Tea does not grow on the Tibetan plateau — it was driven in along the Tea-Horse Road from Yunnan and Sichuan over many centuries, and the technique of churning that hard-won brick tea with butter and salt is a Tibetan adaptation to the high-altitude calorie problem. Yak butter is dense in fat and calories; the salt replaces what sweating loses; the strong tea provides caffeine and cuts the richness. Three problems solved in one drink.
Sip — warm, opaque, distinctly salty, faintly tannic from the brick tea. The fat coats the throat and lips, the salt sharpens the savory minerality. Drink three cups in a Khampa nomad's tent and you've had your morning meal. Don't gulp it — sip and keep the bowl topped up.
Vigorous churning forms a tea-fat emulsion — same physics as homemade mayonnaise. The butter fat and water-soluble tea polyphenols don't naturally mix, but mechanical action breaks the butter into microscopic droplets coated by tea proteins, creating a stable opaque liquid. Salt strengthens the emulsion. Without churning, the butter just floats on top. Modern kitchens use a blender in place of the wooden churn.
Variations
Bhutanese suja (similar but creamier). Mongolian suutei tsai (salted milk tea, no butter). Sweet po cha (with sugar, a modern variant — purists object). Lighter po cha (less butter, for warm weather). Po cha stirred into tsampa flour as breakfast porridge.

Where Po Cha sits in the Tibetan flavor cloud
The whole drink lives or dies on the emulsion: churn hard enough long enough that the butter breaks into invisible droplets, or it just floats as an oil slick on top.
Ingredients
Serves 2How it's made
5 steps · 10 min active + 5 min waiting
- 111 min
Brew strong black tea: simmer 2 tbsp loose Tibetan tea (or strong black tea) in 1 liter water for 10 minutes; strain.
Watch outTea should come out dark, near-bitter — that strength is what balances the fat later.
- 21 min
Pour hot tea into a traditional churn (chandong) — or a tall blender if traditional churn unavailable.
- 31 min
Add 3-4 tbsp yak butter (or unsalted dairy butter as substitute) and 1/2 tsp salt.
- 44 min
Churn vigorously with the wooden plunger 3-5 minutes — or blend at high speed 30 seconds — until the tea becomes opaque, frothy, and emulsified, with no visible butter pieces.
Watch outStop only when it's uniformly opaque and frothy with no butter specks left floating.
- 51 min
Pour into wooden bowls (po pa) or small ceramic cups while still hot. Serve immediately; reheat between rounds.
