Sea salt is the result of evaporated ocean water — plain and simple.
We can't tell you how many people don't realize this! In all honesty, neither did we when we first googled "how is sea salt made" LOL!
The ocean is approximately 3.5% salinity, and true to form, we have found that we create approximately 3.5 ounces of sea salt per gallon of water. And that's where our process begins, with pure, clean water from Duxbury Bay, Massachusetts.
The water source is first and foremost. We can't overstate how lucky we are to live and work steps from the beautiful Duxbury Bay. It is a unique bay with qualities that foster clean water: there are close to 40 million oyster in Duxbury Bay, which are filtering the water 24/7. The tides are high and full bay water turn over is every 9 days. There is no industrial activity and because the bay is shallow, large boats do not enter.
In addition to starting with a clean water source, our business is located at a waterfront facility that enables us to use industrial scale water filtration systems. Once pumped in from the bay, the water runs through several large filtering systems that filter the water down to .5 microns. Know how small that is? .5 microns is not even visible to the human eye under magnification. .005 millimeters or 1/180th the width of a human hair.
We collect the water from the filter in large barrels to be dispersed in to large kettles to begin the evaporation process...
Our next edition will dive in to the evaporation process and how and when the salt actually forms!
