Hello, my friends, as usual when we drink tea, we would have such mouth-feel of thirst quenching, do you know why do you have such mouth feeling? Because of organic acids, like malic acid, citric acid, and so on, which are also very important in wine(Well you may not feel its sourness when drinking tea actually, that’s because the other main ingredients like tea polyphonel, caffine, polysaccharides gives tea the strong tastes, which hide the sourness).
当我们喝茶时，讨论比较多的如回甘、生津等。生津，顾名思义从字面意思上说就是从口腔中分泌出唾液。那你知道生津是如何产生的吗？ 因为有机酸（或许你会说，不会吧，那我怎么没有感觉到酸度。 那时因为有机酸的含量比较低，因此被茶多酚、咖啡碱等主要的呈味物质所掩盖了），比如苹果酸、柠檬酸等，这些有机酸也是葡萄酒中的主要酸味物质。
Tea can quench thirst because those acids can promote your tongue to produce more saliva, balance its overall taste. Beside, they are also able to protect wine or tea from turning bad. If you recall you tea - drinking experience, almost all the teas have such mouth feeling mainly on both cheeks（as usual, we keep the tea infusion in mouth a few seconds, use our tongue to feel its tastes, and then swallow it by leting the tea flow throw the two cheeks）. For better tea, your whole tongue, even your teeth root would have such feeling.
Of course, thirst-quenching may vary due to different tea species, different types of tea and processings. For pu-erh tea, the storage matters a lot. For some aging pu-erh being well processed and stored, it has very strong thirst quenching, which is so pleasant.
Well, drinking tea is very personal and somehow professional. So, next time, when you try a cup of tea, try to experience it by yourself. Subscribe to us, to learn tea more. See you next time.
