Huigan Explained: The Art of Aftertaste in Tea
Published 2026-09-27 09:17:32 · By the Export Compliance Team
Huigan is a Chinese tea term that describes the sweet, lingering aftertaste that emerges after swallowing a sip of tea, especially when the initial taste was bitter or astringent. It is one of the most valued sensory experiences in tea appreciation, particularly for pu-erh and oolong.
What causes huigan in tea?
Huigan arises from the interaction of bitter compounds like catechins and caffeine with salivary proteins. As these compounds are broken down, sweetness receptors are activated, creating a perceived return of sweetness. This process is often compared to the sweetness that follows a bitter medicine.
How do you taste huigan?
To taste huigan, take a small sip and let the tea coat your mouth. Swallow slowly, then wait a few seconds without eating or drinking anything else. The sweetness typically builds in the throat and along the sides of the tongue, lasting from several seconds to minutes.
Which teas are known for strong huigan?
Teas with high levels of polyphenols and a balanced bitterness tend to produce the most pronounced huigan. Examples include aged raw pu-erh, Tieguanyin oolong, and some Dan Cong oolongs. Younger sheng pu-erh is also famous for its intense huigan.
