Vimto is a soft drink sold in the United Kingdom.
 It was first manufactured as a health tonic in cordial form, then decades later as a carbonated drink.
 It contains the juice of grapes, raspberries and blackcurrants (in a 3% concentration), flavoured with herbs and spices.
 The original recipe was invented in 1908 by (John) Noel Nichols.
 Nichols grew up in the Lancashire town of Blackburn.
 It is often referred to as the rich man's Red Kola.
Grapico is a caffeine-free, artificially flavored carbonated soft drink with a purple color and a grape taste that is sold in the Southeastern United States.
 When introduced in 1916, the product quickly became a success, which in part was due to implying that Grapico contained real grape juice even though it did not.
 In the spring of 1926, J. Grossman's Sons sold the Grapico business to New Orleans business Pan American Manufacturing Co.
 Pan American continued J. Grossman's Sons' improper practice of implying that Grapico contained real grape juice and lost the right to use the word "Grapico" to designate their artificial grape drink in 1929.
Ironport (sometimes spelled as two words: Iron Port) is an old-fashioned carbonated soft drink from the early part of the 20th century that was served at soda fountains and is still popular in the Intermountain West.

 The flavor has been described as somewhat of a cross between root beer and Caribbean spices and is very similar to the Cuban soda, Iron Beer.
 The flavor has also been described as a black cherry Dr Pepper.
 It is rumored to have been named after Porter Rockwell.
