About Duxbury Saltworks

Sea salt is a natural product with ancient roots, has a delicious taste, and is naturally infused with healthful minerals that are vital to our well-being. Our proprietary salt harvesting process, attention to detail & the purity of our product makes Duxbury Saltworks stand a tide apart.

Every six hours, the ocean waters of high tide gradually flow into Duxbury Bay. And every 6 hours after that, the waters of the bay gradually recede as low tide arrives — and the Bay’s sandy bottom is revealed. This natural cycle repeats each and every hour — a consistent, dependable, water-based renewal that provides the ideal environment for marine life, especially oysters, to thrive. It is from this pure and life-giving water that Duxbury Saltworks harvests our salt. We believe that every flake of our salt reflects its fresh, natural, and life-affirming origins.


Sea salt is evaporated ocean water (ocean water has approximately 3.5% salinity). When ocean water evaporates, a beautiful crystallization process occurs whereby salt crystals slowly begin to form. At Duxbury Saltworks, we carefully nurture the water into beautiful sea salt flakes — a true miracle of nature. Salt harvesting is an art in addition to a science. The science explains the “how” whereas the art invites, and necessitates, nuance. Our team spends countless hours examining each flake of salt we create. Our carefully honed salt making process produces the fluffy, flavorful, pure sea salt that Duxbury Saltworks is known for.


The harvesting of sea salt is the process of creating the salt flakes — which happens by hand in our facility. We have a Salt Harvester on staff who masterfully manages our salt harvesting process as opposed to employing a passive process ( e.g. letting the flakes form and raking them up, or collecting them from a salt mine, or even from a solar evaporation process which results in salt rocks, not flakes).

Duxbury Saltworks' Salt Harvester manages the time, temperature, and the rate at which we allow the salt flakes to form and dry. This proprietary process is integral to the creation of the pure, delicate fleur-de-sel style sea salt that Duxbury Saltworks is known for.


Sea salt provides dozens of essential minerals and trace minerals including potassium, magnesium, iron, iron, calcium, zinc, and selenium. Salt helps balance electrolytes, acts as an antimicrobial to help fight off microbes in our bodies, and so much more.


Processed table salt (think salt shaker) is produced in a factory setting where it is stripped of minerals and nutrients until it is just sodium chloride. More often than not, chemicals are used in the process to dye the salt white, and iodine is added along with compounds to prevent clumping. Just as we know processed sugar is not good for us; similarly, processed salt is not the best option. Think of the following sweetener analogy: high fructose corn syrup is to table salt (processed) as honey is to sea salt (natural).

Moreover, table salt may have added anti-caking agents, such as sodium aluminum silicate or additive E-554. There are a total of 18 food additives that are allowed in salt which are not good for your health. Our sea salt has no chemical additives. If you season with our sea salt, you'll avoid chemicals AND ingest salt flakes full of minerals and essential nutrients.


Yes. We have the water independently tested regularly per local guidelines, and it's incredibly clean! Very large ten foot tides bring fresh water in and out of the bay following mother nature's tide schedules. Millions of oysters filter the water in our bay every single day. Fresh minerals, nutrients and salinity infuses the sea water resulting in a tasty, flaky, beautiful salt.

To further refine the source of our delicious sea salt, our water is triple-filtered down to less than 1 micron on industrial scale filters. Our water is tested monthly by a widely trusted independent lab that specializes in water quality testing and is listed as a state-approved testing facility in Massachusetts. Moreover, because we harvest in small batches, we have an extremely high quality assurance standard. Nothing but pure salt water and minerals remain! Just message us if you would like more information.


When you start thinking about salt, you will quickly realize it's in almost everything you eat — whether added or naturally occurring. To bring out the natural flavor of any food, just add salt. A good quality, well-textured salt will enhance the dishes you cook in a natural, healthful way, infusing dozens of minerals and essential nutrients into your meals. As mothers, food lovers, garden growers, and salt harvesters, we will share recipes, inspirations, salt blends, and more with you as our business evolves.
