The Qianjiazhai Dongsa Cooperative was established to be a steward to the oldest tea forest in the world, finishing every leaf using hand processing and stone-pressing techniques.
The cooperative's Zun series pressings is a careful blend of maocha from trees aged between about three hundred and eight hundred years old, picked for a balanced and rich full body and aroma. These old trees grow in one of the oldest and most remote tea forests in the world, on Mt. Ailao. Every leaf is hand picked and sun-dried.
