Gaba Oolong (佳葉龍茶)
archetype: Bear in winter's den
This tea is like a bear that has settled into its winter den: the fire in it does not dance — it smolders in the embers. It does not lead you by the hand; it lies down beside you and breathes with you, until the anxiety burns down to warm ash.
History
The GABA process was discovered by chance by Japanese scientists in 1984: searching for a way to extend the life of tea leaf, they sealed it in an oxygen-free environment — and found that levels of gamma-aminobutyric acid rose sharply. Taiwan applied the method to a classic oolong: the leaf is rolled like Dong Ding, oxidised to 25–35%, roasted, and then sealed for 8–10 hours in a vessel of nitrogen. The fire in this tea does not leave — it curls up like a bear and falls asleep inside the leaf.
Terroir
The high-mountain gardens of Lugu and Dong Ding give the optimal leaf — dense, oily, with a long aftertaste.
Leaf
dense, oily, with a long finish; the first infusions give honey and date, the middle ones baked apple and wood, the late ones warm earth and a faint smoke very long, calming, felt in the chest and the belly
Properties
GABA (γ-aminobutyric acid) content from 150 mg/100 g and higher; gently lowers anxiety, supports sleep, does not 'hit' the nervous system the way an ordinary oolong does thick, warm, settling in the chest and shoulders; the body grows heavy, the breath slows down moderate (40–60 mg per cup), but the effect is soft thanks to the GABA
Brewing ritual
a 110 ml gaiwan or a yixing pot of hunni clay (warm earth); soft water, 95 °C; 6 g / 110 ml. 15s — first warmth — honey and date, the leaf is only just waking; 12s — the peak of density: molasses, baked apple, warm wood; 18s — the den: fur of dry grass, cinnamon, a faint sootiness; 25s — the fire settles into the earth — stewed pear, vanilla, silt; 35s — a long warm note, a slow sunset; 50s — warm ash, wood, an aftertaste that holds for an hour.
When to drink
after sunset, ideally about an hour before sleep. late autumn and winter, especially on cold dark days. when sleep won't come because of stray thoughts; when the body is tired but the head keeps running in circles
