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 the O-So Grape flavor, the company added many new flavors and incorporated the tag line "O-So Good" and "O-So Delicious". The company later acquired the brand name Bubble Up which became a significant player among lemon lime sodas of the day. Produced in our plant in Mukilteo, WA. 12 -12oz glass bottled sodas.
