O-SO Butterscotch Root Beer will not fail you with its rich notes of butter and brown sugar with the added treat of root beer to round out the creaminess.
Established in 1946, O-SO started as an independent soft drink company based in Chicago, IL. By the end of the decade the company had a network of bottlers in nearly every metropolitan market in the country. Originally famous for its O-SO Grape flavor, the company added many new flavors and incorporated the lines “O-SO Good” and “O-SO Delicious” into its sales and marketing materials.
