{"type":"firestarter.listing","listing":{"id":"lst_RWLtD3fq","product_name":"Merlot Lettuce","category":"Vegetables","description":"Looking for that perfect lettuce to complement a rich autumn feast? In Merlot, you'll find deep garnet hues with a brilliant sparkle. The rich, earthy flavor belies a distinct nose of black cherry with herbaceous undertones. Fresh and full-bodied and cloaked in a subtle, ruffled velvet robe, Merlot's mouth feel delights. It is well structured, supple, and smooth. A deep purple beauty, this recent vintage is sure to please the whole table. (Note: unlike other merlots, this one does not improve with age; harvest young!)","images":["https://cdn.shopify.com/s/files/1/0072/0909/1117/files/merlot_2.png?v=1751916763","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Merlot-Lettuce-vendor-unknown-1630677985.jpg?v=1751916763","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/merlot.png?v=1751916763","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/merlot-lettuce.jpg?v=1782417228","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/IMG_3830.jpg?v=1751916763","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/merlot_3.png?v=1751916763","https://cdn.shopify.com/s/files/1/0072/0909/1117/products/Merlot-Lettuce-vendor-unknown-1630677982.jpg?v=1751916763","https://cdn.shopify.com/s/files/1/0072/0909/1117/files/merlot-lettuce1.jpg?v=1782417231"],"price":4.99,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:38.852Z"},"share_url":"https://firestarter.network/l/lst_RWLtD3fq","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
