Yunnan large-leaf variety (云南大叶种, Yúnnán dàyèzhǒng), botanically — Camellia sinensis var. assamica.

Origin: Yunnan Province (云南, Yúnnán), southwest China; historical birthplace — Fengqing County (凤庆县, Fèngqìng xiàn) in Lincang Prefecture-level City (临沧, Líncāng).

Type: red tea (红茶, hóngchá), fully fermented (oxidized).

Facts

the abbreviation "滇" (Diān) traces back to the ancient Dian Kingdom and the eponymous lake near modern Kunming; over time, the character came to denote all of Yunnan.

unlike many ancient Chinese teas, Dian Hong is less than a century old.

red Dian Hong and the renowned pu'er are made from the same large-leaf variety but by different technologies.

from its inception, Dian Hong was oriented toward the external market and is still widely represented in global trade.

History and Culture

Cultural Significance: a symbol of Yunnan's tea exports; Fengqing bears the unofficial title "home of Dian Hong" (滇红之乡, Diān hóng zhī xiāng).

1938–1939.

Feng Shaoqiu (冯绍裘, Féng Shàoqiú), specialist-technologist.

Shunning (顺宁, Shùnníng) — the former (before 1954) name of Fengqing County.

"Fengqing Dian Hong" (凤庆滇红茶, Fèngqìng Diān hóng chá) is protected as a geographical indication product.

Botany and Raw Material

Fengqing large-leaf (凤庆大叶种, Fèngqìng dàyèzhǒng), Mengku large-leaf (勐库大叶种, Měngkù dàyèzhǒng), Menghai large-leaf (勐海大叶种, Měnghǎi dàyèzhǒng).

traditional seed-propagated populations (群体种, qúntǐzhǒng), including those from aged trees.

Cultivar: Camellia sinensis var. assamica — Yunnan large-leaf variety (云南大叶种, Yúnnán dàyèzhǒng).

Terroir

Climate: subtropical monsoon, warm and humid, with distinct dry and rainy seasons.

Soil: red earths and lateritic soils, rich in iron.

Fengqing (凤庆, Fèngqìng), Yunxian (云县, Yúnxiàn), Shuangjiang (双江, Shuāngjiāng), Mengku (勐库, Měngkù).

Topography: mountainous areas at altitudes roughly from 1000 to 2000 m and above sea level.

Production

fresh leaves lose part of their moisture and become pliable.

cell walls are ruptured, juices are released, and oxidation is initiated.

essentially enzymatic oxidation in a warm and humid environment, forming the red infusion and characteristic aroma.

usually by hot air; stops oxidation and fixes the flavor.

Organoleptic Profile

tightly twisted leaves of a reddish-brown color, often with an abundance of golden tips (金毫, jīn háo).

transparent, red-orange, with a golden ring along the edge of the cup.

honeyed and malty, with notes of dried fruit (longan), sometimes floral or cocoa notes.

rich, sweetish, smooth, with moderate astringency and a long aftertaste.

copper-red, soft, even.

Chemical Composition

in fresh large-leaf raw material, their content is high and can reach 30% or more.

responsible for the brightness and "liveliness" of the infusion.

form the red color and fullness of body.

provide depth of hue.

content is elevated, generally higher than in small-leaf varieties.

contribute to the formation of sweetness and smoothness.

Health Notes

in Chinese tradition, red tea is considered "warm" (温, wēn), suitable for the cold season.

aids digestion, pairs well with rich or fatty foods.

theaflavins and other polyphenols possess antioxidant activity.

caffeine exerts a gentle tonic effect.

Brewing

about 4–5 g per 100 ml for gongfu-style steeping; 3–4 g per 300 ml for simple brewing.

90–95 °C. Excessively boiling water intensifies astringency and mutes sweetness, so the water should be allowed to cool slightly.

rinse the leaf with a short first infusion, then brew with short steeping times (first infusions 5–10 seconds, subsequently increasing). Quality leaf-style Dian Hong can yield 6–10 infusions.

Teaware: gaiwan or a small teapot (porcelain, less often Yixing clay) with a volume of 100–150 ml.

Storage

Shelf Life: red tea is best consumed fresh, within 1–2 years; it is not intended for long-term aging like pu'er.

airtight, opaque packaging, away from light, moisture, heat, and foreign odors.

tin canisters, foil-lined bags; do not store near spices or coffee.

Price and Authenticity

very broad. Mass-market broken tea is inexpensive; mid-range leaf-style gongfu is moderate; bud-heavy grades and tea from old seed-propagated plantings and aged trees are noticeably more expensive.

Price Factors: type of raw material and bush variety, season (spring is valued higher), proportion of buds and golden tips, region, and age of trees.
