A shape. Hold the dry tea in your hand and observe it under bright light. Whether it is a bar or a ball, the color of tea should be fresh, and it is good to have sand, green and frost like frog skin. Pay attention to whether there is a hidden red edge, which is a signal of moderate fermentation; Winter tea is green and spring tea is dark green; If dry tea is black and yellow, it is certainly not good; Those particles are small, shiny as beads, and the leaves are still white, which is a typical appearance of immature buds that are not fully fermented. This kind of tea has a green taste when it is soaked, and it will hurt the stomach if it is soaked a little.
When checking dry tea, pay attention to the feel. Spherical tea is soft and dry. If you shake it in your hand, it should feel weighty. It's too light. It's too light. It's too heavy. It tastes bitter. Tea wrapped in strips, if there is a tingling sensation at the tip of the leaf, is a phenomenon of "water accumulation" caused by the tea being too tender or not green enough, which will be bitter to drink. Hold dry tea in your hand, bury your head in the smell, and take deep breaths for three times. If the aroma continues or even gets stronger, it is good tea. Inferior ones are not fragrant enough. Of course, those with green smell or miscellaneous taste are not selected.
Secondly, open the soup to brew. This is the most important step in tea tasting.
Tea merchants usually grab a handful of tea leaves and fill the teapot when trying tea, which is of course a trick of the merchants. To buy tea and try it, you only need a magnetic cup, 5g tea leaves, and pour 150cc boiling water for 5 minutes. Then take a small spoon to pull out the tea leaves and see how the soup is colored. If it is cloudy, it means that it is not fried enough. Weak, because the picking is tender and the fermentation is insufficient. If fried too much, the leaves will turn yellow and break. A good tea soup is bright and thick, and it looks bright and lovely from light yellow, honey yellow to golden yellow according to the variety and preparation method. Pick up the spoon and smell it. Be careful not to smell like grass. Even if the tea soup is cold, the aroma of good tea still exists. Tea soup is in your mouth, so it is necessary to carefully distinguish whether the "fragrance" mentioned by the boss is an inappropriate grass green taste. The grass green flavor is caused by the lack of rigorous oolong tea technology at present. Once the tea with grass green flavor is added and soaked for a long time, it will inevitably have bitterness and the soup color will become darker.
In short, the principle of purchasing tea is to lose less leaves, flush more water and soak for a long time, so that the advantages and disadvantages of tea can be fully presented at a glance.
