Expert Notes
Dukes of Topsail Sound are grown by Conor and Alyssa MacNair of N. Sea Oyster Co., who started the farm in 2017 just south of Topsail Island, North Carolina. The lease sits along the Intracoastal Waterway behind the undeveloped Lea-Hutaff Island, two miles from New Topsail Inlet, and the farm reports salinity of 32 to 33 parts per thousand, close to open ocean. The oysters are worked on a long-line system and tumbled on a strict schedule, with help from tide and chop, and are sold at about two years old. The farm describes open-ocean salt first and then a strong sweetness close to scallop, which it credits to the large adductor muscle the tumbling builds. Garden & Gun's panel called them rich, with a strong buttery brininess, and one chef tasted pine needles; Chubby Fish in Charleston prints spring onion and green garlic. In winter the gills can turn jade green when algae bloom. Origin & Characteristics

About the Farm
N. Sea Oyster Co.
Est. 2017Conor MacNair is a nephew of John Finger, the founder of Hog Island Oyster Company in California, who gave him his first oyster at about nine. He and Alyssa MacNair studied at the University of North Carolina Wilmington and started the farm in 2017, as the state was opening up shellfish leases. Their base, The Oyster Barn in Hampstead, has an oyster bar open on weekends. They occasionally harvest a second oyster, the green-gilled Divine Pines.
- Cultivation Method
- long-line system, tumbled on a set schedule
History & Background
The farm says its lease is two miles from New Topsail Inlet, that the oysters are two years old at sale and that salinity averages 32 to 33 parts per thousand. The Local Palate places the lease along the Intracoastal Waterway behind Lea-Hutaff Island. The farm's page lists Dukes as available from early spring to late fall, while a Chef Magazine line it quotes says year-round and The Local Palate says most of the year; we follow the farm.
Garden & Gun's 2021 guide to Southern oysters quoted Bryan Rackley of Watchman's in Atlanta calling them arguably the best oyster in the South. Chubby Fish in Charleston lists them as Dukes.
