Another fighter has entered the Hard Seltzer ring: Sonic Drive-In! The famous chain of drive-ins are taking their popular Slush flavors and re-imagining them as hard seltzers! This means you possible could get your Cherry Limeade, Lemon Berry, and classic Limeade flavors in a 12-pack starting May 1! The seltzers will have around 5% ABV at 160 calories. Sonic has wisely chosen to skip selling the future drinks at their drive-thrus. Would you try a Slush flavored hard seltzer? What is your favorite Slush flavor?
