There were no words on the bag giving any clues to the flavor, but perhaps the color of the letters might give you a clue. The chips had a sweet flavor, and our tasters couldn't figure out whether it was more lemon- or lime-flavored. Some guesses included key lime pie, margarita flavors, etc.
In the end, we decided it was Mountain Dew flavored, which made sense if you went to the Doritos Interweb site and played the game (which is no longer there). They were offering a chance to win $100,000 if you could solve a series of puzzles. The first puzzle's answer was Mountain Dew.
