Tibetan butter tea (po cha / 巴茶)
Po cha, Tibetan butter tea, is brick tea boiled for hours then churned with yak butter and salt into a rich, savoury, soup-like brew — a high-altitude staple and a cornerstone of Himalayan hospitality.
On the Tibetan Plateau, tea is fuel as much as ritual. Po cha (巴茶), butter tea, begins with a slab of dark brick tea crumbled into water and boiled for hours into a potent, smoky base called chaku. A portion is poured into a tall wooden churn (the chandong or dongmo) with a lump of yak butter and a pinch of salt, then churned vigorously until it emulsifies into a warm, creamy, savoury drink closer to a light soup than a Western cup of tea. In the harsh, thin air of the Himalaya this is essential nourishment — rich in fat and calories, it wards off cold, chapped lips, and altitude fatigue, and Tibetans may drink it many times a day. It is also the language of hospitality: a guest's bowl is topped up after every sip and should never be drained empty, and endless refills signal welcome. Butter tea threads through monastic life, festivals, and the ordinary rhythm of every Himalayan home.
How it's prepared
Brick tea is boiled long and hard into a concentrated brew (chaku), which is then churned in a wooden cylinder (chandong) with yak butter and salt until smooth and emulsified, and served piping hot (tibetan-butter-tea method).
The vessel
The signature tool is the tall wooden churn (chandong / dongmo) used to blend butter into the tea; it is drunk from small bowls, traditionally wooden, which a host keeps refilling.
Its social role
Butter tea is the heart of Himalayan hospitality — a host continually replenishes a guest's bowl, and it is served at gatherings, monasteries, festivals, and daily in every home as both sustenance and a sign of welcome.
What accompanies it
Tsampa (roasted barley flour), often stirred into the tea or eaten alongside; dried yak cheese and other high-plateau staples.
