沸水泡茶 不少人喜欢用刚烧开的水泡茶叶,这是不科学的。因为茶叶中含有一种苦涩味的物质——鞣酸,在高温作用下,鞣酸会过多地溶解出来,增加茶水的苦涩味,而且还会使茶叶中不耐高温的维生素大量破坏。泡茶叶的水温宜按茶叶的质量来定,一般茶叶可用95℃的开水冲泡,高级茶叶和细嫩茗茶则以80℃左右为好。 Many people like to use boiling water blisters boiled tea leaves, it is unscientific. Because tea contains a bitter taste of the material - tannic acid, under the action of high temperatures, tannic acid will dissolve too much, increase the bitter taste of tea, but also make a lot of tea in the heat-damaging vitamin destruction. Tea water temperature should be based on the quality of tea to be set, the general tea available 95 ℃ boiling water, high tea and delicate tea is about 80 ℃ as well.
