Traditional grain mills in the Appalachian region of the United States are experiencing a resurgence after decades of decline due to the rise of processed foods. A growing consumer interest in natural products and traditionally milled grains is driving this revival. In Tennessee, the “Old Mill,” operating since 1830 on the Little Pigeon River, continues to grind corn using water power and heavy stones. This renewed demand reflects a broader “clean food” movement prioritizing quality and authenticity. The mills offer an alternative to mass-produced flours and cereals. The story highlights a shift in consumer preferences towards locally sourced and traditionally processed foods. This resurgence provides economic opportunities for the region and preserves a piece of Appalachian heritage.
