What is the reason for adding sugar to homemade wine?
Many people are afraid that sugared wine will make them fat, so they don't put sugar at all when making wine. Results A few days later, they found that the grapes had completely rotted and deteriorated, and white sugar would directly affect the alcohol content of the wine. If no sugar is added at all, the alcohol content of the wine is only 10, and the brewed wine has no taste of boiled water. At this time, we must add sugar to the wine. White sugar will react with various enzymes in the container and eventually produce glucose, which will ferment to produce alcohol and carbon dioxide. The more sugar there is, the more alcohol will be produced, and the higher the alcohol content will naturally be.
