Butter tea churn (chandong)
A tall narrow wooden cylinder with a close-fitting plunger, used to work boiled tea, butter and salt into an emulsion. The proportions are the design: a narrow bore means the plunger displaces the whole column of liquid on every stroke, which is what breaks the fat into droplets small enough to stay suspended.

Porous — this changes how it is used
Porous. It takes up a trace of every tea brewed in it and gives some of that back to the next, which is why such a vessel is kept for one tea rather than shared across a shelf.
Untreated wood takes up fat, and a churn in regular use is permanently seasoned with it. That is normal and expected; it also means a churn cannot be repurposed and cannot be left uncleaned for long.
Where it comes from
Tibetan and Himalayan, in daily household use across the plateau and neighbouring regions. Household practice varies widely and no single version is the standard one.
Named here rather than presented as generic equipment. The object belongs to a practice, and TeaHQ describes it from the outside.
If you do not own one
A blender does the same physical work in seconds and is widely used in Tibetan households today. A whisk does not — stirring leaves the fat floating rather than suspended.
This one is not marked essential. The tea can be made without it.
Brewing methods it is used for
- Butter tea churning — Brick tea boiled at length, then churned with butter and salt into an emulsion. It is a daily staple across the Tibetan plateau and neighbouring highlands, and calling it a savoury drink undersells what it is: the churning changes its physical state, not just its seasoning.
Tea types it suits
Care and maintenance
Rinse hot and dry thoroughly; rancid fat in the grain of the wood is the failure mode. Do not soak, which swells the staves and loosens the bands.

Sources
This page is TeaHQ synthesis. No external source stands behind the description, the material or the account of how the object is cared for. Where the record names a tradition, that attribution is TeaHQ’s own reading of common practice rather than a citation.
TeaHQ names no maker, brand or shop and has nothing to sell. Nothing on this page should be read as advice to buy the object — the substitute note above exists because owning it is usually optional.
Written comparisons

- Butter tea churn vs bamboo whisk — Two tools for suspending something in tea that will not stay suspended on its own, from two traditions with different physics. The chasen suspends fine powder in water; the chandong emulsifies fat into it, which is a harder problem and needs a plunger rather than a whisk.
