Dirty soda is a beverage that became popular in the U.S. Mountain West in the 2010s, and in the 2020s began to expand to a national consumer base. Made of soda "spiked" with cream and flavored syrups or fruit juices, the drink has been described as a "alcohol-free mocktails with optional flavor, cream and fruit add-ins", with a soda base, often sold at drive-through retail locations. Two Utah companies, one based in the Salt Lake Valley and the other based in St. George, were engaged in a lawsuit over who owned the "dirty soda" concept; the suit ended in 2017 with a settlement.
