High-mountain tea
varieties of oolong tea grown in Taiwan
High-mountain tea or gaoshan tea (Chinese: 高山茶; pinyin: gāoshān chá; pronounced [káʊ.ʂán ʈʂʰǎ]) refers to several varieties of Oolong tea grown in the mountains of central Taiwan. It is grown at altitudes higher than 1,000 metres (3,300 ft) above sea level, and includes varieties such as Alishan, Dayuling, Yu Shan, Wushe, and Lishan. The high humidity and natural precipitation in the high mountain ranges of Nantou and Chiayi Counties make the region a suitable environment for growing tea plants. High Mountain green teas can be characterized as tender, green, and sweet, with certain production processes also revealing notes of chestnut. Generally, high mountain teas are high sweet, high fresh, and low bitterness, making it more appealing to consumers. The fermentation process that removes the harsh ingredients allows the tea to taste flavorful.
Production
Gaoshan tea leaves are usually hand harvested, and grow slowly due to the thin air in high altitudes. Hence, the yield of gaoshan tea is relatively low every year. There are two kinds of gaoshan tea based on the season: winter gaoshan is harvested during late October, and spring gaoshan is harvested during the middle of June.
It takes about 36 to 40 hours to process a batch of gaoshan tea.

Why this record matters
The subject matters to the general reference register because the source frames it as varieties of oolong tea grown in Taiwan. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
