Established in 1946, O-So started as an independent soft drink company based in Chicago, IL. By the end of the 40’s the Company had a network of bottlers in nearly all metropolitan markets throughout the country. Originally famous for its O-SO Grape flavor (which we do carry), the company added many new flavors and incorporated the tag line “O-So Good” and “O-So Delicious”. This pack is made up of 10 – 12 oz. glass bottles of O-So Butterscotch Root Beer.
