Guanxin Tea owns its own tea garden located in the Ruifeng high-altitude production area of ​​Meishan, Chiayi County, and collaborates with small farmers in the same production area to select and harvest tea, and processes and adjusts the flavor at the production site.

Meishan Ruifeng's high altitude, abundant clouds and fog, and large temperature difference between day and night slow down the growth of tea leaves, resulting in a rich and robust flavor. The core strength of Guanxin Tea lies in its transformation of the two representative varieties of the production area, Gaoshan Jin Xuan and Gaoshan Qingxin Oolong , into multi-layered flavor profiles through different degrees of fermentation and roasting control.
