor.

Authentic liquor has a pure and pleasant aroma, such as grain or fermented notes. Fake liquor may ***ell pungent, like alcohol, or have chemical or moldy odors.

3. Test the Texture

4. Observe Wine Bubbles (Foam)

Add a drop of cooking oil to the liquor. In authentic liquor, the oil spreads evenly and sinks gradually. In fake liquor, the oil floats irregularly or fails to disperse.

6. Water Test

Mix liquor with water. Authentic liquor turns cloudy due to precipitation of fatty acid esters (a component of grain liquor). Fake liquor remains clear.

7. Cold Storage Test

Chill the liquor below 1°C. Authentic liquor may show flocculent precipitates (ester condensation), which dissolve upon reheating. Fake liquor remains unchanged.
