{"type":"firestarter.listing","listing":{"id":"lst_olCcsn3o","product_name":"Single-Serve Coldbrew Original Matcha","category":null,"description":"Need a convenient way to make coldbrew matcha on the go?\nPerfect for travel -- they weigh almost nothing and take up almost no space. Many people keep them in purses, gymbags, carry-ons, even cars! Cyclists and fitness enthusiasts love them -- coldbrew is so much more satisfying than water when thirsty.\nEach packet contains 1.5 grams of Coldbrew Original, the perfect amount of matcha for an 8 to 12-oz serving (depending on how thick/thin you like it).\nSimply fill your water bottle, mason jar, or other clean jar with icy-cold water (with or without actual ice--just be sure the water is very cold), add the matcha, and shake hard for about 10 seconds. Microbubbles will begin to form and eventually create a gorgeous crema on top that resembles a Guinness draft!","images":["https://cdn.shopify.com/s/files/1/0222/8459/9373/products/BAM-SSCB-01.jpg?v=1575661899","https://cdn.shopify.com/s/files/1/0222/8459/9373/products/BAM-SSCB_03.jpg?v=1575665162","https://cdn.shopify.com/s/files/1/0222/8459/9373/products/CB-powder-01_copy.jpg?v=1575665265","https://cdn.shopify.com/s/files/1/0222/8459/9373/files/BAM-SS-10PK.jpg?v=1758157226"],"price":24,"currency":"USD","in_stock":true,"inventory_qty":29997,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:26.580Z"},"share_url":"https://firestarter.network/l/lst_olCcsn3o","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
