Zang Cha (Tibetan Dark Tea)
Zang cha, literally 'Tibetan tea,' is the dark, post-fermented border tea made in Ya'an, Sichuan, and traded into Tibet for over a thousand years along the tea horse road. It is known for one of the longest, most elaborate processing sequences in tea, with many rounds of piling and fermentation that yield a very dark, exceptionally smooth, low-bitterness cup. It is the everyday staff-of-life tea of the Tibetan plateau, drunk all day as salted butter tea.
Authentic Ya'an Tibetan tea is built from mature leaf and stem yet should taste remarkably smooth and round, almost free of bitterness, which is the payoff of its long multi-stage fermentation. Look for a very dark, clear liquor, a mellow woody-sweet body, and a clean finish. Some stem and a rustic leaf are part of the style, not a defect. Sour, sharp, or musty notes indicate poor fermentation or damp storage. It is sold both as loose tea and in pressed forms such as bricks.
Ya'an in Sichuan is the recognized home of zang cha, the heart of the south road border tea tradition. The processing is unusually long, with the leaf repeatedly piled, turned, and fermented over an extended period, which is what strips out bitterness and produces the signature smoothness. It is pressed into bricks (including kang zhuan and jin jian) or packed loose for transport over the mountains to Tibet, where it underpins daily butter-tea culture.
Gongfu: 6-8 g per 100 ml, 95-100°C, one rinse, then 10-20 second steeps extending gradually, good for many infusions. Western: 4-5 g per 250 ml, 95-100°C, 3-4 minutes. Pressed forms need breaking. Traditionally it is boiled or simmered at length and churned with yak butter and salt, or served with milk and sugar.
€4-20 (about $4-22) per 100 g, from cheap everyday brick to tidier loose grades.

Kang Zhuan
Kang zhuan is one specific pressed brick of zang cha; the brick is a subset of this broader Ya'an Tibetan tea category.
Qing Zhuan
Both are border dark teas, but zang cha serves Tibet from Sichuan while qing zhuan served the northern Mongolian and Russian trade from Hubei.
Liu Bao
Liu Bao is a smoother sipping dark tea from Guangxi; zang cha is built for boiling into butter tea, not for gongfu sipping.
Aged Shou (5+ years)
Aged ripe puerh and zang cha both prize dark smoothness and low bitterness, but puerh comes from Yunnan wet-pile fermentation and is drunk on its own.
Ya'an Tibetan tea is often cited for having one of the most labor-intensive processing sequences of any tea, with many separate steps and repeated fermentation rounds, a complexity that evolved to turn rough, mature leaf into the smooth, boil-all-day tea the plateau depends on.
