Hadong
Hadong claims the oldest tea in Korea, planted on the flanks of Jirisan in the ninth century, and its gardens still look unlike a modern tea district: bushes scattered among rocks and trees up a river valley, seed-grown rather than cloned, unterraced and picked by hand because a machine could not get at them. The FAO listed the Hwagae valley's version of it as a globally important agricultural heritage system in 2017.
What grows here
Green tea in the four Korean picking-date grades, ujeon through daejak, is the bulk of it and the reason the valley is famous. Alongside it, producers make balhyocha, a partly oxidised tea with no clean equivalent in the Chinese or Japanese systems, called jaksal here after the local word for the leaf. Every maker oxidises it to a different degree, so it is less a style than a house habit. Production is atomised across many small makers and temples rather than concentrated in estates.
The ground
The gardens run up the Hwagae valley on the southern side of Jirisan, steep and rocky, with fog off the Seomjin river and cold nights that hold the season back. The bushes grow in and around forest rather than in cleared rows, so light is uneven and yields are low. That is the whole basis of Hadong's claim: the arrangement is inefficient in a way that shows up in the cup, and it is inefficient because nobody ever industrialised it.
The bushes
Jaeraejong, the native seed-grown population, which means every bush is genetically its own and the gardens are mixtures rather than plantings of a variety. This is the main thing separating Hadong from Boseong and Jeju, where clonal material, much of it Japanese in origin, was planted when those estates were laid out, and it is why Hadong tea tends to taste less like a Japanese green than other Korean tea does.
Harvest seasons
The ujeon window, before Gogu around 20 April, is short here and shorter than the national picture suggests, because the valley is cold and the bushes are high and shaded. Sejak follows, running to Ipha around 5 May, then jungjak later in the month. Everything is picked by hand, bush by bush, which is the real cost driver and the reason Hadong tea is expensive relative to the volume in the bag.
How it is made here
Pan-firing in a cauldron and hand-rolling on a mat, in alternating rounds, in the Korean manner, aiming for a soft, rounded, low-astringency cup rather than a crisp one. The scale is the notable part: much of this is made by individual producers and temple workshops in small batches, so the maker is a bigger variable than the village, and two teas from the same valley in the same week can differ considerably.
What to look for
Wild tea is the local marketing word and it usually means seed-grown and unterraced rather than genuinely uncultivated, which is a real distinction and worth understanding rather than dismissing. Buy on the maker's name, since production is small and uneven. And treat the grade names as picking dates: a carefully made jungjak from a good producer will beat a mediocre ujeon that is trading on the word.
How it got here
The standard account has the envoy Kim Daeryeom returning from Tang China in 828 with seed that King Heungdeok ordered planted on these slopes, and the gardens around Ssanggyesa growing up under the monk Jingam in the decades after. Which temple on Jirisan was genuinely first is still disputed, but Hadong's claim rests on that story. Tea culture here survived the Joseon contraction largely through those temples, at a fraction of its former scale, and the modern industry was rebuilt in the second half of the twentieth century. The 2017 heritage designation formalised what the valley had been selling informally for years: continuity of method rather than scale.
