Definition of red wine: select wine grapes with red skin and white meat or red skin and red meat, ferment with mixed skin juice, and then separate and age. The color of this wine should be natural ruby red, purple red or pomegranate red. Red that loses its natural feeling does not meet the color requirements of red wine.
Definition of white wine: wine made by selecting white grapes or wine grapes with light red peel, separating peel and juice, and fermenting juice. The color of this wine should be approximately colorless, light yellow with green or light yellow or straw yellow, which is too dark to meet the color requirements of liquor.
Definition of pink wine: This wine is between red wine and white wine. Wine grapes with red skin and white meat were selected for short-term mixed fermentation of skin juice. After reaching the color requirement, the peel and residue are separated and continue to ferment and mature into pink wine. The color of this wine is pink or rose or light red.
