Yellow tea is a very rare type of tea, belongs to lightly-fermented tea and produced only in China.
The invention of yellow tea is believed to be the result of a mistake in the green tea production, the tea leaves turned to yellow because of the lightly-fermented.
But after the tea master brewed the “fail tea” and tasted it, they found it was awesome. After continuous technological improvement, it became the yellow tea we drink today.
Most of the yellow tea shows yellow, with a rich aroma and a slightly sweet taste, rather than the herbal and bitter taste of green tea.
Because of the lower yield and the complicated processing method, yellow tea is very precious. And yellow is the exclusive color of the emperor in ancient China, so in ancient times, yellow tea is generally only provided to Chinese royal family members or rich people.
Tea polyphenols are the main nutrition fact in tea and play an important role in the benefits of yellow tea. Because the yellow tea was been lightly-fermented, some of the polyphenols in the tea are oxidized to other nutrients and enhance the flavor of the tea. And the polyphenols retained by the dried yellow tea were second only to green tea.
Yellow tea contains a variety of vitamins, such as water-soluble vitamins B1, B2, B3, PP, B6, B11, inositol, and vitamin C, also fat-soluble vitamins E, K, P, and vitamin A, effective prevention and treatment of various vitamin deficiencies.
Yellow tea contains nearly 30 amino acids, especially lysine, phenylalanine, threonine, methionine, leucine, isoleucine, tryptophan, and valine 8 what people need. The amount of amino acids in yellow tea high to 2%-4%, they are the main ingredient to make yellow tea a unique flavor.
Just like white tea, yellow tea is only lightly-fermented, and the enzymes in the tea are converted to soluble carbohydrates and retained. Its soluble carbohydrate content is second only to white tea, so yellow tea also tastes slightly sweet.
Yellow tea is rich in important minerals: especially Se, Fl, Mn, Mg, Zn, Mo and more than 10 kinds of trace elements that have important functions for the human body.
Yellow tea is true tea, so it contains a certain amount of caffeine. The caffeine content of yellow tea is between 2% and 5%, lower than that of green tea and white tea. However, the caffeine content of yellow tea after brewing is affected by the brewing way and steeping time.
Yellow Tea Benefits

In digestive enzymes and caffeine under the synergistic effect, yellow tea can accelerate the burning and reduce the accumulation of fat, give a certain help to your weight loss plan.
Scientific studies have shown that the antioxidants contained in yellow tea can help eliminate free radicals in the body and effectively prevent the occurrence of cancer (especially the liver, and stomach cancer). And the antioxidant capacity of yellow tea was not reduced by lightly-fermentation, the research shows even higher than that of green tea.
Protect The Liver
The liver is an important organ for balancing glucose and lipid metabolism. Yellow tea has a significant effect on the prevention and treatment of hepatitis and can help to treat other liver diseases. The healthy liver function also plays an important role in the weight loss plan.
Yellow tea has excellent anti-inflammatory properties just like other types of tea. The research shown that the extract of yellow tea can effectively treat gastritis and hepatitis, and prevent stomach injury, has great help to keep the stomach healthy.
Thanks to the ability of tea polyphenols to scavenge free radicals, yellow tea can also help anti the aging. For women, having yellow tea helps reduce skin wrinkles and spots, making it a popular anti-aging beauty tea.
Yellow tea is only produced in China, and the Korean yellow tea just called the same, is not true yellow tea. Because of the difficult production way, even in China, only Sichuan, Anhui, Hunan, Yunnan, Guangdong and some other provinces are producing yellow tea. And the yellow tea production technology is slightly different in each origin, so that yellow tea also has a variety of types.
Yellow Tea Processing
Yellow tea is processed in much the same way as green tea, but with an extra step called “Sealing Yellow“. “Sealing Yellow” means after the raw tea leaves fixation, packing them with a wet cloth and place for a time. Let the green tea leaves oxidized and turn to yellow, and the nutrients in the tea will also be changed to different degrees. Some tea gardens will steam the tea package during “Sealing Yellow”.
Different tea gardens have different ways to “Sealing Yellow”, but the purpose is the same – make the tea leaves reach an ideal degree of oxidation before drying, to obtain benefits and flavors different from other types of tea.
Because this processing method is very difficult, the yield of high-quality yellow tea is very low, which leads to the preciousness and high price of yellow tea.
