Butter tea — known in Tibetan as po cha — is a warming, savoury drink of strong brewed tea churned together with butter, traditionally yak butter, and a pinch of salt. A high-altitude staple across Tibet, Nepal, Bhutan and the wider Himalayas, it tastes far more like a light, rich broth than a sweet cup of tea. This guide explains what butter tea is, where it is drunk, how it is traditionally made, why butter and salt belong in a teacup, and how to make a simpler modern version at home.
What butter tea is, and where it is drunk
At its simplest, butter tea is brewed tea emulsified with fat and salt until it turns thick, glossy and slightly frothy. It is often called yak butter tea after its most traditional fat, and in Tibetan it is known as po cha (also written bho jha) or cha süma, meaning 'churned tea.' In Mandarin it is sūyóu chá, and in Ladakhi gur gur cha, after the burbling sound of the churn.
The drink belongs to the high, cold plateaus of the Himalayas. It is a daily ritual across Tibet, Nepal and Bhutan, and versions of it are drunk through the mountain belt that reaches into Central Asia and the western regions of modern China. In many Tibetan households a bowl is topped up again and again through the day, and it is always offered to a guest as a gesture of welcome. Because the tea leaves themselves usually arrive as compressed brick tea traded over long distances, butter tea sits at the meeting point of two very different food cultures — the tea-growing valleys to the east and the pastoral, butter-rich highlands.
How butter tea is traditionally made
Traditional preparation starts with a long, dark brew. A piece is broken from a slab of brick tea — often a coarse, smoky, pressed tea in the pu-erh family — and simmered in water for anywhere from an hour to half a day, until the liquor is almost black and faintly bitter. This concentrated base is sometimes called chaku.
The hot tea is then poured into a tall, narrow wooden churn known as a chandong (or cha dong), along with a knob of butter and a good pinch of salt. A plunger is worked up and down for a couple of minutes until the fat is fully emulsified and the surface turns foamy. The result pours out warm, opaque and about as thick as a light stew or thick oil. Traditionally the butter comes from the dri, the female yak — despite the popular name yak butter tea, male yaks give no milk — and older, tangier butter is often prized for its punchy flavour. Some households also stir in tsampa, roasted barley flour, to make the bowl more filling.
Why butter tea uses butter and salt
The recipe is a direct answer to life at altitude. Much of the Tibetan plateau sits above 3,500 metres, where the air is thin, cold and extremely dry and calories are hard-won. Butter tea packs a lot of energy into a single warm bowl — roughly 150 to 250 calories a cup, depending on how generous the butter is — which fuels physical work in the cold and helps the body hold its heat. The salt replaces minerals lost through exertion, and, much like an electrolyte drink, it makes the fluid easier to keep sipping all day long.
The fat does more than feed you. A film of butter is said to soothe and protect chapped lips and skin against biting wind and dry mountain air. And because the tea is taken in many small servings rather than one big mug, it keeps a steady trickle of warmth, hydration and energy going from morning to night.
What butter tea tastes like
If you are expecting something sweet, butter tea will surprise you. It is savoury, buttery and salty, with a rounded, creamy body and a gentle bitterness from the long-brewed tea underneath. Many first-time drinkers say it reads more like a thin, salted broth or a light soup than a cup of tea — closer to a consommé than to a latte. Traditional versions made with aged yak butter can taste frankly rich and a little cheesy or 'rancid' to an unaccustomed palate, while fresher, milder butter gives a cleaner and more approachable result. Served piping hot, it is genuinely comforting, especially in cold weather.
Butter tea ingredients and what each one does
| Ingredient | Role in the cup |
|---|---|
| Strong brewed tea (brick or black) | The backbone — a long, dark brew gives colour, gentle bitterness and a little caffeine. |
| Butter (traditionally yak or dri butter) | Richness, body and dense calories; emulsifies into the tea to make it creamy and warming. |
| Salt | Turns the drink savoury and replaces minerals lost at altitude; balances the fat. |
| Water | The brewing medium, boiled long and hard with the tea to build a concentrated base. |
| Milk or cream (common in modern versions) | Softens the flavour and lends a smoother, lighter creaminess. |
| Tsampa / roasted barley (optional) | Sometimes stirred in to make the bowl more filling, edging it toward a light porridge. |
How to make a simple modern butter tea
You do not need a chandong or a yak to try butter tea at home. A blender does the churning, and ordinary ingredients stand in for the traditional ones. For a single mug, brew a cup of strong black tea — steep it longer and darker than usual so its flavour can stand up to the fat. Pour the hot tea into a blender with about a teaspoon of butter, a splash of milk or cream, and a small pinch of salt.
Blend for a minute or two until the drink is smooth, frothy and evenly emulsified, then taste and adjust: more salt for savouriness, more butter for richness, more tea for backbone. That is the whole method — a fair summary of how to make butter tea without any special equipment. Unsalted butter gives you the most control over seasoning, and even a small pinch of pink or sea salt goes a long way.

Butter tea's cousin: bulletproof butter coffee
If churning fat into a hot drink sounds oddly familiar, that is because the idea travelled. The modern 'bulletproof' fashion for blending butter into coffee is, in spirit, a direct descendant of Himalayan butter tea — its populariser has openly credited a restorative cup of yak butter tea in the mountains as the inspiration. The logic is the same: fat adds richness, staying power and slow-release energy to a caffeinated drink. If you want the coffee version, see our guide on how to make bulletproof coffee, which relies on the same blend-until-frothy trick.
Butter tea is one of those drinks that only makes complete sense in its home landscape — a savoury, high-calorie brew built for thin air and hard cold, and shared as a sign of hospitality. Whether you sip it from a bowl in the Himalayas or whir up a quick modern cup in a blender, it is a reminder that the word 'tea' can mean something very different depending on where in the world you are drinking it.
