Fraction is carefully blended with an equal balance of caffeinated and decaffeinated coffee from South or Central America depending on the season. This half-caff coffee blend is ideal for just one more mid-afternoon cup or a post-dinner desert counterpart, the preamble to decaf. Look for notes of deep chocolate and cherry in this balanced cup.","images":["https://cdn.shopify.com/s/files/1/0693/8781/3104/files/Fraction_8oz_PDP_00aeddad-112e-4980-9456-dd69114d8d5c.jpg?v=1770134519","https://cdn.shopify.com/s/files/1/0693/8781/3104/files/Fraction-Coffee_Info_Card_Website_171f139f-fc7e-4105-a989-7c8e9b0d374f.jpg?v=1770134519"],"price":13,"currency":"USD","in_stock":true,"inventory_qty":39996,"dynamic_pricing":false,"listed_at":"2026-06-18T20:46:13.578Z"},"share_url":"https://firestarter.network/l/lst_owxeNPZM","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
