Swan's Dairy had its beginning in 1923 with one cow. In 1951, Swan Dairy started selling Grade A Raw Milk in 1 gallon bottles and continues today. The first milk was 50¢ a gallon. There was not a clerk on duty...the honor system was used.
Visitors are welcome to view Oklahoma's finest milk as it comes directly from the cows to a pre-cooler and then to a tank cooler and bottled. The cows are not given hormones, and the pastures are not chemically sprayed. The raw milk is routinely tested by the State Health Department.
