Yellow tea is a rare and expensive type of tea that is mostly produced in China. This tea is a derivative of green tea, made by allowing the leaves to undergo a slow oxidation and drying process, which gives it a unique flavor and aroma. Yellow tea is also known for its rich and mellow taste, with a slightly sweet and floral aroma. It has a pale yellow color and a smooth texture, with a subtle grassy taste. Because of its rarity and complexity, yellow tea is considered a delicacy among tea connoisseurs.
