"Rock & Rye" is also the name of a popular cocktail front the late 19th century made from rye whiskey sweetened with rock candy and flavored with citrus fruits and herbs, which was renowned for its medicinal benefits. Faygo's cherry-cream-soda version of the drink does not seem to have much relationship to the alcoholic version of the drink aside from its sweetness. Was it meant to evoke lost memories of the cocktail during the Prohibition years of the 1920s? Or was it meant as a ready-made mixer for cheap Canadian whiskies which were easy enough to come by in Detroit during those years?
