{"type":"firestarter.listing","listing":{"id":"lst_fIjrlAnu","product_name":"Oolong","category":"Oolong Tea","description":"The tea that sits between green and black.\nTi Kuan Yin is a semi-oxidized oolong from Fujian Province, China. The leaf is 40-50% oxidized, which puts it halfway between the vegetal brightness of green tea and the malty body of black tea. The cup tastes like blooming orchids over toasted walnuts, with a buttery texture that lingers. The process is what makes it: the leaves are bruised in bamboo baskets to start oxidation at the edges, then fired to stop the reaction. The bruising is what releases the floral compounds.\n\nWhy the leaves are twisted.\nTi Kuan Yin is rolled into tight pellets during production. The rolling breaks down cell walls and compresses the leaf, which concentrates the aromatic oils. When you steep the leaf, it unfurls slowly, releasing flavor in stages. This is why oolong re-steeps so well. The first steep opens the leaf. The second and third steeps extract the deeper notes. By the fourth steep, the leaf is fully open and the cup is softer, sweeter, with almost no astringency.\n\nThe Hui Gan phenomenon.\nChinese tea tradition names the returning sweetness that shows up after you swallow. Hui Gan translates as \"returning sweetness.\" High-quality oolongs produce it reliably. The sweetness sits at the back of the throat and builds with each sip. The effect is subtle, but once you notice it, you notice it every time. Floral, toasted, sweet on the return.","images":["https://cdn.shopify.com/s/files/1/0806/0862/4962/files/oolong-loose-tea-ybtco.webp?v=1779851321","https://cdn.shopify.com/s/files/1/0806/0862/4962/files/oolong-brewed-tea-ybtco.webp?v=1779851320","https://cdn.shopify.com/s/files/1/0806/0862/4962/files/oolong-tin-tea-ybtco.webp?v=1779851317"],"price":18,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:17.032Z"},"share_url":"https://firestarter.network/l/lst_fIjrlAnu","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
