Cha Qi
Cha qi (茶气, tea energy) is the bodily sensation some drinkers report from strong teas, such as warmth, alertness or relaxation, most often linked to aged and old-tree pu'er.
Definition
Cha qi (茶气, chá qì) means "tea energy." Drinkers use it for the physical feeling a tea produces beyond its taste: warmth spreading through the chest, a sweat on the forehead, a calm and focused state, or a heavy, relaxed body. The term borrows qi from traditional Chinese thought, where it describes vital energy. In modern tea culture the word appears most around pu'er, especially sheng pu'er from old trees (gushu) and well-aged cakes. Sellers often describe a tea's cha qi as strong, gentle, or "heady," and some buyers weigh it as heavily as flavor when paying for premium leaf. There is no measurement for cha qi, and two people drinking the same pot can report different effects. A reasonable reading is that it combines real physiology with expectation. Caffeine and L-theanine both act on the body, gongfu sessions deliver many small cups in a short time, and hot liquid itself raises skin temperature. None of that proves a special property of old-tree leaf. Treat cha qi as a descriptive word that experienced drinkers use, not as a quantified attribute.
In Depth
Most reports of strong cha qi come from long gongfu sessions: 7-8 g of pu'er in a 100 ml gaiwan, 10 or more infusions, an hour or more of drinking. Over that span a drinker can take in roughly as much caffeine as two or three cups of black tea, so part of the effect is plain dose.
If you want to notice it, drink on a calm stomach (not empty), keep cups small, and pay attention to body warmth, breathing and focus over 30-60 minutes. Compare a young factory sheng with a more expensive single-mountain cake on separate days rather than back to back.
Be skeptical of sellers who cite cha qi as the main reason a tea costs several times more. It cannot be verified on a label. Taste, huigan, leaf quality and storage can be checked directly; cha qi is a personal impression.
