What are brown specks in grits?

Brown specks in grits are often bits of the outer hull or bran from the corn used to make the grits. These specks can occur more frequently in stone-ground or whole grain grits, which retain more of the natural corn kernel. They are generally safe to consume and may even add a bit of texture and flavor. If the specks are accompanied by an off smell or any signs of spoilage, it’s best to discard the grits.
