The fastest growing carbonated water brand in the U.S. is gearing up for summer. Following the launch of its Ranch Water Hard Seltzer, Topo Chico Hard Seltzer has just introduced a Margarita Hard Seltzer variety pack for the summer months.

Focusing on exotic flavors drawn from iterations of the iconic Mexican drink, the ‘Topo Chico Margarita Hard Seltzer’ comes in Signature Margarita, Tropical Pineapple, Strawberry Hibiscus and Prickly Pear flavors. Each can evokes the complexity of the margarita with distinctive notes of lime, salt and tequila.

“Everyone loves a good margarita-it’s the No. 1 cocktail on premises for a reason, and it’s a natural fit for a brand like Topo Chico Hard Seltzer,” says Matt Escalante, vice president of hard seltzers for Molson Coors Beverage Co. “So we took what drinkers look for in a margarita, from the salty edge to the exotic fruit flavors to the citrus finish, and put it in an easy-to-drink sparkling mineral water,” he adds.

Topo Chico Hard Seltzer is on a roll, climbing to the number 4 spot of the best-selling hard seltzers in the US. It also has the highest repeat purchase rates of any sparkling mineral water launched in the last two years. And its original variety pack ranks as one of the top 10 best-selling variety packs, even though it was distributed nationwide for only three months.
