The Magic of Coffee

There is magic in coffee. Not metaphorically. Not figuratively. And definitely not like the modern constructs of daylight savings when, lo and behold, my phone clock genie grants me an extra hour of sleep in autumn, and the bastard steals it back in spring.

A different kind of magic. Older. Closer to the bone.

One late autumn afternoon, a woman walks into the café. She’s not from around here, you can tell. The suit jacket, the hesitation at the door - not because anyone here would mind, but because she’s carrying a corporate disquiet that casts an antisocial pall about her. She steps in anyway. Brave. Or desperate. Or both.

“Flat white, please. I’ll sit outside.” Polite smile that flattened in a blink.

I grind her coffee on the old Mazzer Jolly I won at a second‑hand auction. It makes its usual thwack‑thwack‑thwack, the sound of a barista’s heartbeat back then. The pour hangs ink‑like off the spout - sweet, steady, yielding. I made a double cut short, the kind of shot that warms the palate and straightens the spine. The ACF tulip cups are defiantly small, a rebellion against the era of mission‑brown soup bowls. Handle to the right, spoon at the back. Invisible choreography. I place her drink down softly on the table. Invisible hospitality.

She drinks. Shoulders still hunched.

I go back to sweeping the mound of grinds that always collects to the left - every barista from that era knows the mound.

Then she’s back.

“That was a really great flat white. Can I have another one?”

This time her smile reaches her eyes and stays. The air around her has loosened. Something has shifted. She even gives me a fiver for a tip - a fortune back then.

Same routine. Same sweet unctuous pour. Same silky milk. Same fumble at latte art.

But this time she drinks leaning against the glass façade, cup in her right hand, tapping her feet like someone who has remembered she has a body, her face soaking in the autumn sun.

That kind of magic. Real. Live. Transformative.

That was twenty‑three years ago.

I have witnessed countless tangible transformations, since then – coffee flexing its magic on people. From someone on their way to an interview who stopped by for their talisman, to then return announcing a new employer. The soon-to-be-wed couple who had to have their prenuptial piccolos before the big event. Let’s rewind a little, they actually met at Coffee Alchemy and love blossomed over delightful flavourful little shot glasses of coffee steamed milk.

Deals sealed, promises made, bold decisions undertaken, thoughts unravelling into clarity, all over a cup of coffee. Dismiss this all you want. But follow me. Or, more accurately, follow the nose.

The olfactory bulb is part of the limbic system that regulates raw emotion, memory, and flight-or-fight responses. The olfactory cortex includes the amygdala which processes not just emotions but also emotional memory. Smell is the only sense that brings about vivid and highly detailed autobiographical memories when triggered. We’ve all had this experience, when smelling something brings you back to a specific place, time and context so real, the flashback stops you on your tracks. The emotions felt at that time are also replayed. Who knew that the nose can also be a time machine? The experience is visceral and very Proust. No other cues, not even music, can stoke such powerful feels.
 

Enter the multi-billion dollar Scent Marketing and Ambient Scenting industries. Hedione is a synthetic aroma that induces feelings of comfort and social attraction. Perfumeries use it not just to uplift other scents, but also to bring about a sense of social attraction. Iso E Super, the so-called MSG of perfumery, also acts in a similar way, evoking a sense of safety and cocooning.  A boutique spa and health resort may want to freestyle its own Hedione/Iso E Super combination in the mud chambers. Bigger money is spent on commercial diffusers to nano mist such scents by hotels, casinos and showrooms to drive customer retention, increase in-store dwell times, and build permanent emotional connections with consumers.  Samsonite is well known for this, diffusing bespoke travel-inspired aromas to trigger positive vacation memories and inciting travel hopes. Corporate offices and big tech employ scent dispersion technologies to counter fatigue and boost focus. There’s gold in them thar noses.  

What does coffee have? Well, over a thousand volatile chemical compounds to be not so exact. While a lot of those are odorants, the human nose can only identify fewer than a hundred, but those few are potent. Let’s look at some of them.

Pyrazines are responsible for the roasty, chocolate, nutty and that classic coffee aroma. Furans formed when the polysaccharides in coffee caramelise in the roasting process add sweet, caramel, burnt sugar, toasted marshmallow notes. Butanedione, also in coffee, gives off buttery creamy notes. Butanedone is also the very same compound used in the food industry to create artificial butter flavor for movie theater popcorn. There are compounds galore, all smelling of something else, that are found in roasted coffee. But this collection of pyrazines, furans, pentanedione, butanedione, along with some spicy guaiacols comprise the main aromatic frame many people associate with freshly roasted, freshly brewed coffee.

And they’re powerful enough that studies found that the smell alone of ground coffee enhanced cognitive performance in terms of attention, quality of memory, speed of memory, and mood. It’s the quintessential oily rag. Alertness and cognitive ability awakened by mere whiffs of coffee. Looking for a café?  Let your nose and your mood guide you.

While the smell of coffee can get the engines starting, we’re not going to get far on smell alone. Plus, does anyone actually buy a cup of coffee just for the sniffs? The core flex of coffee is blocking adenosine resulting in the release of dopamine, norepinephrine and glutamate. Dopamine is one of the happy hormones. Norepinephrine mobilises the brain and body for action. Glutamate is the most abundant neurotransmitter in the brain, essential for cognition, memory, and learning. BANG! Everything is go, go, go, after a cup.

But there’s more! Another wonder of the aromatic compounds in roasted coffee is their adjacence to milk.  As an infant we have associated this with survival, security and comfort. Primal and primordial. Milk has imprinted on us as infants a sensory world that is sweet–fatty–creamy–warm, the emotional blueprint for “safe nourishment.” As adults we crave the memory of these flavours to help us get through the day, alive, intact, safe. Human milk lays down the first sensory map of safety — sweet, creamy, warm. Later in life, the roasted molecules of pyrazines, furans, and diketones echo that map through heat. We love them because they rhyme with the first flavour the human nervous system ever trusted.

Australians didn’t fall in love with espresso by accident. The intensity of espresso counterbalanced by the irresistible mouthfeel of warm textured milk is of one of modern life’s wonders. We fell in love because espresso dovetails perfectly with milk - a tight joinery of bitterness and sweetness, adulthood and infancy, alertness and comfort.

So, if you’re wandering through everyday life, like the rest of us, and you have on your back the weight of today’s troubles, in your mind the unwieldy knots and mazes of threads, the day ahead looking thick with the fog of uncertainty, have a cup of coffee. It’s a little magic.
