There are two types of people in the world. One type enjoys blue cheese, while others stick to cheddar. One group enjoys savory koblasniky to sweet kolache, and one type prefers to eat macaroni and cheese with a spoon or a fork. There is another defining category of people, and it comes down to an age-old question. Do you prefer Coca-Cola or Pepsi? Of course, it's hard to ignore both as each are huge corporations that own most of the sports drinks and snacks you see at Walmart and on Amazon.
However, if it came down to blind taste tests, would you be able to tell the difference between Coke and Pepsi on your first sip? As it turns out, it all comes down to flavor. In Malcolm Gladwell's Blink, published in 2005, he broke down the difference in taste and how it plays with people's taste preferences. In his research, he even pinpointed the exact difference that causes people to be Team Coke or Team Pepsi.
Coca-Cola, nutritionally, has a touch more sodium than Pepsi, which reminds us of Topo Chico or a club soda and results in a less blatantly sweet taste. Pepsi packs more calories, sugar, and caffeine than Coke. Although they both have carbonation and sweet flavor, the taste difference is undeniable. It's slight, but its there!
As he wrote,
"Pepsi is sweeter than Coke, so right away it had a big advantage in a sip test. Pepsi is also characterized by a citrusy flavor burst, unlike the more raisiny-vanilla taste of Coke. But that burst tends to dissipate over the course of an entire can. Pepsi, in short, is a drink built to shine in a sip test."
So while Coke has a vanilla-raisin taste that leads to a smoother sip of Coca-Cola in a taste test, Pepsi's citrus flavor stands out in those same taste tests because it's a sharp, zippy sip from the citric acid ingredient. It's the citrus tanginess of Pepsi that determines whether people will love it hate it.
What truly determines if what soft drink product you buy from Coke or Pepsi? The availability and name recognition of each option, including its offshoots like Diet Coke and Diet Pepsi. Coke's brand is considered more valuable than Pepsi and, as a result, is winning the war of the cola. How is Coca-Cola winning, though?
The Cola Wars
It all begins with Pepsi in the early 1980s. The marketing campaign, the Pepsi Challenge, set up a blind taste test between participants to determine if Pepsi was actually better than "the leading cola," which we all know to be Coke.
As Gladwell also found in his research about taste, people tended to prefer Pepsi in a single sip test because naturally, we're drawn to sweeter sips. It's proven by Pepsi's nutritional content that it has slightly more sugar than Coke, and therefore Pepsi tends to take home a sip test easily with a big advantage. However, it's when it comes down to the full can or glass bottle where Coca-Cola shines. Then, the bright citrus flavor of Pepsi doesn't hold up well to the smooth flavor of Coca-Cola.
So in 1983, when Pepsi-Cola really started outselling Coca-Cola in the cola market, Coke decided to revamp its formula and created New Coke, which was a sweeter taste designed to mimic Pepsi's success at those blind taste tests. Over 40,000 letters of complaint filtered into the Coca-Cola Company headquarters in Atlanta where execs were forced to reevaluate their decision.
Soon New Coke was phased out, and marketed with a twist that brought the old America history back to Coke by calling it Coca-Cola Classic. It again became so prevalent in the Midwest and the South that when Americans asked for a Coke, you had to check if they really wanted a soda or a Coca-Cola, and you still do. As for the beverage company rivalry, the rest is history.
So which do you prefer? A can of Coke or the Pepsi taste?
