What is the reason why black tea tastes sour? When many people drink black tea, they always have such a feeling? Why does black tea have a burning smell? It turns out that it is because of the process defects and storage problems, and the burning smell is also because of the high temperature in the frying process.
The reason why black tea tastes sour
1. Acid formation due to process problems
Black tea is sour, the most common reason is in the production process. As we all know, black tea belongs to fully fermented tea, and fermentation exists in every process of withering, rolling, fermentation and drying. If the technical factors such as temperature, humidity and ventilation are not properly controlled, it is likely that 'improper fermentation' will occur, and the sour taste will occur easily.
2. Acid caused by improper storage
During the storage of black tea, the absorbed water will be fermented again, producing peculiar smell components (acetic acid, propionic acid, etc.), thus producing sour taste. Therefore, we often hear tea friends say that the reason for storage is that the black tea which has been stored for several years can drink obvious sour taste when drinking again.
3. Acid caused by brewing method
Each black tea has its own characteristics. Some black tea can be brewed with boiling water. And if some black tea is tender, and the black tea is fully fermented, many of the contained substances have been forced at the door, and also rushed with boiling water, the contained substances will be completely brewed, which also includes' acid ', so it is inevitable that we will taste the sour taste.
4. Raw material problems lead to acid
This is the most unclear, but also we have to discuss. Some black tea has a very good production process, proper storage, and almost perfect brewing method, but there is an inevitable sour taste. This can only be attributed to the raw materials. There are many factors that affect the quality of raw materials, such as soil, climate, and picking in rainy days.
Why does it smell burnt
This is actually caused by the defect of black tea technology. The common defects of black tea are not only acid, but also burnt, mixed and green. The scorching smell is that during the baking process, it has been baked. There are many sources of mixed flavor. For example, in the process of withering, the tea is piled together, too thick and not spread out in time, which is easy to produce sour taste. There is also knead after not drying in time, also not spread out in time will produce miscellaneous flavor.
To teach you a simple way to distinguish, is to smell the bottom of the leaves. Acid taste can be judged more clearly by drinking, but burnt taste, miscellaneous taste and green taste can be distinguished by smelling the bottom of leaves without drinking. A kind of black tea with good technology, the leaf bottom should smell comfortable, without any miscellaneous taste.
