Nantou
Nantou is Taiwan's only landlocked county, it sits in the middle of the island's mountains and it grows more tea than anywhere else on it. It also holds both ends of the Taiwanese style at once: Lugu, where Dong Ding established the roasted tradition, and the high gardens at Shanlinxi that belong to the modern green, unroasted school. The bulk tea that fills the island's drinks shops comes from here too.
What grows here
Dong Ding from Lugu is the county's classic, a rolled oolong defined by its roast rather than its altitude. Shanlinxi, in Zhushan, is the high mountain counterpart, and the Yushan gardens in Xinyi and the Ren'ai high ground add more alpine plantings. Mingjian, at the low end, is the volume township: machine-picked Si Ji Chun and Jin Xuan that supply the domestic drinks trade. Yuchi, on Sun Moon Lake, is where Taiwan's black tea is made, including the Ruby cultivar.
The ground
The county climbs from a few hundred metres at Mingjian to well above 1,500 m at Shanlinxi and higher again toward Yushan, so it contains most of Taiwan's altitude range in one administrative unit. The high gardens get the cloud cover, cold nights and slow growth that high mountain oolong is sold on. Sun Moon Lake sits in a mid-altitude basin where the water body itself moderates the temperature and keeps the humidity up, which is part of why a black tea works there.
The bushes
Qing Xin carries the reputation, both for Dong Ding and for the high mountain gardens, low-yielding and demanding as always. Mingjian's economics push the other way, toward Si Ji Chun and Jin Xuan, which flush hard and take machine picking. Yuchi is different again: Assam-type material introduced under Japanese rule, plus Taiwan No. 18 Ruby, a cross of Burmese assamica with native Taiwanese wild tea that gives the mint-and-cinnamon aroma the lake is known for.
Harvest seasons
Spring and winter carry the mountain teas, as they do across Taiwan, with winter lots picked late in the year prized for tightness and fragrance. Mingjian's low ground works to a completely different rhythm and can be picked many times a year, mechanically, which is exactly the point of it. Sun Moon Lake's black tea takes its best material in summer, when heat and rain suit the assamica bushes and would spoil an oolong.
How it is made here
Dong Ding is where Taiwanese roasting is defined. Traditionally it is taken to a moderate oxidation and then baked, sometimes repeatedly over long periods, which is what gives the caramel and toasted-grain depth that the greener high mountain style deliberately leaves out. Shanlinxi is made the modern way, rolled tight and barely roasted at all. The Lugu farmers' association competition, one of the largest tea contests anywhere by number of entries, judges the roasted style and effectively sets the local standard.
What to look for
Dong Ding has become a processing style more than a place: the actual Dong Ding mountain plots are small, and a great deal of tea grown elsewhere is roasted to that profile and sold under the name. Ask where the leaf grew before you ask about the roast. Competition-ranked teas carry real information, since the judging is serious, but also carry a substantial multiple. And treat Mingjian tea as what it is, competent bulk material, rather than as a cheap high mountain oolong.
How it got here
The local account traces Dong Ding to cuttings carried back from Fujian in the nineteenth century, and Lugu has traded on that origin ever since. Sun Moon Lake's black tea is a colonial-era project: the Japanese administration brought Assam seed to Yuchi in the 1920s and later set up a research station to work with it, and the modern Ruby cultivar descends from that programme. The 1999 earthquake, centred in the county, damaged the gardens and the roads to them, and the Taiwanese trade traces Gui Fei to the aftermath, when Lugu growers busy rebuilding left their plots to the leafhoppers and roasted the bitten leaf rather than write it off.
