About Nonesuch Oysters

Harvest location: Scarborough, ME

How they’re grown: Emeralds are the Nonesuch bottom cultured oysters and the entire lease is sub-tidal. They’re spread across the bed of the river and harvested by a small drag, either with a rake or everyone’s favorite technique...swimming with a snorkel! The oysters are placed in crates for a week on the surface to purge any extra sand or silt. This extra step ensures that the shells are squeaky clean, inside and out!

Why they’re unique: 
Emeralds are named for the distinctive green hue given to them by a specific benthic algae that only exists in areas of very high water quality. The Scarborough River boasts a Grade A water classification due to its "outstanding natural resource waters", which is why Nonesuch has such great-tasting, healthy oysters!

Maine native Abigail Carroll describes her entrance to the oyster trade as accidental. She lived in Paris for several years, trading stocks, consulting on business plans, dating a French Count, and living what she describes as a ‘clean and easy life’. After returning home to Maine, she agreed to help a friend write a business plan for an oyster farm with the caveat that she would NOT be getting her hands dirty--famous last words, as they say. After the business plans went awry, Abigail ended up owning the property, and much to her own surprise, she ‘cowboyed up’, bought a pair of waders, and started farming oysters. In 2021, Abigail passed the farm on to current owner, Ryan McPherson, who has big plans for the future of the farm.

Oyster FAQ

How long do my oysters keep?

Your oysters keep in the refrigerator for 5-7 days!  You can order a day or two early to make sure you have them in time for your gathering.  They are totally fine hangin’ out in the cool air.  

How do I store these bad boys?

When you receive your package, pull them out of the box (these guys need a little fresh air!). Grab a mixing bowl and throw the mesh bag in the bowl so that the oysters don’t leak all over your refrigerator. Grab a damp cloth and throw the cloth over the bowl.  You are good to go for the next 5-7 days. Doesn’t hurt to dampen the cloth each day to keep them moist and chilled.

Should I keep them on ice?

Only put the oysters on ice before service.  The oysters will actually die in the melted fresh water so do not store the oysters on ice.  They will not like this.

How are they shipped?

We ship using FedEx Overnight service. You will receive tracking info after the label has been printed the day before your oysters are set to arrive.  We do not require a signature – Fedex will leave your package at your doorstep.

Is your packaging recyclable?
