Mingqian Huangjin Ya from Zhejiang 浙江明前黄金芽浙江明前黄金芽

Classification and Origin

Mingqian huangjin ya from Zhejiang (literally "golden bud before Qingming").

before Qingming, early April (明前).

huangjin ya (黄金芽, huángjīn yá) — light-sensitive yellow-leaf cultivar (光照敏感型, guāngzhào mǐngǎn xíng).

most often green tea (绿茶, lǜchá); more rarely — using yellow tea technology (黄茶, huángchá) with a yellowing stage.

Origin: Zhejiang province, mainly the Yuyao area (余姚, Yúyáo) in the Ningbo urban district (宁波, Níngbō).

Facts

huangjin ya yellows from the sun and stays golden year-round, whereas Anji baicha pales only in the early cool spring and then turns green.

this is one of the few cultivars with a stably golden leaf, rather than one that lightens seasonally.

low chlorophyll means weak photosynthesis, slow growth and low yield — hence the high price.

huangjin ya belongs to the group of cultivars with disrupted chlorophyll synthesis, which is actively studied and bred in Zhejiang.

History and Culture

late 20th – early 21st century, Zhejiang.

its origin is connected with the Yuyao area (余姚) near Ningbo.

selection of a natural mutation and vegetative propagation.

Botany and Raw Material

light-sensitive albinism (白化, báihuà) — yellow coloration is maintained year-round and intensifies in sunlight.

single bud or bud with one leaf, even and tender.

Cultivar: huangjin ya (黄金芽), shrub form, leaf from small to medium.

Terroir

Climate: subtropical monsoon, warm and humid, with fog in the foothills.

Soil: acidic, loose, well-drained.

Zhejiang.

Yuyao and the Siming foothills (四明山, Sìmíng shān); the cultivar has spread to other counties of Zhejiang as well as beyond the province.

Production

early spring morning, by hand, only tender buds.

in a thin layer for even loss of part of the moisture.

heating that halts enzyme activity and fixes the colour.

light, so as not to destroy the tender buds and to preserve shape.

bringing to a stable low moisture content.

Organoleptic Profile

bright golden-yellow, even tender buds.

transparent, light, yellow-green or golden.

fresh, delicate, with green-herbaceous and light floral notes.

soft, even, bright yellow in colour.

Taste: very fresh, sweetish, with pronounced umami, minimal bitterness and astringency.

Chemical Composition

Amino Acids: very high content; according to a number of measurements noticeably higher than ordinary green teas (which are in the range of about 2–4%), in the best spring batches — approximately up to 6% or more.

one of the main amino acids, responsible for sweetness and umami.

relatively moderate, hence the low bitterness.

reduced — this is what yields the yellow coloration.

present within the usual limits for tea.

Health Notes

promotes calm concentration and gently balances the stimulating action of caffeine.

polyphenols and catechins possess antioxidant activity.

low astringency makes the beverage comfortable for many people.

Brewing

about 3 g per 150 ml (in a gaiwan slightly more is possible).

soft, with low mineralisation.

Teaware: a glass cup (玻璃杯, bōlibēi) — to admire the golden buds; or a porcelain gaiwan (盖碗, gàiwǎn).

Water Temperature: 80–85 °C; tender buds dislike rolling-boil water.

Storage

Container: airtight packaging; for long-term storage a fridge or freezer compartment is convenient.

Shelf Life: drink fresh, ideally within a year of harvest.

as for green tea — cool, dark, absence of air access and foreign odours.

Price and Authenticity

high; huangjin ya is one of the most expensive cultivars due to low yield and early harvest.

mingqian harvest, a high proportion of whole buds, purity of origin.
