Raye's Mustard

Raye's Mustard has been cold-grinding mustard seed in Eastport, Maine since 1900. That's not a marketing line — it's the operational reality of the last surviving stone-ground mustard mill in the United States. The mill sits at the edge of Passamaquoddy Bay, at the easternmost point of the continental US, in one of the smallest cities in the country. It has outlasted Prohibition, two world wars, the collapse of the local sardine industry it once supplied, and the consolidation of the American condiment industry into a handful of multinationals.

J.W. Raye founded the mill to serve the sardine canneries that lined the Maine coast in the early twentieth century. Mustard is integral to the canned sardine trade, and Eastport was then a hub of Maine's sardine industry. When that industry faded, the mill could have closed. Instead it kept grinding, adapting its product line, and finding new customers who appreciated the difference that cold-stone grinding makes.

Cold grinding preserves volatile oils in the mustard seed — the compounds that give mustard its heat and complexity. Industrial mustard processing uses high heat, which drives off those oils and leaves a blander product. Raye's has never done it that way. You can taste it.

The mustard is barrel-aged after grinding, another step that industrial producers skip. The resulting condiments have a depth and complexity that's noticeably different from supermarket standards. Martha Stewart called Raye's one of her favorite local businesses. Yankee Magazine named it a Food Awards winner. The Atlantic covered it when American Futures visited Eastport.

The mill still operates as a historic landmark and working museum — you can visit, watch the stones turn, and buy directly. It's one of the rare places where a food product and the machine that makes it have survived together for over a century.

Why We List Them

Raye's is a 125-year-old independent mustard mill operating the last stone-ground mustard operation in America. It's never been acquired, never changed its process, and never left Eastport. In an industry dominated by a few corporate brands, a functional historic mill that still produces a genuinely superior product is worth pointing people toward.
