Liyang City is a renowned tea region that has produced premium tea since ancient times. In 1999, the city established the Tianmu Lake White Tea brand, which became the highest-grade offering among Liyang white teas. It is characterized by vibrant green veins, jade-white leaf buds, a fresh and mellow sweet taste, and neat, uniform strips. Because spring yields the best quality Tianmu Lake White Tea, top-grade harvests can only be picked once—sometimes yielding only one bud and one leaf per pluck—making it quite expensive. Authentic, traditionally crafted Tianmu Lake White Tea typically costs over NT$1,500 per 500 g, and even then, availability is not always guaranteed.
