Huigan
A Chinese evaluative category: the sweetness that arrives after the swallow, following bitterness rather than replacing it.
Huigan names something specific enough that Chinese tasters use it as a criterion and English has no single word for. A mouthful of young sheng or of a good Dan Cong is bitter going down; then, ten or twenty seconds later, a sweetness rises in the mouth and throat that was not there during the sip. The bitterness is not a flaw the sweetness redeems — the sequence is the point, and a tea whose bitterness simply fades without a return is judged differently from one that has huigan. It is treated as a marker of quality and of material, and it is one of the things a buyer is checking for when tasting maocha. TeaHQ records it as a category from a particular tradition of assessment rather than as a sensory primitive, because that is what it is. Glossing it as 'sweet aftertaste' is not wrong so much as it is a different, smaller statement: it drops the requirement that something preceded the sweetness, and it drops the evaluative weight the term carries in the tradition that uses it. Whether huigan is one sensation, a sequence of two, or a description of how a taster attends to the finish is not something TeaHQ is in a position to settle, and this record does not.
Which sense this is
Finish and throat. What happens after swallowing. Includes evaluative categories from Chinese tea assessment that have no equivalent term in European sensory language.
Filed on the finish axis rather than on taste, deliberately. Calling it a taste would assert that the tongue is registering sweetness on a delay, which is a claim about how perception works that the term itself does not make and TeaHQ cannot support.
Tradition-specific category. A category belonging to one tradition of tea assessment, with no equivalent term elsewhere. Recorded on its own terms rather than translated into one.
Whose category this is. Chinese-language tea assessment, especially of sheng pu-erh, Dan Cong and yancha, where it is used as a criterion of quality rather than as a tasting note.
Where it comes from
- Observed, cause unsettled
Widely and consistently reported, and not explained. Popular accounts attribute it to particular compounds or to a rebound after bitterness; TeaHQ records the observation, the tradition that names it, and the absence of a settled mechanism.
Reliably observed and not explained. Recorded as unexplained rather than given a mechanism it has not earned.
Types: type-dark-tea, type-oolong-tea.
Not to be confused with
- Sweetness (Taste) — A taste, and in tea usually a faint one — most of what reads as sweet is aroma.
What gets said that is not right
That it is simply the English 'sweet finish'. The term requires a sequence — something bitter or savoury first, then a return — and it is used as a judgement about the tea, not as a description of a flavour in it.

A tasting note is a comparison, not a measurement. Where the route from leaf to sensation is established it is labelled as such above; where it is not, the page says so rather than supplying a mechanism the descriptor has not earned. See the rest of the vocabulary for how the axes divide up.
