Boseong
Boseong is the photograph Korea uses to advertise tea: contour terraces stacked up low hillsides, cedar avenues, a winter light festival. It is also the industrial half of the Korean industry and the deliberate opposite of Hadong, laid out as a plantation in the twentieth century, planted with clonal material rather than seed and worked with machines wherever the ground allows. Most Koreans meet Korean tea through Boseong, in a bag or a bottle or a food product, rather than through a small maker's spring picking.
What grows here
Green tea in the four picking-date grades, ujeon through daejak, with the later machine-cut grades making up far more of the volume than they do inland. A good part of the crop never reaches a teapot as loose leaf: it goes into teabags, bottled drinks, powdered tea and the green tea food products the county sells to its own visitors. Balhyocha is made by some producers, but it belongs to Hadong rather than here.
The ground
Low coastal hills in South Jeolla, a few kilometres from the southern sea, with sea fog moving over the gardens and winters mild enough that cold damage is less of a constraint than in the mountain districts. The slopes are gentle enough to terrace on the contour, which is why Boseong looks the way it does and Hadong does not: the shape of the famous hillsides is a farming decision about machine access and drainage before it is scenery. Growers credit the fog and the maritime air for a softer, less astringent leaf.
The bushes
Mostly clonal, and much of the planting stock is Japanese in origin, Yabukita included, because that material and the people who knew how to work it were what was available when the estates were laid out. This is the sharpest difference from Hadong's seed-grown jaeraejong, and it carries into the cup: a Boseong green can read as a close relative of a Japanese tea, especially in the steamed lots, where a Hadong tea usually does not.
Harvest seasons
The same four grades as the rest of the country, but the mild coast opens a little earlier and runs later than the mountain valleys. The consequence is volume. Boseong can take a large daejak crop that Hadong cannot, and that later, coarser, usually machine-cut leaf is what feeds the bagged and bottled trade. Ujeon and sejak here are the small end of a big operation rather than the whole business.
How it is made here
Two lines running side by side. The traditional Korean pan-firing and hand-rolling continues at the smaller farms, while the large factories steam the leaf to fix it instead, on equipment built to Japanese patterns, and Boseong is where most Korean steamed green tea comes from. Those factories also make cut and powdered grades that the mountain districts do not attempt. If you want to know what a tea will taste like before you buy it, ask whether it was pan-fired or steamed: here that decides more than the grade name does.
What to look for
Boseong is a place brand before it is a leaf, and much of what carries the name is ordinary tea sold to visitors. The terraced hillside in every photograph is one private farm, Daehan Dawon, not the county. Boseong green tea was Korea's first registered geographical indication, granted in 2002, so the name is regulated, but the range inside it is enormous: the same three syllables cover careful hand-made spring lots and bulk material destined for bottling. The grade name will not separate those two; asking who made it and how will.
How it got here
The first large modern plantation in Korea was laid out here in 1939, under Japanese rule, on ground chosen for an industry rather than around a temple. It was abandoned when the Japanese left in 1945 and lay neglected until a Korean buyer restored it in 1957 as Daehan Dawon, which is when the terraces and the cedar avenues that define the place were made. Tourism arrived later and now shapes the county as much as tea does. The fields are a destination with a festival calendar attached, and the local economy runs on visitors and processed products as much as on loose leaf.
