The world is basically divided into people who like Pepsi and those who prefer Coke.
Pepsi lovers SWEAR their soda is more refreshing, while Coke fans stand by their soda's classically sweet taste.
And despite all the debate, no one's really nailed down what's so different about the two flavors.
Well, it actually turns out author Malcolm Gladwell's already done just that.
In a passage from his 2005 book Blink, recently resurfaced by Foodbeast, Gladwell explains the difference between the cola rivals in a single sentence: "Pepsi is characterized by a citrusy flavor burst, unlike the more raisiny-vanilla taste of Coke."
In fact, if you look up each soda's ingredients, you'll notice that while Pepsi includes citric acid in its list...
...Coke is made up of the same ingredients, minus the citric acid and added sugar.
Not that the explanation settles which flavor is better.
