The name alone sounds like a childhood favorite. The Sour Apple Shock is a sweet and tart variety available in Cumberland Farms’ signature HyperFreeze slushy drink line.

Along with other candylike HyperFreeze flavors, such as Pinka-Saurus, Purple Palooza, Sucka Punch and Cotton Candy Commander, the Sour Apple Shock is a fluorescent green, apple-flavored beverage that Cumberland customers often mix with other HyperFreeze flavors, posting their creations on social media.
