In the last year alone, there was the maple syrup cola that Pepsi created in partnership with the International House of Pancakes, Coca-Cola 's Dreamworld flavor that is supposed to taste like the "surrealism of the subconscious" and the Pepsi Nutmeg launched for the World Cup. Usually followed by some sweepstakes and a major marketing promotion, the limited-edition flavors often generate a slew of internet buzz and articles about how the company "really went there" but ultimately get relegated to "remember these weird flavors from the soft drink's past" round-ups after a few weeks.. Given the bigger investment required and stakes of releasing something that may ultimately prove to be unpopular, flavors in a soft drink company's permanent roster are usually much more conservative -- the main drink, some sugar- and caffeine-free versions and a few "special" flavors.
