Eight Unpleasant Smells In Tea, If You Smell One, Throw It Away!

Update:14 Jan 2022

  When these flavors appear in tea leaves, good tea becomes inferior tea, so throw it away!

  1. Dusty, earthy

  It is more common in ripe Pu, Xiaoqing mandarin, and dark tea. The earthy taste here is a bit fishy and a little sour, like the rotten taste in the orchard, and the feeling of suddenly chewing mud in the mouth. If these two flavors are present in the tea, the tea cannot be drunk.

  Eight unpleasant smells in tea, if you smell one, throw it away!

  Causes: During the stacking fermentation process, the over-fermentation of cooked tea and the substandard craftsmanship may cause earthy taste; the storage environment conditions are very general, and the excessive humidity will also cause earthy taste in the tea.

  2. Oil smell

  The smell of oil may appear in all kinds of teas. This unpleasant "volatile organic solvent" smell can occur when tea leaves are contaminated during processing, transportation, or storage, with a dangerous smell reminiscent of a car oil spill.

  Such tea cannot be drunk, because the metal ions in tea may seriously exceed the standard. The price of such tea is not high in the market, because the cost of machine production is not as high as the fraction of hand-made.

  Cause: Unclean machine contamination during tea making, or problems during packaging and storage.

  3. Spicy

  It is more common in black tea and white tea. This kind of taste is usually a bit "domineering", of course not the domineering of Lao Banzhang. I opened a tea and took two sips, and I felt the urge to sneeze. If you drink two sips of this tea, it is normal to be spicy like when you eat hot pot. If it is spicy, then the tea is useless.

  Cause: During the production process of black tea, the fermentation is not in place, and it is dried at high temperature; the white tea is not withered in place, with green gas, which absorbs some peculiar smells, and is affected by water vapor during storage, which will cause the tea to produce a stimulating and spicy taste.

  4. The smell of rotten eggs

  Cooked Pu and China green tea are more common. When you are happy to brew a cup of tea leaves that are beautifully packaged and dry tea evenly, after brewing in boiling water, the stench of rotten eggs and the stench of rotten eggs is so sad. We must note that before buying tea, it is best to brew it with boiling water and smell the bottom of the leaves. Some poor-quality teas will smell rotten eggs from the bottom of the leaves after washing the tea.

  Cause: This kind of tea with a rotten egg smell is rare, which is due to improper processing and storage, which leads to a chemical reaction in the tea itself.

  5. Burnt smell

  Small green mandarin oranges, oolong tea, and dark tea are more common. At the moment when the tea soup is entered, the smell of fireworks and fishy stench comes through the nose, and you will feel that your mouth is full of earthy smell and burnt vegetable leaves.

  Cause: The cause of the coke odor is usually the carbonization of the bottom of the leaves. There are three possibilities for carbonization of the leaf bottom: the temperature is too high when the tea leaves are green; the temperature is too high and too long when drying; improper storage may also cause the smell of charred adsorption.

  6. Sour and sour taste

  White tea and black tea are more common. The sour taste is a serious illness of qualitative change! This kind of tea with a sour and rancid smell smells sour and irritating, accompanied by other unpleasant feelings. Moreover, tea with a sour and rancid taste has a sour and rancid taste in both hot and cold smells. This seriously deteriorated tea must be thrown away.

  Of course, we will drink tea with a "sour" taste. Some of the sour tastes make people feel a touch of "fruit and sour fragrance", but some unpleasant "sour and sour tastes" make people inexplicably resist.

  Cause: During the withering process of tea leaves, the fresh leaves are piled up for too long or the fresh leaves are piled too thickly, which causes the raw materials to deteriorate due to heat; or the finished tea is damp. Generally speaking, improper fermentation of black tea; or white tea in a humid environment during storage, is prone to sour and rancid tastes.

  7. Rotten smell

  It is more common in dark tea and small green oranges. According to the recollection of a senior tea ghost, I once drank an indescribable black tea that tasted like rotting compost. As for this disgusting smell, it is no wonder that some people say that low-quality small green mandarin is also prone to rotten taste, it feels like eating a rotten pulp...

  Cause: This odor is also caused by a problem with the flora produced by the tea leaves during fermentation, resulting in poor fermentation of the tea leaves when they are stored. If this kind of taste appears in the small green mandarin orange, it may also be because the tea leaves are not dried in time; the drying is not in place, resulting in the outer peel being dry, while the inner tea leaves are not completely dry.

  8. Musty smell

  It is more common in dark tea and cooked tea. How can something go moldy in the entrance? The smell of musty is reminiscent of clothes hanging in a damp basement, or a damp old house that has not been lived in for a long time, often with an unpleasant musty smell. If the tea has a musty bad smell, it is pungent and unpleasant, and it is not recommended to drink it.

  Cause: Improper production of tea (such as excessive fermentation, high humidity); or inadequate storage (such as long-term storage in an environment with high temperature and humidity), resulting in the tea being damp and moldy from the inside to the outside, resulting in a bad smell.

  There are more peculiar smells in tea leaves, but the fragrance of good tea is pure and free of peculiar smells. If there is a pungent smell in the tea leaves, you can no longer drink them.
