That export recipe became Guinness Extra Stout — dark as midnight, rich as caramel, and sturdy enough to carry the family name far beyond Dublin. To this day, the Extra Stout is the preferred Guinness brew in parts of Africa, Asia, and the Caribbean.\nMade from sturdy cotton twill with our signature green satin underbrim, this Guinness x Ebbets Field hat features a felt appliqué badge inspired by the vintage Extra Stout logo.","images":["https://cdn.shopify.com/s/files/1/1487/1618/files/20260216_EBBETS8467.jpg?v=1772135325","https://cdn.shopify.com/s/files/1/1487/1618/files/Ad_1_-_1080x1350_058bff34-8829-4e23-bda1-e83f5f430df6.png?v=1775850836","https://cdn.shopify.com/s/files/1/1487/1618/files/20260216_EBBETS8470.jpg?v=1775850836","https://cdn.shopify.com/s/files/1/1487/1618/files/20260216_EBBETS8469.jpg?v=1775850836","https://cdn.shopify.com/s/files/1/1487/1618/files/20260216_EBBETS8468.jpg?v=1775850836","https://cdn.shopify.com/s/files/1/1487/1618/files/20260216_EBBETS8466.jpg?v=1775850836"],"price":41,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:30:38.135Z"},"share_url":"https://firestarter.network/l/lst_9Uja9uVP","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
