云南白茶 (Yúnnán báichá); on a price list — 云南早春白茶 (Yúnnán zǎochūn báichá), "Yunnan early spring white."
a variety/style/region within the white tea category.
Pu'er (普洱, Pǔ'ěr), Lincang (临沧, Líncāng), Baoshan (保山, Bǎoshān), Xishuangbanna (西双版纳, Xīshuāngbǎnnà), Dehong (德宏, Déhóng).
large-leaf cultivars of Camellia sinensis var. assamica.
"Moonlight White" (月光白, Yuèguāng bái), sometimes encountered under the name "Moonlight Beauty" (月光美人, Yuèguāng měirén).
Origin: Yunnan Province (云南省, Yúnnán shěng), PRC.
Type: white tea (白茶, báichá), minimally processed (only withering and drying).
Facts
"Moonlight White" is associated with the two-tone color of the leaf — the dark upper side and the light downy underside resemble a lunar reflection; a poetic legend about night drying under the moon is also widespread, which belongs more to folklore than to technology.
from the Yangta cultivar, a bundled "White Dragon Whiskers" was made, supplied to the court in the Qing era.
due to the closeness of Yunnan white-tea and early pu-erh processing, some samples are classified either as white tea or as a special Yunnan group — this is one of the lively discussions in tea circles.
the same style is sometimes encountered under the name "Moonlight Beauty" (月光美人, Yuèguāng měirén).
History and Culture
the large-leaf white-leaf cultivar Yangta (秧塔大白茶, Yāngtǎ dàbáichá) from Yangta Village, Minle Town (民乐镇, Mínlè zhèn), Jinggu County.
"White Dragon Whiskers" (白龙须贡茶, Báilóngxū gòngchá), which was crafted from this raw material.
cultivation of Yangta is attributed to the reign under the Daoguang era (道光, Dàoguāng, 1821–1850) of the Qing Dynasty.
formation of the category and its branding — the 2000s.
Botany and Raw Material
Camellia sinensis var. assamica, a large-leaf variety.
Yangta Dabai (秧塔大白茶, Yāngtǎ dàbáichá), Jinggu Dabai (景谷大白茶, Jǐnggǔ dàbáichá), Mengku Large Leaf (勐库大叶种, Měngkù dàyèzhǒng), Fengqing Large Leaf (凤庆大叶种, Fèngqìng dàyèzhǒng), Menghai Large Leaf (勐海大叶种, Měnghǎi dàyèzhǒng).
buds and young leaves with dense white down (白毫, báiháo).
Picking: for top grades — early spring (早春, zǎochūn), while the leaf is tender and rich in down.
Terroir
Climate: subtropical monsoon, warm, humid, with frequent fogs and a large diurnal temperature range.
Soil: predominantly red soils and lateritic soils, rich in iron.
Yunnan, southwestern China, zone of origin of the tea plant.
typically around 1000–2200 m above sea level.
from ancient trees and old gardens to modern terrace plantations.
Production
withering (萎凋, wěidiāo) and drying (干燥, gānzào).
pan-frying/fixation (杀青, shāqīng) and rolling (揉捻, róuniǎn).
indoors, in the sun (日光萎凋, rìguāng wěidiāo), or combined.
loose tea or pressed cakes (饼, bǐng) and other forms.
Organoleptic Profile
two-tone leaf — dark on top and light, downy underneath; silvery buds.
honey, dried fruits, field flowers, notes of hay and freshly cut grass in young tea.
from pale golden in young tea to amber in aged.
sweet, lingering, with a soft returning sweetness in the throat.
Taste: sweet, rounded, fuller-bodied than Fujian white tea, with fruity nuances.
Chemical Composition
approximately 3–5%.
on the order of several percent; contribute sweetness and umami.
content characteristically increases with prolonged aging.
Polyphenols: in large-leaf varieties, approximately 25–35% of dry mass, higher than in small-leaf varieties.
Health Notes
linked to the polyphenols and flavonoids of the minimally processed leaf.
young white tea is considered "cooling" (凉性) in Chinese tradition, while aged is gentler on the stomach.
«一年茶,三年药,七年宝» (yī nián chá, sān nián yào, qī nián bǎo) — "one year — tea, three years — medicine, seven years — treasure."
Brewing
about 5 g per 100 ml.
90–95°C for typical large-leaf Yunnan white; 85–90°C for delicate bud versions; 95–100°C is acceptable for old tea.
an optional short rinsing infusion, then steeping from 10–20 seconds with gradual increase; withstands many infusions.
2–3 g per 200–250 ml, 85–90°C, 2–4 minutes.
aged white tea reveals itself well when boiled — bring to a boil and simmer for several minutes.
Teaware: porcelain or clay gaiwan (盖碗, gàiwǎn); glass is also suitable for young tea; a boiling kettle is convenient for aged tea.
Storage
a dry, cool, dark place free of foreign odors; low humidity.
for long-term aging — packaging that protects from light and odors but allows slow "breathing"; cakes and loose tea are stored differently.
under proper conditions, the tea ages for many years, gradually changing its profile toward dried fruits and honey.
Price and Authenticity
very wide — from inexpensive plantation "Moonlight White" to high prices for tea from ancient trees and for aged batches with transparent provenance.
age of bushes (ancient trees versus plantations), area, harvest year and aging duration, grade (proportion of buds).
