MTN DEW, a brand PepsiCo, is releasing the latest iteration of its limited-time only flavor ― MTN DEW Voo-Dew ― for a third year in a row. Those who believe they’ve uncovered the mystery are encouraged to share their flavor guesses on social media using the hashtag #VOODEW and tagging @MountainDEW. MTN DEW saw a huge spike in social conversation last year around the mystery flavor, Fruit Candy Explosion, and now we want to do it again, it says. Beginning Aug. 30, MTN DEW Voo-Dew will be available for as long as supplies last at participating retailers across the United States.
