It depends on what kind of tea you are tasting, because each tea has its own characteristics:

The quality of tea can be determined by its color, aroma, and taste. Evaluate from four aspects: , shape and form. These four aspects are used to evaluate the quality of tea, usually by looking, smelling, touching and tasting. That is, look at the appearance, color, smell the aroma, feel the rope, and open the soup to taste.

Look at the color----different tea types have different color characteristics. Green tea is gray and dark brown in color and must be of poor quality. The vapor color of green tea should be light green or yellow-green, clear and bright; if it is dark yellow or turbid, it is definitely not good tea. The black tea should be dark and oily, and the soup color should be red and bright; if the soup color is dark and turbid, it must be inferior black tea. Oolong tea is preferably green-brown in color and smooth in color.

Look at the appearance----The quality of the tea can be judged from the appearance of the tea leaves. For example, good Longjing tea has a smooth, flat, straight appearance, shaped like a bowl nail; good pearl tea has round, tight and uniform particles; good Gongfu black tea has tight and neat strips, and the particles of broken black tea are neat and uniform; good Maofeng tea buds Haoduo, Yafenglu and so on. If the cords are loose, the grains are loose, the leaves are rough, and the bones are light, it is not considered good tea.

Smell the aroma - all types of tea have their own aroma, such as green tea with a delicate aroma, top-grade green tea with orchid aroma, chestnut aroma, etc.; black tea with a refreshing aroma and sweet or floral aroma; oolong tea with ripe peach aroma wait. If the aroma is low, it is considered inferior tea; if it has a stale smell, it is old tea; if it has an odor such as mold, it is considered spoiled tea. Even Kuding tea has a natural aroma. Scented tea attracts tea drinkers with its strong fragrance.

Taste the taste----The taste of tea itself is composed of various components such as bitter, astringent, sweet, fresh, sour and so on. With the right proportion of ingredients, the taste will be fresh and mellow. At the same time, different teas have different tastes. The best green tea has a bitter taste at first taste, but the aftertaste is rich and mellow, making the mouth salivate; the old and inferior tea is bland and tasteless, and even Astringent mouth, numb tongue. High-quality black tea has a strong, strong, and refreshing taste; low-grade black tea is bland and tasteless. Kuding tea is very bitter in the mouth, but it has a sweet aftertaste. The quality of the tea can be evaluated by its appearance, color, and taste. Generally speaking, the color of dry green tea is dark green or emerald green, and the soup color is yellow-green. Bright, with a pleasant chestnut aroma; Oolong tea is generally in the shape of strips or granules, with bright orange-yellow soup color, mellow and fresh taste, and a natural floral aroma. Black tea can be divided into broken tea and bar-shaped tea. Broken black tea has good uniformity in appearance, dark brown and oily color, red and bright soup color, strong and fresh taste, and bar-shaped black tea has tight knots in appearance and red soup color. Bright and bright, the taste is rich and fresh. These characteristics are the embodiment of good tea. When buying loose tea, you can use two fingers to pinch the tea stick. If it can be ground into powder, it means the tea is dry and its moisture content is about 6%-7%, which is a qualified standard. If it cannot be ground into powder but can only be ground into fine flakes, it means that the tea has absorbed moisture and is not dry enough. Its moisture content is often above 9%. It is not suitable to buy tea with such high moisture content. In addition, pick up some products that smell like tea and have no moldy smell, which are normal products. When purchasing small-packaged tea, you should read or ask for the packaging date. Generally, small-packaged tea that is more than one year old is prone to moisture absorption and deterioration. In addition, when purchasing, pay attention to identify the quality and integrity of the packaging and the moisture-proof performance of the packaging materials.
