Purple Leaf "Zi Cha" Black Tea
Purple Varietal of Camellia Yunnan pu-erh tea grows in the superior environment of low latitude, high altitude South Asian tropics and achieves many qualities of superior tea. Among pu-erh tea, purplish red bud tea is particularly valued. During the hot, humid summer and fall seasons a portion of tea tree buds are purplish red colored. The source of the color is anthocyanin, which changes color along with cell sap acidity. High levels of acidity lead to red color, while medium acidity is more purple, and high alkalinity tends toward indigo.
