I drink many brands of tea, such as Zhongcha, Sanhe, and Dayi. There are also some farmers’ teas. Some classes with a long history require tasting unbranded farmer’s tea to gain a deeper understanding. For teas like puerh tea and Liu bao tea, which become more fragrant as they age, finding tea sources from farmers’ tea is also a very important way to enjoy aged tea. But for non Chinese residents, it’s very unconvenient to find old tea. In addition to searching on Amazon, I also go to teayucafe.com to buy Chen puerh tea and Old Liu bao tea. Sent directly from China.
