Mezzo Mix is a product of the Coca-Cola Company sold only in Germany, Switzerland, Austria and Finland. Its slogan, translated into English, is "Cola Kisses Orange". It is basically standard Coca-Cola with a light orange flavor, much like a Spezi, which is usually Coke mixed with orange Fanta.
There were two kinds of Mezzo Mix in the 1990s: orange and lemon. The latter was unpopular and was discontinued, but a lemon-flavored Coke entered the market again in 2003.
