Naperville might be getting its first dirty soda shop.

Swig, the Utah-born drive-thru chain that trademarked the term "dirty soda" in 2013, has signed a 13-unit franchise deal to expand across Chicago's southwest suburbs, with Naperville among the planned locations. The Naperville store is expected to open in 2027, franchisee Derek Hincks told Patch, though no specific address has been announced.

A Naperville city spokeswoman said as of mid-July that the city had not received any permit applications from the company, according to NCTV17.

The franchise agreement, announced July 7 through Franchising.com, pairs Swig with Hincks and his wife Michelle, who operate under Sip City Social LLC. The couple relocated to the Chicago area in 2020 and bring experience in franchise operations and community engagement, according to the company.

"We've admired Swig for years, not only because it created the dirty soda category, but because of the way the brand brings people together and makes every visit a fun, memorable experience," Derek Hincks said in the July 7 franchise announcement.

The chain's first Illinois location soft-launched Monday, Aug. 17, in Crest Hill at 1701 N. Larkin Ave., with a grand opening planned for Labor Day Weekend, Sept. 4-5. Locations in Bolingbrook and Romeoville are also slated for 2027.

For the unfamiliar: a dirty soda is a customizable, nonalcoholic drink made by mixing fountain sodas like Coke or Dr Pepper with some combination of creamer, flavored syrups, fruit juice or puree. The dairy gives it a cloudy, or "dirty," look. The trend originated in Utah's Mormon community, where caffeinated coffee and tea are traditionally avoided, and gained national visibility through TV shows and viral social media posts. Dirty soda menu penetration grew 42% in 2025, according to The Food Institute, while traditional soda stayed flat.

Founded in 2010 in St. George, Utah, by Nicole Robison, Swig now operates more than 150 locations across 16 states. Its drive-thru-centric model can fit in as little as 800 to 850 square feet, eliminating the need for a full kitchen. Beyond dirty sodas, the menu includes water-based "Refreshers," customizable energy drinks called "Revivers," and snacks like a pink frosted sugar cookie and pretzel bites.

The format has drawn comparisons to 7 Brew, the drive-thru coffee chain. Dumont Creamery & Cafe, another new food-and-beverage concept, opened its first Illinois store at Block 59 (448 S. Route 59, Suite 104) on Aug. 7, part of a wave of national brands choosing Naperville as their Illinois beachhead.
