Purity Dairies is a Nashville, Tennessee, based dairy company operated by the Ezell family. It offers products throughout Tennessee, Alabama, and Kentucky. The company is owned by Dean Foods. In 1926, Dr. C.N. Cowden sold his dairy farm to Miles Ezell after he had rented it for a year, and it was named Ezell's Dairy. By the 1940s, many local dairies had closed due to the requirement of pasteurization, and Ezell's Dairy was one of the few that remained. In 1945, the farm was shut down, but Ezell obtained a small business loan, bought the Green Vale milk plant on Murfreesboro Road, and merged... with Rosebank Dairies. In 1946, the company was formally incorporated as Purity Dairies. Albert Gasser joined the company as President and his high standards and commitment to quality helped Purity become the dominant milk producer in middle Tennessee. Purity at one time promoted itself as a provider of "Golden Gernsey" milk. Later, it stressed its "GoldenFlake" buttermilk and won many national awards with this product. Purity was one of the first to use HEPA filtration in its cottage cheese production area and this helped to dramatically improve the shelf life of the product.
