[Features of Rare Winter Tea] Because it grows slowly and thick, storing a lot of nutrients in its leaves, it has a sweet, mellow richness and a soft mouthfeel. The manufacturing date is unknown as it is unopened, but the expiration date is listed as 2 years. I received this as a souvenir from Taiwan at the end of January 2025, so please rest assured. I am selling it because I don't drink it. Tea cultivated in Shizhuo, Zhushan Township, within Alishan is sold under the name Alishan Zhulu Tea, and it seems to be a high-grade tea. I will send only the contents without the case.
