The Psychology Behind Iced Coffee Devotees, According to Experts

Imagine this: it's cold, windy, perhaps even freezing, and all you crave is an iced coffee. If you're anything like me, you're committed to clutching a $7 cold brew, condensation and all, year-round. No exceptions. But why? What makes iced coffee garner such a devoted fan base?

Firstly, let's break down the distinctions between hot coffee, iced coffee, and cold brew. Yes, there are significant differences. According to food and culinary scientist Jessica Gavin, "Hot coffee is prepared by brewing coffee grounds with hot water, resulting in a robust and aromatic drink served at temperatures above 160 degrees Fahrenheit. On the other hand, iced coffee starts as hot coffee but is subsequently cooled and served over ice, which mellows its acidity and bitterness, providing a smoother taste."

"Cold brew differs in that it's made by steeping coffee grounds in cold water at room temperature or cooler for 16 to 20 hours. This process prevents the full dissolution of acidic and bitter compounds, leading to a rich, less acidic, and less bitter brew with a naturally sweet flavor," Gavin explains. Cold brew is also typically served over ice.

In essence, iced coffees possess fewer bitter notes, making them more appealing and generally more satisfying to those with a preference for sweeter tastes, as coffee expert Johny Morrisson notes.

So, why does iced coffee have such a hold on its loyal fans? The reasons run deeper than you might think. Read on to explore the psychology of dedicated iced coffee drinkers and why iced coffee is often more satisfying than hot coffee, regardless of the weather or season.

**The Psychology of Iced Coffee Drinkers**  

When considering the psychological aspect of iced coffee, a lot can be attributed to humans' inherent love for habit and routine, as psychologist Dr. Deborah Gilman explains. "Once a routine is formed, it becomes ingrained. If iced coffee is part of a daily ritual, one might continue with it out of habit," she says. "Routine offers a sense of stability in an unpredictable world, and knowing what to expect can make people feel more secure and less anxious."

Dr. Gilman also points out that an iced coffee routine can bestow a sense of control. "Making the same choices daily reduces the number of decisions one has to make, conserving mental energy for more important tasks and helping to avoid decision fatigue," she notes. "Consistently repeated behavior becomes a habit, and habits are automatic actions requiring little conscious effort, making life smoother and easier."

Additionally, research published in the *Cureus Journal of Medical Science* in 2021 found that caffeine, whether from hot or cold coffee, can influence "feel good" neurotransmitters in the brain by stimulating the central nervous system, enhancing mood, reducing stress, and increasing feelings of pleasure, satisfaction, and motivation. However, Dr. Gilman cautions that excessive caffeine can heighten anxiety and stress, recommending no more than 400 milligrams—or about four to five cups—a day.

**Why Is Iced Coffee More Satisfying Than Hot Coffee?**  

From a technical standpoint, chilling coffee tones down its acidic and bitter notes, resulting in a smoother flavor, Gavin says. "The cold temperature suppresses TRPM5 channels—temperature-sensitive proteins on our taste buds—reducing flavor perception, which is why iced coffee is popular among those sensitive to coffee's natural bitterness and acidity," she explains.

Conversely, hot coffee served above 160 degrees delivers a stronger, more complex, and bitter taste. "High temperatures open up TRPM5 channels, intensifying flavor sensitivity, which might not appeal to everyone," Gavin notes. For those seeking a refreshing caffeinated drink with minimal bitterness, iced coffee is likely the better choice.

The refreshing nature of iced coffee is also a major draw. "Even in cold weather, the combination of the chilly beverage and caffeine's jolt can make people feel more alert and invigorated, whereas a hot drink can be more relaxing," Gavin says.

Moreover, iced coffee scores points for convenience, says Morrisson. It's straightforward to make at home or buy pre-bottled, and tall, lidded cups from cafés make it portable and easy to drink on the go without the risk of burning your mouth or spilling hot liquid.

Let's not forget that trend plays a role in the appeal of iced coffee. "Beyond taste, iced coffee carries a lifestyle appeal, especially among younger consumers, and major chains like Starbucks have turned iced coffee into a cultural phenomenon with buzzy seasonal offerings and trendy flavored lattes," Morrisson says.

Iced pumpkin spice lattes and brown-butter shaken espressos, for instance, resemble indulgent coffee milkshakes more than their hot counterparts. "They can be enhanced with creamers, whipped cream, caramel, chocolate, and more, making them taste like a treat," Morrisson states. They're also more visually appealing for social media sharing. "With many opportunities to showcase creative drinks on Instagram and TikTok, a pretty iced coffee has significant marketing appeal that hot drinks lack."
