{"type":"firestarter.listing","listing":{"id":"lst_hzXfUQvp","product_name":"Koshun Matcha Green Tea","category":"Matcha Green Tea","description":"An exquisite and rare selection from Tenryu, Shizuoka. We love featuring Koshun for its herbal and fruity aroma and playfulness on the palate. Our particular Koshun matcha is grown at a high altitude of 600m above sea level (testing the limits of where tea can be produced), resulting in a rich, deep flavor. \nOur producer notes that the tea pairs deliciously with a touch of milk, making a luxurious latte.","images":["https://cdn.shopify.com/s/files/1/0332/2957/files/Koshun.png?v=1746115296","https://cdn.shopify.com/s/files/1/0332/2957/files/DSCF6554-2.png?v=1746115330","https://cdn.shopify.com/s/files/1/0332/2957/files/DSCF6563-2.png?v=1746115330","https://cdn.shopify.com/s/files/1/0332/2957/files/Koshun-green-tea.webp?v=1746463516"],"price":42,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:25.736Z"},"share_url":"https://firestarter.network/l/lst_hzXfUQvp","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
