Why Taste and Smell Are So Powerful: The Science Behind Product Recall

Walk into a supermarket bakery, and you’ll smell fresh bread before you see it. That first pour of boiling water over the coffee in the morning will wake you up almost as much as drinking it would. And open up a pack of your favourite biscuits and you’ll be transported back to your childhood.

It’s something we’ve all experienced, but it’s much more than just nostalgia. There’s a scientific reason why taste and smell leave such lasting impressions, and it has important implications for retailers who are looking to create memorable shopping experiences.

The Shortcut to Memory

Most of our senses pass through an area of the brain called the thalamus before they’re processed. The thalamus is essentially our brain’s sorting office – the place all sensory and motor signals are organised and sent to the right places. But smell is different.

Smell doesn’t pass the thalamus, or collect £200. It goes directly to the olfactory bulb, which has close connections to the amygdala and hippocampus, which are the areas of the brain that manage emotion and long-term memory. This direct link is one of the main reasons smells can trigger vivid memories and emotional responses so quickly. Familiar smells don’t just remind us of something; they trigger the memory and recreate the emotion at the same time.

Unsurprisingly, psychologists have a fancy name for this. The Proust Effect. It’s named after the French writer Marcel Proust, who famously described how the taste and smell of Madeline cakes instantly brought childhood memories flooding back. It’s something that’s been heavily studied by neuroscientists, and the findings have always been consistent. Smell has a stronger connection to emotional memory than any other sense.

Why are we talking about it? Because for retailers, creating memorable shopping experiences isn’t just about what customers see, it’s about what they experience too.

Taste Builds Confidence

Smell might trigger memory, but taste does something just as valuable. It removes uncertainty. One of the biggest barriers to purchase for any customer is simply not knowing whether or not a product will meet their expectations. They can read the packaging, compare the ingredients and see all of the promotional bumf that goes with it, but until they’ve actually tried the product, there’s an element of risk.

Will it taste as good as it looks? Is it worth the price? Is it genuinely different from the alternative sitting next to it, or is the difference all in the packaging? Being able to taste the product through sampling answers those questions immediately. So instead of asking customers to imagine the experience, you can allow them to have it. This shifts them from assumption to certainty, and has a profound effect on purchasing behaviour.

The Difference Between Seeing and Experiencing

Retail has always relied very heavily on visual communication. Packaging, shelf-edge labels, promotional displays and digital screens are all designed to capture attention, and they’re incredibly effective at helping customers discover new products. But they can’t convince customers to take that next step and buy.

Being able to experience a product engages multiple senses at once. A customer doesn’t just see the product, they also smell it, taste it, and discuss it with a knowledgeable brand ambassador all within the space of a few minutes. Depending on the product, they can even hear it (like something with a good crrrrrunch). From the brain’s perspective, that’s a much richer experience than just seeing it on a shelf and having to imagine the rest! The more senses you can engage in an experience, the more memorable it becomes. It’s called ‘multisensory integration’, and it’s another thing that’s been studied a lot over the years. The findings are all the same – interactive experiences tend to leave a stronger impression than passive ones.

Why This Matters for Retailers

In a retail environment where shoppers are being exposed to thousands of products every single time they visit, creating a lasting impression is incredibly difficult. Visual merchandising still plays an important role, but it only plays to that one sense. Sight. Taste and smell work differently, engaging the brain in a way few other marketing tools can, making them a uniquely powerful tool for affecting memory, emotion and decision-making.

As retail media continues to evolve, there’s an increasing focus on capturing shoppers’ attention through digital channels and in-store advertising. Those tools definitely have their place, but they shouldn’t overshadow how important physical experiences are. Bricks-and-mortar retail has one significant advantage that online shopping can never compete with; it allows customers to engage with products using all of their senses. That’s where your real competitive strength is.

When customers can taste a new food product, smell a freshly brewed coffee or experience the texture of a premium ingredient, they’re no longer relying solely on imagination. They’re making decisions based on first-hand experience. For retailers, this creates an opportunity to offer something genuinely distinctive while helping suppliers introduce products in a way that’s engaging, memorable and commercially effective.

Customers remember the products they can taste, smell and feel for themselves. After all, people may forget a promotional sign or a digital advert they passed in the aisle. They’re far less likely to forget the product they tasted, enjoyed and took home with them.
