Qilaishan 奇萊山奇莱山茶

Classification and Origin

high-mountain tea (高山茶, gāoshān chá), ball-rolled into tight pellets.

border zone of Hualien County (花蓮縣, Huālián Xiàn) and Nantou County (南投縣, Nántóu Xiàn); commercial gardens are concentrated primarily on the Nantou side, in the highlands of Ren'ai Township (仁愛鄉, Rén'ài Xiāng).

low, approximately 15–30%.

most often minimal or absent; lightly roasted versions are also encountered.

Origin: Qilai mountain massif (奇萊山, Qílái Shān; traditional spelling 奇萊山), Central Mountain Range (中央山脈, Zhōngyāng Shānmài), Taiwan.

Type: oolong (烏龍茶, wūlóng chá) — semi-fermented (partially oxidized) tea.

Facts

Qilai Peak is among Taiwan's famous high-mountain summits (百岳, bǎiyuè), popular with mountaineers.

the massif is known as "Black Qilai" (黑色奇萊, Hēisè Qílái) — a nickname linked to its ominous appearance in bad weather and its dangerous reputation for climbing.

the region adjoins other renowned high-mountain tea zones of central Taiwan, which often leads to confusion in names among buyers.

"Qilaishan" on the label indicates a locality, not a strictly certified origin from a specific garden.

History and Culture

Taiwanese oolong production took shape in the 19th century (Dongding area and foothills), while the high-mountain direction is a phenomenon of the second half of the 20th century.

mass establishment of gardens at elevations above 1000–2000 m began in the 1970s–1980s, driven by demand for "mountain" tea.

the development of tea cultivation in the central highlands was facilitated by the construction of mountain roads linking the interior ranges with the plains.

Botany and Raw Material

Qingxin Oolong (青心烏龍, qīngxīn wūlóng) — the classic cultivar of Taiwanese high-mountain oolong, with small, neat leaves and pronounced aromatic character.

Jinxuan (金萱, Jīnxuān; also known as 台茶12號, Táichá shí'èr hào / TTES No. 12) — with a more pronounced milky-creamy note, though less frequently found at the highest elevations.

hand-picked, a flush of a bud and two to three leaves; mature but not coarse leaves are valued.

the most prestigious are the spring (春茶, chūn chá) and winter (冬茶, dōng chá) harvests; the cold climate limits the number of harvests per year.

Terroir

Climate: large diurnal temperature variation, frequent fog and cloud cover, diffused light.

Soil: well-drained mountain soils on steep slopes.

the high-mountain gardens of the region are generally located well above 1000 m; for teas sold under the name Qilaishan, altitudes of around 2000 m and above are typical.

short growing season, slow shoot development.

Production

hand-picking of flushes in favorable weather.

withering of the leaf under diffused sunlight to lose some moisture.

alternating rest and light mechanical action on the leaf edges, initiating controlled oxidation and aroma formation.

heating to halt oxidation and set the profile.

initial deformation of the leaf.

repeated wrapping in cloth and compacting, giving the tea a tight pellet-like form.

bringing to stable moisture content.

optional; to preserve the fresh floral note, it is often minimal or absent.

Organoleptic Profile

tight dark-green pellets with a matte sheen; when unfurling — whole, elastic, light-green leaves.

from pale golden to greenish-yellow, transparent.

floral (orchid, lily), fresh, with milky-creamy and honeyed nuances.

long, with a sweet return (回甘, huígān) and a throat sensation (喉韻, hóuyùn).

Taste: sweet, smooth, dense, with minimal astringency and an "oily" texture.

Chemical Composition

Amino Acids: characteristically elevated content for high-mountain raw material, attributed to the cold climate and slow growth; these provide sweetness and softness.

present in moderate amounts; with low oxidation, some catechins are retained.

present in moderate amounts, as in all oolongs.

a rich complex of volatile substances forming the floral-creamy profile.

Health Notes

tea polyphenols possess antioxidant activity.

moderate caffeine combined with theanine yields a calm tonic effect.

oolongs are traditionally drunk after meals as a tea agreeable to digestion.

Brewing

approximately 5–7 g per 100–150 ml; the pellets expand noticeably in volume when unfurling.

soft, temperature 90–100 °C — high-mountain oolong reveals itself well with near-boiling water.

a short rinse of 3–5 seconds, optional, to "awaken" the rolled leaf.

infusion by infusion with gradual lengthening — the first around 20–40 seconds, then adding a few seconds each time.

quality leaf withstands 6–8 or more infusions, unfolding gradually.

Teaware: gaiwan (蓋碗, gàiwǎn) or a small teapot (porcelain or non-porous clay).

Storage

Shelf Life: lightly oxidized, unroasted Qilaishan is best drunk relatively fresh (within approximately one to two years), while the floral freshness is preserved.

airtight packaging, coolness, darkness, absence of foreign odors and moisture.

vacuum packaging is typical; an opened pack should be stored sealed, away from spices, coffee, and perfumes.

tolerate longer storage and can develop over time.

Price and Authenticity

Taiwanese high-mountain oolongs belong to the premium segment due to limited areas, manual labor, and logistics.

Qilaishan is usually less expensive than top Dayuling and Lishan but remains more costly than lowland and mid-mountain oolongs.

lowland or mid-mountain tea sold under a "high-mountain" name.

Vietnamese or other oolong passed off as Taiwanese high-mountain.
