In short: Hangzhou Kainong Factory is a tea production facility in Zhejiang province, China, operated by Zhejiang Hangzhou Kainong Ecological Technology Co., Ltd. and certified by the Ethical Tea Partnership.
Hangzhou Kainong Factory is a tea production facility located in Zhejiang province, China, at an elevation of 26 metres. The operation is managed by Zhejiang Hangzhou Kainong Ecological Technology Co., Ltd. The factory produces green, oolong, and black teas, and holds certification from the Ethical Tea Partnership.
Terroir & Climate
At 26 metres above sea level, Hangzhou Kainong Factory sits at a low elevation typical of coastal and river-plain tea-growing zones in Zhejiang. Estates at this altitude generally experience milder temperature variation and longer growing seasons than their high-elevation counterparts, with warmer conditions tending to accelerate vegetative growth. The latitude of approximately 29.6°N places the site in a subtropical zone where tea cultivation typically benefits from ample rainfall and a climate moderated by proximity to the East China Sea.
Low-lying estates in Zhejiang often contend with higher ambient temperatures and humidity during the growing season, conditions that can favour rapid flush cycles. While such environments may lack the cool nights associated with slower, more concentrated leaf development, they tend to support vigorous plant growth and can be well suited to the production of volume-oriented green teas as well as styles that benefit from a brisker character.
Tea Produced
The factory produces green, oolong, and black teas. Zhejiang is historically synonymous with green tea production, and estates in the region typically yield styles ranging from delicate, pan-fired greens to more robust, high-fired types. Low-elevation sites such as this one generally produce leaf that tends toward briskness and straightforward vegetal character rather than the nuanced sweetness or floral notes often associated with higher-altitude gardens. Oolong and black teas made at low elevations in the province are less common but can offer malty, direct profiles with moderate astringency.
