This September, 16 Handles is partnering with Welch’s for the ultimate back-to-school flavor—Welch’s Mighty Concord Grape. Made with Welch’s Concord grapes, this flavor packs in all the delicious flavor of Welch’s with the cool refreshing taste of 16 Handles Fro-Yo.

In celebration of the launch, 16 Handles app rewards members get a sweet treat on September 15th between 2pm and 6pm. Rewards members who have downloaded the 16 Handles app will receive up to 3 oz of free Fro-Yo simply by presenting the app at the register.

“Welch’s is a back-to-school must have, and we’re excited to partner with them just in time for the school year. Welch’s Mighty Concord Grape is made with real Welch’s Concord grapes for an authentic and delicious taste. The collaboration is also a nod to our throwback roots—nostalgia is a big aspect of 16 Handles,” says CEO and founder, Solomon Choi, who named the popular chain after the cult fave 16 Candles.

Try one of these combinations to create the ultimate frozen treat:

Grapes of Wrath: Peanut Butter Sauce, Nuts, Yogurt Chips

The Grape Gatsby: Peanut Butter & Jelly Cups, Whipped Cream, Almonds

Grape Expectations: Mochi, Peanut Butter Cups, Ghirardelli White Chocolate Sauce

This month, 16 Handles is also traveling back in time to the ‘80s with The Goldbergs. To celebrate the popular show’s broadcast syndication launch, which will give viewers the chance to enjoy the family comedy every weeknight, the beloved frozen dessert shop will be offering three throwback toppings—Reese’s Pieces, Keebler Fudge Stripes Cookies, and Nestle Crunch Bar—all in honor of this totally awesome decade. The Goldbergs will be broadcast every weeknight at 7 & 7:30 P.M. on WPIX in New York and on Tribune Stations across the country starting September 11.

“We’re excited to celebrate The Goldbergs syndication launch with these throwback toppings,” says Choi. “As a kid who grew up in the ‘80s, these toppings take me right back to my childhood.”

“16 Handles, like The Goldbergs, is a destination for family fun. Partnering with them to create the special limited edition 80s-inspired toppings is by far the sweetest way to celebrate the premiere of The Goldbergs on PIX-11 every weeknight,” adds Rachel Mizuno, Senior Vice President, U.S. Distribution Marketing.

16 Handles will offer The Goldbergs throwback toppings throughout the month of September in its locations within the New York metro area.
