Mug Root Beer was introduced in 1947 by the Belfast Beverage Co. of San Francisco California as Belfast Root Beer. By 1955, the name was changed to Belfast Old Fashioned Mug Root Beer, and later to Mug Old Fashioned Root Beer. The product was acquired in 1986 by the Pepsi-Cola Company.
Dr. Swett's root beer went off the market sometime in the early to middle 1950's.
