{"type":"firestarter.listing","listing":{"id":"lst_hPG5bTIV","product_name":"White Koji Pu-erh","category":"Japanese Loose Leaf Tea","description":"\nA rare and unique opportunity to try a one-of-a-kind tea! Japan is not known for pu-erh, but there are a few tea producers who are starting to experiment with fermenting wakoucha (black tea) with koji-kin (asperillus oryzae mold spores). Koji is also used to make popular Japanese foods like soy sauce, miso, and sake. \nMizuba's pick is fermented with white koji ( Shirokoji 白麹), which is often used to brew shōchū and has a lighter taste than black koji. The fermentation gives rise to a rich, amber liquor with lush aromas of caramel, honey, and fruit. We love the complexity and refinement of this elegant and unusual tea! \n\n","images":["https://cdn.shopify.com/s/files/1/0332/2957/files/DSCF2832.jpg?v=1698270436","https://cdn.shopify.com/s/files/1/0332/2957/files/DSCF2825.jpg?v=1698270654","https://cdn.shopify.com/s/files/1/0332/2957/files/DSCF2894.jpg?v=1698270655","https://cdn.shopify.com/s/files/1/0332/2957/files/DSCF2910.jpg?v=1698270654","https://cdn.shopify.com/s/files/1/0332/2957/files/DSCF2926.jpg?v=1698270653"],"price":16,"currency":"USD","in_stock":true,"inventory_qty":19998,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:25.798Z"},"share_url":"https://firestarter.network/l/lst_hPG5bTIV","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
