In 1975, Pepsi launched a bold marketing experiment that became one of the most famous case studies in branding history: the Pepsi Challenge. This blind taste test asked people to sample two unlabelled cups of cola and choose their favourite. The results were surprising. Time and again, the majority of participants said they preferred Pepsi’s sweeter, punchier flavour. On the surface, it seemed like a clear victory for Pepsi.
But the story doesn’t end there.
When the same test was conducted with the labels visible, the results flipped. Suddenly, most people declared Coke as their preferred drink. What was going on? If Pepsi tasted better in a blind test, why did brand awareness change the outcome?
The answer lies in the extraordinary power of branding.

The Science of Brand Loyalty
In 2004, researchers took this phenomenon a step further by examining the brain’s response to brand preference. Participants underwent MRI scans while drinking Coke and Pepsi, both blind and labelled. The findings were astonishing. When participants didn’t know which drink they were tasting, brain activity showed a similar level of enjoyment for both colas. However, when they saw the Coca-Cola label before tasting, the reward centres of their brains lit up significantly more than with Pepsi, even when drinking the exact same liquid.
This study revealed that brand is more than just a logo or a catchy slogan; it’s an existing expectation created before the product experience even happens. Perception is reality and a perceived positive opinion of a brand impacts the real life experience of the product, right down to the chemicals released in the brain. Coca-Cola’s decades of advertising, iconic imagery, and cultural associations had hardwired a this positive perception into people’s minds. That brand perception altered the physical response to the product itself.
The Implications for Businesses
The Pepsi Challenge teaches us a valuable lesson: a great product alone isn’t enough. In today’s crowded marketplace, competition is fierce, and consumers are spoilt for choice. To truly stand out, you need to build a brand that is distinctive, memorable, trustworthy, and offers something beyond the product.
Consider what makes your brand more than simply a product. Is it the story behind your business? The values you stand for? The feeling your customers get when they interact with you? These intangible elements influence how people perceive your product and, ultimately, how much they value it.
Building a Strong Brand
So, how do you harness the power of branding for yourself? Here are a few key takeaways:
Consistency is Key - Whether it’s your visual identity, messaging, or customer experience, consistency builds recognition and trust. Just as Coca-Cola’s branding evokes a sense of familiarity, your brand should offer a cohesive and reliable experience.
Emotion Over Logic - Buying decisions are often driven by emotion rather than reason. Tap into what your customers care about. Are they looking for comfort, excitement, or a sense of belonging? Craft a narrative that connects with those feelings.
Brand Building is a Long Term Strategy - Coca-Cola’s success didn’t happen overnight. It’s the result of decades of storytelling, innovation, and consistency. Building a strong brand takes time, but the rewards are lasting.
Beyond the Product
The Pepsi Challenge proves that branding isn’t just a nice-to-have; it’s a fundamental driver of perceived value. A great product might win a blind taste test, but a great brand wins hearts and minds. So, as you navigate your own competitive landscape, remember that your brand is more than what you sell. It’s how you make people feel.
And that’s where the magic happens.
