1, the smell of dry tea is strong and tangy: the smell of real pure tea dry tea is relatively light, and it is only slightly fragrant if you smell it close. If your tea has a strong fragrance as soon as you buy it and open it, it is likely that it has added essence.

2. Water with low temperature can also brew strong tea fragrance: the essence can dissolve quickly at 80℃, while the real pure Chaze generally needs to brew its natural tea fragrance and taste with water above 95℃ to release it. The aroma of tea containing essence is not only pungent, but also the tea soup is somewhat turbid.

3. Observe the tea stains of the soaked tea leaves overnight: When we finish drinking the tea, don't throw the tea leaves away in a hurry. We can leave the soaked tea leaves overnight and observe the color of the tea stains in the teacup. If you see that the color of tea stains is light yellow, dark yellow, orange and other yellow-orange series, it means that tea does not contain additives; On the contrary, if the tea stains in the teacup are observed to be light green or dark green or dark green, it means that the tea leaves are likely to contain essence or other additives.

4. Use a paper towel to distinguish whether it contains essence: With the help of the adsorption ability of paper, you can take out a paper towel and put it in dry tea for one hour. If the paper smells like chemical essence, it is very likely that essence has been added to the tea. Another method is to make tea with a large cup, cover the mouth of the cup with a paper towel, and take it away for 1 minute to cool. If tea contains essence, the pungent smell absorbed by paper towels is not easy to disperse.

5. When brewing, the fragrance will soon drift away, which is not lasting: the tea with essence will be soaked out quickly in the process of brewing because it is a subsequent chemical component. Generally, the first three bubbles have a strong aroma, but then they will go straight down in vain, and the aroma will suddenly weaken. Generally, the aroma of normal tea can last for 5~8 bubbles, and then the aroma of tea begins to weaken.
