1. 根据葡萄的不同颜色, 葡萄品种可分为白色品种 (白皮白肉), 红色品种 (红皮白肉) 和染色品种 (红皮红肉). 白葡萄酒可以用白色品种酿造, 红酒只能用染色品种酿造, 并且可以用红色品种酿造从白色到深红色的各种不同颜色的葡萄酒.
2. 白葡萄酒是用白葡萄汁发酵而成, red wine is fermented with grape juice (liquid part) and grape skin dregs (solid part). The color of red wine depends on the strength of liquid part to solid part. The stronger the impregnation, the darker the color.
3. The solid part brings not only pigments, but also tannins, which are phenolic substances like pigments. The darker the color of wine, the higher the content of phenolic substances composed of pigments and tannins.
所以, the main difference between red wine and white wine lies in the content and type of phenolic substances between them.
