RED POP! A classic.
One of the original Faygo flavors, Red Pop started life in 1907 as a strawberry soda called, appropriately enough, Strawberry Soda. In the '60s the name was officially changed to "Red Pop" and sold in cans. Red Pop is available in regular or sugar free (if, like Alex Karras, you're trying to slim down).
Faygo also offers Original Red Pop made with real cane sugar (in bottles) for real retro enthusiasts.
