问题 问答题 简答题

现代人对泡茶用水的选择?

答案

参考答案:

①自来水:最常见的生活饮用水,是属于加工处理后的天然水,为暂时硬水,因其含有较多的氯,饮用前需置清洁容器中1~2天,让氯气挥发,然后煮开用于泡茶,水质还是可以达到要求的。

②纯净水:蒸馏水、太空水的合称,是一种安全无害的软水,其纯度高,不含任何添加物,可直接饮用。用纯净水泡茶,其效果较好。

③矿泉水:饮用天然矿泉水是含有一定量的矿物盐、微量元素或二氧化碳气体的水,与纯净水相比,矿泉水含有丰富的锂、锶、锌、碘和偏硅酸等多种微量元素,饮用矿泉水有助于调节肌体的酸碱平衡。若矿泉水含有较多的钙、镁、钠等金属离子,则是永久性硬水,即使营养丰富,用于泡茶效果也不佳。

④活性水:活性水包括磁化水、矿化水、离子水、生态水等,是自来水经加工处理而成,具有特定的活性功能和营养性功能。

⑤净化水:净化水是通过净化器对自来水进行二次终端过滤处理制得,使自来水的水质有所提高。用净化水泡茶,其茶汤品质相当不错。

⑥天然水:天然水包括江、河、湖、泉、井及雨水。用这些天然水泡茶应注意水源、环境、气候等因素。在天然水中,泉水是最理想的泡茶用水,杂质少,透明度高,污染少,虽属暂时硬水,加热后,呈酸性碳酸盐状态的矿物质被分解,口感特别微妙,泉水泡茶,甘冽清香具备
