葡萄酒的pH值与二氧化硫的关系

Relations of pH Value and Sulfur Dioxide in Wine

控制葡萄酒陈酿时原酒品质,其主要影响因素为原酒的pH值和二氧化硫的用量,根据原酒的不同pH值,对游离二氧化硫的用量加以调节,达到二氧化硫防腐、抗氧化的作用。

The main factors affecting the quality of crude wine during wine-making are pH value of crude wine and using quantity of sulfur dioxide.The using quantity of free sulfur dioxide was regulated in line with different pH value of crude wine so that the aim of using sulfur dioxide against erosion and oxidation could be achieved.(Tran.by YUE Yang)
