In recent years, there have been companies selling corn wine on the market. The two types of corn wine are yellow and dark purple. According to the principle of distillation, alcohol droplets are formed by evaporation and condensation. Regardless of whether the wine is from rice, corn, cassava or paddy, it has a slightly opaque white color. White is the color of the standard wine, and wines with a yellow or purple color can be identified as a wine with added colorants or chemicals.
