8 Diet Coke Alternatives, Reviewed For Quality and Taste

Good & Gather Cherry Cola Caffeinated Sparkling Water (8 pack) ($3)

This beverage, available at Target, is an unsweetened, lightly-flavored sparkling water with hints of cherry at first sniff and sip. It's definitely my favorite of the two sparkling water alternatives on this list. Each can has 35 milligrams of caffeine from green coffee extract and natural flavors that provide the twist. If you're not one for highly-sweetened beverages and love both Diet Coke and seltzer, I recommend trying this alternative as your new go-to — especially given its lower price point in comparison to others on this list.
