Bitter Kas soda

Bitter Kas is an iconic non-alcoholic carbonated beverage that originated in Spain. Known for its distinct red color and bitter flavor derived from herbal extracts and citrus, it was first launched in 1966 by the Knorr family.

Starting as a local Spanish innovation within the Kas brand (originally founded in Vitoria-Gasteiz), it quickly became a staple in Spanish aperitif culture. Today, the brand is owned and managed by PepsiCo, who maintains its production primarily in the Spanish market where it remains a cultural favorite. The drink is often enjoyed on its own with a slice of orange and an olive, reflecting its deep roots in Mediterranean social traditions.
