Squirt is a caffeine-free citrus-flavore soft drink created in 1938 by Herb Bishop. Bishop created a new carbonated drink that required less fruit and less sugar. In Bishopβs opinion, it was the freshest, most exciting taste in the marketplace. Bishop gave Squirt its name because the drink seemed to "squirt" into your mouth like a freshly squeezed grapefruit. Squirt is naturally flavored and contains grapefruit juice (less than 1%). Another version, Ruby-Red Squirt, which is a citrus-berry flavor and contains caffeine, was created in 1993 with the help of Squirt Chemist Roy D. Hugh, who also pioneered the use of aspartame in soft drinks in the United States.
