Featured Farm: Butterfields -- June 2026
What’s happening in June on an oyster farm in Maine? Well, where do we begin? A little bit of everything. Waters are transforming to that nutrient-rich summer emerald; seed is growing in upwellers & nurseries; shells are sharp with feathery new edge. Seasonally we—oyster farms—are flowing (like our tides) into full swing. Butterfield Shellfish is no exception.
Located in Casco Bay off the coast of Yarmouth (between Little Moshier and Moshier Island, to be precise), the Butterfield lease sites combine a clear, marine waterway abundant in sea grasses with the nearby textures of protected coastline for a balanced merroir. As the first FlipFarm in the US, Butterfield carves out a unique spot among Maine sea farms, experimenting & adapting the trademark farming system to our shared waters. To learn more about FlipFarm, we would point you to the experts. But here’s the key idea: Growing oysters in surface or suspended gear requires a process called flipping, historically (& currently) performed by hand, by individual farmers. No frills in the name, flipping describes rotating all surface gear—bags, cages, or other kinds of baskets—so that the exposed side is submerged and vice versa. Why flip? Without flipping, gear can build up algae and other marine organisms that weigh them down, block critical water flow (which oysters need to feed), and make navigating & handling much more complicated. Once flipped, the sun steps in, burning off the ‘biofouling’ before the cycle continues. In a sense, flipping gear is like the oyster farmer’s equivalent to weeding. For most styles of surface or suspended gear, flipping requires human touch on each bag or cage, a laborious and time-demanding process. FlipFarm uses special shaped Hexcyl baskets and a flipping mechanism to streamline the flipping process. Butterfield converted to the FlipFarm process for both workflow & its tumbling effect, which contributes to a smooth and heartier, deeper cup on their oysters (read more here).
Of course it’s more than technology & technique. The spirit of the farm is best expressed by late founder Keith Butterfield, who describes a founding mission driven by passion for Casco Bay, sustainability & climate resilience, and cultivating a natural delicacy.
So here’s why we love Butterfields (and we’ll try to keep it relatively brief):
As you may have learned by now—with us or elsewhere—no two oyster farms in Maine are alike. Diversity of environment, algae, seasonality, tides, farm practices, equipment, histories, personalities, style, palette, goals, and cultivation dreams—people & place—translate to a diverse array of Maine oysters that brighten our plates, raw bars, and appetites. Again, their choice of FlipFarm technology & technique lends Butterfields a signature appearance. And as for flavor? Let’s taste…and talk taste.
Butterfield Shellfish is a family farm—but it’s hard to miss a connection between name & flavor. Butterfields are buttery (destiny?). As petite portals to their habitats, it’s no surprise that Butterfields also bring a vegetal, umami flavor forward, given the submerged plant & algal life near their grow site. The aroma is mild, bright; meat is full-bodied in a sturdy shell with a pearly interior. Light algal growth tints the exteriors caramel-colored, with subtle ridges or fluting telling the story of fast-flowing Casco Bay waters. Crisp finish, light brine, delightful sea-kiss linger. And as for shucking? With a consistent tear-drop shape and obvious hinge, shucking is smooth & approachable. Suitable for first-timers and seasoned shuckers alike.
Seasonally we—oyster farms—are flowing (like our tides) into full swing. Butterfield Shellfish is no exception. So a visit to the farm wasn’t in the cards for June; for now, we catch a snapshot of it in each oyster, as will you.
