Yellow tea review
The shape of yellow tea is obviously different due to different varieties and processing techniques. For example, Junshan Silver Needle Tea is in the shape of a needle, the bud head is fat and full of hair, and the bud is thin and flat, little is bad. The masked yellow buds are flat and straight, the buds are strong, and the buds are curved and thin. Luyuan tea with the cable tight knot curling ring, Xianhao for the best, the strip is loose and straight, not obvious for the poor. In Huangda tea, it is better to have thick leaves, long and strong stems and connected leaves, while leaves like leaves, thin and short stalks, separated stem leaves or broken stem leaves are worse. The dry and dark color is better than yellow, golden yellow is the best, the color is dry and dark, and the cleanliness is higher than that of stem, tablet, powder and non-tea inclusion. The aroma of dried Huangda tea is better than that of Guoba incense, followed by muggy gas or rough green gas. In the evaluation of endoplasmic soup color, the bright yellow soup is the best, and the yellow dark or yellow turbid is the second. The aroma of Qingyue is excellent, while that of turbid gas is poor. Taste to mellow and fresh, back to sweet, weak convergence is better; bitter, astringent, light, stuffy secondary. At the bottom of the leaves, the buds and leaves are fat, smooth and bright yellow, while the buds are thin and dark.
