Inside the Double Cola Co. bottling plant at 1300 W. Franklin St. This bottling plant no longer exists. According to Wikipedia, Double-Cola is the name of a carbonated soft drink. It is manufactured by The Double Cola Company, headquartered in Chattanooga, Tennessee. Double Cola was formerly available in a somewhat wider area of the South. Yet Double Cola is a distinctive part of culture in Southern Indiana, especially around Evansville (for example, Double Cola Fields). It was once marketed as a lower-cost alternative to Coca-Cola and other soft drinks, but Double Cola is now marketed as a premium brand in that area, with the same or higher price than Coca-Cola or Pepsi-Cola.
