How the Mill Works - Operation of a Historic Grist Mill ...
How the Mill Works. It starts with the grain… Of course, grist mills grind a variety of grains, such as wheat, rye and corn. But in Rhode Island, particularly at Gray's Grist Mill, native grown corn, particularly Narragansett White Flint Corn, is the most common "grist for the mill." The corn is husked, then dried for 6 to 8 months.
