The primary component of alcohol is ethanol, and it is produced by the saccharification and fermentation of starch-containing plants, followed by distillation. This process is similar to winemaking, but with a lower distillation temperature and more distillation rounds, resulting in a higher alcohol content, higher yield of finished product, and a greater proportion of ether and aldehyde components than in wine. It is not suitable for drinking but can be in contact with the human body. It is a product made from plant raw materials.
