Purple tea refers to a unique variety of tea that is distinct due to its natural purple color, which comes from a specific type of tea plant. This purple hue is a result of a high concentration of anthocyanins, the same type of antioxidants found in other purple-colored foods like blueberries and red grapes. Purple tea is primarily grown in Kenya, China, and a few other regions.
In terms of taste, purple tea is often described as having a sweet and smooth flavor, sometimes with a hint of floral or fruity notes. It is known for its numerous health benefits, which include high antioxidant levels that may help in protecting the body against free radicals.
When processed as a Puerh tea, as in your description, it combines the unique properties of purple tea leaves with the characteristics typical to Puerh tea, such as a deep, earthy flavor and the potential for aging, which can enhance its taste and health benefits over time. The natural storage in Guangzhou, as mentioned, would contribute to its aging process, potentially developing more complex flavors and aromas.
