First, the true and false identification of kuding tea leaf 1.5-2 times larger than ordinary leaves, oval leaves, thick leaves, leathery, no hair. Fresh leaves are glossy and dark green. The tea made from buds leaves has a thick, curly, velvety appearance. Brewing can be judged authenticity: Kudingcha taste is first bitter (this bitter taste is acceptable bitter taste) and then slightly sweet taste, no astringent, spicy, odor, acid and other odor, resistant to brewing. 1 g of kudingcha made from young leaves can be brewed with 150ml of water, and its tea is rich in flavor. Brewing 8 times -10 times is still very strong, which is difficult to compare with ordinary tea. The tea leaves made from old mature leaves have a taste of first bitterness and sweetness, no savory taste, slow release of taste, and resistance to brewing is the main feature. Add 2-4 times the amount of tea taste is only slightly stronger, its bitter taste is still fresh, sweet, will not become bitter and unbearable. It is difficult to make with other leaves and even adding some substances. Back sweet taste, sweet taste, may be added licorice or sugar. If you have a taste may be gynostemma or other parameters. Check the end: Kuding tea bottom with purple brown, no hair, large and thick leaves, thick tea stems. The old leaf area of ​​the whole piece is large, and the leaf margin teeth are relatively pure. Second, the identification of heterogeneous tea that is mixed with other substances in Kuding tea, with senses is distinguishable. Ordinary tea is lighter in size and smaller in appearance, and the leaves are small and thin at the bottom of the leaf. Coarse-grained powders may be mixed with other substances. The most convenient and effective method is to take about 2 grains of suspicious foreign material and put it in the mouth to cut the pressure with the incisors. Authentic in the mouth can feel bitter. After bitterness and sweetness, poor quality products have no bitterness or bitterness, or bitterness or other odors. Licorice has only sweet taste without bitterness. Third, the quality of identification Kuding tea is a health drink, its evaluation is different from ordinary tea, whether resistance to brewing is the main, high-grade Kuding tea taste thick and mellow, first bitter after Gan, the cord is more tight and clean. The plate: After screening, shaking, collecting tea samples, no broken debris, more tea in the middle, heavy skeletal is better, the old leaf tea cut evenly. Open soup: Weigh 3 grams of tea, use a 150ml cup, open blisters for 5 minutes. Sniffing aroma: Aroma is not obvious at the bottom of the leaf. It is relatively flat, and the smell of heat and cold smell is normal and there is no mildew or coke. Taste: After bitterness and sweetness, bitterness is acceptable alcoholic taste, no odor is better. Sweet taste, but the taste glycol, back to sweet taste is not strong, no sweetness as well. After drinking, the mouth and throat feel clean, sweet and odorless. If the quality of the product is sour, bitter, spicy, and burnt, it is not good enough, even if it is adulterated, it must be re-examined. Anti-foaming test: Kuding tea is resistant to brewing, its taste is slowly released, and continuous brewing (5 minutes each time) is still more than 10 times the taste is very good. Deodorization is quick and slightly lighter. Look at the soup color: Kudingcha is best known for its yellow, green, clear, no cloudiness or suspended matter. Comment on the bottom of the leaf: It is better to use indigo or dark cyan, soft, leaves without focal spots, and no debris. Tea slag, soup shelved: Kudingcha brewed with a net boiling water, tea soup is generally not odor for 3 days to 5 days, and taste is as good as ever. When the brewing tea is poured without any water droplets, the tea slag is not likely to be mildewed in the cup for 3 days to 5 days, and the water is re-opened and the tea taste remains. The kuding tea made from the old leaves has a similar taste to that of the young leaves, but it has a slightly lower bubbling resistance, and the brewed tea tastes lighter. If slightly increase the amount of tea, drinking taste is still better.
