Instant grits and tube polenta are made from degerminated dent corn stripped of its oil so it never goes stale — which also means it never tastes like much. Real stone-ground grits from heirloom corn still have the germ in them, which is why they smell like sweet corn when they hit the water and why cooks drove all over the South to find them again.

Glenn Roberts tracked down near-extinct heirloom corn and brought it back on granite stone mills in Columbia, South Carolina. The grits and polenta are cold-milled organic and shipped refrigerated because the germ is still in them and will go rancid otherwise — the same reason 5,000-plus chefs order from him. This is the mill that essentially restarted the heirloom-grits movement.
Why it isn't on AmazonYou can't buy live, germ-in grits like these off a shelf because they're perishable — they're milled to order and kept cold. That perishability is exactly what a supermarket grit engineers out, and it's the whole point.
See it at Anson Mills →Greg Johnsman's family grows heirloom corn on Edisto and Wadmalaw Islands and grinds it on a restored 1945 gristmill — including bright 'Unicorn' grits milled from red corn. Formerly known as Geechie Boy, it's a working farm and mill in one, and it ships to all fifty states.
Why it isn't on AmazonThis is single-farm corn ground on an antique stone mill, not a commodity product. The colored heirloom varieties like the red-corn Unicorn grits simply don't exist in a grocery aisle.
See it at Marsh Hen Mill →A USDA-certified-organic gristmill in Columbia that hand-mills every batch of grits and polenta on stone only after you order — expect a two-to-four-week lead time. You choose the corn: white, yellow, blue, or red, each with its own flavor and color.
Why it isn't on AmazonThe multi-week wait is the feature — nothing sits milled on a shelf losing flavor. You're getting grits ground within days of eating them, in corn colors you'll never see at a store.
See it at The Congaree Milling Company →Will West and Mary Beers run a small stone mill on the Tar River in Nash County, North Carolina, grinding conventional, organic, and heirloom grits and cornmeal in small batches, all non-GMO. The cart caps around 12 pounds an order, which tells you the scale — this is a two-person operation, not a factory.
Why it isn't on AmazonSmall-batch stone-ground grits from a two-person mill, with an heirloom option, at a friendlier price than the collector-grade mills. The tiny order cap is the honest sign you're buying from actual people milling to keep up.

In practice a lot of it comes down to region and grind, and several of these mills sell corn that works beautifully as either. Cook them the same way: low and slow with plenty of liquid.
Stone-ground grits keep the corn's oily germ, which is where most of the flavor lives — and that oil goes rancid at room temperature over a few months. Supermarket grits are degerminated, stripping the germ out so the product is shelf-stable for a year or more but far blander. If a bag of grits tells you to refrigerate or freeze it, that's a good sign the germ is still there.
Real stone-ground grits take 30 minutes to an hour of low, steady simmering with frequent stirring, versus five minutes for instant. The reward is creamy texture and deep corn flavor you can't rush. Soaking them overnight in their cooking water cuts the time down and improves the texture, and any leftovers reheat well with a splash of liquid.
Heirloom corn refers to old, open-pollinated varieties — many nearly lost — that were grown for flavor before industrial hybrids bred corn for yield and shipping. Mills like Anson and Marsh Hen revived specific near-extinct landraces, which is why you'll see named varieties and unusual colors like red and blue. These taste distinctly of corn in a way modern commodity dent corn doesn't.
