A common misconception spread by premium‑grade teas is that the younger the plucking material and the earlier the harvest date, the better the tea. This logic largely holds true for premium green tea and premium black tea; their Super‑Grade and Grade‑One products are generally plucked at one‑bud‑one‑leaf or one‑bud‑two‑leaf standard.
Nevertheless, harvest timing should be determined by weather conditions and the actual growth status of tea shrubs. In case of abnormal weather such as late spring frost, a delayed harvest compared with previous years is perfectly normal.
For bulk‑produced green tea, plucking mostly takes place after the Qingming Festival at one‑bud‑two‑leaf to one‑bud‑three‑leaf. For raw materials used in tea‑bag production and catering‑grade tea, one‑bud‑three‑leaf to one‑bud‑four‑leaf is quite common.
Price is a key factor here. Green tea and black tea made from one‑bud‑one‑leaf / one‑bud‑two‑leaf raw materials command noticeably higher market prices than those made from one‑bud‑three‑leaf or one‑bud‑four‑leaf.
Oolong tea requires raw leaves to reach a certain level of maturity before harvest, following the well‑known practice of banjhi‑plucking (open‑face plucking).
• Light open‑face: The top‑most leaf reaches roughly half the area of the second leaf.
• Medium open‑face: The top‑most leaf grows to about two‑thirds the size of the second leaf.
• Full open‑face: The top leaf develops to nearly the same size as the second leaf.
Specific standards vary slightly among different oolong varieties. For instance, Tieguanyin is usually harvested at light‑to‑medium open‑face with two to three leaves on each shoot.
Wuyi rock tea prefers medium‑to‑full open‑face plucking of three to four leaves per shoot. White‑tea plucking standards differ by category. Silver Needle consists purely of unopened buds. White Peony uses one‑bud‑one‑leaf or one‑bud‑two‑leaf. Gongmei and Shoumei are made from mature one‑bud‑three‑leaf to one‑bud‑four‑leaf shoots. Historically, yellow tea fell into three groups: bud‑type yellow tea, small‑leaf yellow tea and large‑leaf yellow tea. After the implementation of Chinese national standard GB/T 21726‑2018 for Yellow Tea, categories were revised into bud type, bud‑and‑leaf type, and multi‑leaf type.
• Bud type: single bud or newly unfurled one‑bud‑one‑leaf.
• Bud‑and‑leaf type: one‑bud‑one‑leaf up to newly unfurled one‑bud‑two‑leaf.
• Multi‑leaf type: shoots with one bud plus two or more leaves.
Dark tea generally demands high leaf maturity, mostly harvested as one‑bud‑three‑leaf / one‑bud‑four‑leaf, sometimes with stems attached. Still, plucking standards nowadays are also adjusted according to pricing tiers. For example, ancient‑tree raw Pu‑erh from Yunnan is frequently plucked at one‑bud‑two‑leaf.
Matcha raw material follows somewhat special rules. Machine‑harvest is carried out mainly at one‑bud‑three‑leaf to one‑bud‑four‑leaf. Even the very first spring flush must grow to this maturity before being gathered. This requirement comes from matcha's processing technology and flavour profile.
Younger plucking brings brighter, fresher flavour, as seen in pre‑Qingming Longjing. However, overly tender leaves lack body and depth. Pure bud‑only material, in particular, does not accumulate sufficient internal compounds. Tea made from very tender material also has limited storage potential. Pre‑Qingming Longjing, for example, loses much of its aroma and taste after one‑year storage.
Dark teas designed for post‑fermentation and long‑term ageing need abundant internal substances to support microbial transformation and slow maturation over years. Highly‑mature raw material is therefore essential. If overly tender leaves are used, polysaccharides and pectin will be insufficient. Microbes would consume most available substances during post‑fermentation; after several more years of ageing, barely any flavour‑giving compounds remain for infusion.
Tea can be likened to human beings. Tender buds resemble youth: bright, lively and spirited. Open‑face mature shoots stand for middle age: firm‑bodied, multi‑layered and well‑structured. Fully‑mature older leaves are like the elderly: gentle and mellow, shaped by time.
