Filter Stories - Coffee Documentaries (James Harper)

To roast coffee faster, you need to turn up the heat….right?

 

No! 

 

In this episode, we explore the three powerful methods of heat transfer that revolutionised roasting. We’ll journey from humble beginnings—when roasting three kilos took half an hour—to machines that now roast hundreds of kilos of coffee in the time it takes you to boil a kettle. 

 

But beans roasted at lightning speed look strange, and taste… well, you’ll find out. Join us as we test-drive an industrial tangential roaster where first crack remind me of fireworks crackers. 

 

We also see the whale-sized roaster so massive it’s worth you a Guinness World Record. 

 

We have the technology today to roast coffee faster than ever, so why aren’t we all roasting at recording-breaking speeds?

We’re back with another series of The Science of Coffee—and this time we’re diving even deeper into coffee’s hidden microscopic secrets!

 

Over the past year, narrative audio producer and coffee professional James Harper has scoured academic journals, ventured deep into coffee farms, and conducted bold tasting experiments.

 

Now, he’s weaving those discoveries into captivating audio stories that reveal why coffee tastes the way it does—and how we can make it taste even better.

 

In this new series, you’ll learn about cold brew extraction science, explore innovations in roasting, and follow the shifting business models that shape farmers’ livelihoods. You’ll also take a journey through commodity vs. specialty supply chains and examine the historical, sociological, and philosophical perspectives that define what “specialty coffee” truly means.

The Coffee Quest | BWT | TODDY | Algrano | Probat

When I started making cold brew this last year, I treated it like hot brew filter coffee. But no matter how I adjusted the grind or tweaked the brew time, I hardly got any differences in flavor…

 

Then it hit me: cold brew isn’t just a slower hot brew—it’s a completely different game with its own rules!

 

In this episode, I speak with leading coffee researchers who break down the microscopic dance between water and coffee that explains why cold brew plays by its own playbook.

 

And I bring you in on the brewing secret that can turn your brews from fruit juice to nutty creaminess.

The Coffee Quest | BWT | TODDY | Algrano | Probat

For years, I used cold brew as a last resort—the only brew method to tame dark, oily beans that were too bitter for hot water. 

 

Then one day, I took a chance on a Guatemalan Gesha and brewed it cold. The result? A massive explosion of florals I’d never tasted before. That single cup sent opened my eyes into how extraordinary cold brew can be.

 

In this episode, I speak with world-leading coffee scientists who explain why brewing with cold water tastes so different from chilled hot coffee. 

 

You’ll learn how certain flavors leap into your cup (and how others mysteriously vanish) when you lower the brew temperature.

 

You’ll also discover there are hidden “cold brew gems” in beans you thought you knew. So before you grab the kettle, consider this: sometimes all you need is cold water.

A mother coffee plant gifts its baby everything it needs to grow—a green seed packed with food. But when we roast coffee, we hijack that gift and turn it into something else: flavor.

 

But what is flavor, at a microscopic level? What actually happens inside the bean when heat meets those nutrients?

 

In this episode, we shrink down to witness the Maillard reaction up close—a wild chain of molecular collisions that transforms baby plant food into aromas we adore. 

 

Grab your popcorn - you’re getting a front row seat at the wildest chemistry show in coffee.

A History of Coffee is the story of how a tiny psychoactive seed changed the world and shapes our lives today. Across six episodes, documentary maker James Harper and professional historian Jonathan Morris narrate how humans race coffee across oceans to keep up with demand for this addictive drink. Coffee creates enormous fortunes for some, and misery for others. Sometimes the environment benefits, but more often it is plundered. If we want to make coffee a more equitable industry that’s also kinder to the environment, a place to start is understanding the stories and systems that put the coffee into your cup this morning.

Here’s a surprising fact: coffee was only invented around the time Michelangelo was chiselling his statue of David. Why did it take so long for humans to invent the cup of coffee? In this first episode of A History of Coffee, Jonathan and James unpack how humans figured out that delicious flavours were contained in the roasted seeds of a coffee tree’s cherries. The answer has nothing to do with dancing goats...but, in some ways, it has everything to do with a shepherd in the forests of Ethiopia.

A hundred years ago one Brazilian man owned so many coffee trees he could fill every inch of a European country with them. But why does Brazil grow so much? And who is drinking these lakes of caffeine? In this third episode of A History of Coffee, Jonathan and James explore how industrialisation dramatically and permanently strips away Brazil’s forests, and why coffee becomes a part of the American dream.

How do you drink your instant coffee? If you’re like most of the world, you fill your mug with milk and sugar to sweeten the taste. By adding milk and sugar to your instant, you helped bring new growers - and consumers - into coffee, but arguably contributed to a crisis that left hundreds of thousands of people malnourished. In this fourth episode of A History of Coffee, Jonathan and James explore how the popularity of instant coffee dramatically alters the balance of power amongst coffee growing countries. Coffee as a global commodity takes on a life of its own, sweeping millions of farmers into a race to the bottom.

Do you grind your beans fresh before brewing your coffee? If so, you are helping overturn a race-to–the-bottom with deep roots in colonial extraction that today is leaving millions of coffee farmers impoverished. Or, at least, that’s what many specialty coffee companies would like you to believe. The truth is a lot less rosy. In this final episode of A History of Coffee, Jonathan and James explore where the specialty coffee movement came from, whether it will succeed in arresting coffee’s race-to-the-bottom, and look into the future to understand what might be the future of coffee.

Sri Lankan coffee has delicious notes of chocolate and caramel. But it’s basically impossible to find, and we’re going to bet you’ve never drank it. But that's really odd, because Sri Lanka has the perfect climate to grow coffee, and was once one of the biggest coffee growing countries in the world. But Sri Lanka was the victim of an ecological ticking time bomb. And this bomb is still ticking, and is going to explode again. In this special episode of Adventures in Coffee, producer James Harper takes co-hosts Scott and Jools on an adventure back in time, across Ethiopia, Yemen, Sri Lanka to trace the origins of this ticking bomb, and what it’s going to take to defuse it. — Subscribe to Adventures in Coffee here: https://bit.ly/300V4jS Sign up for the 2022 Barista League's High Density (free!) conference here: https://bit.ly/3BjAI78 Read Stuart McCook’s excellent book, Coffee Is Not Forever: https://bit.ly/3320rob And follow his Instagram: https://bit.ly/3sJ2OVI Follow Hansa Coffee on Instagram: https://bit.ly/3sOyLfr Listen to James’ stories about El Salvador here: https://spoti.fi/3Lcnuhg Help other people find the show by leaving a rating on Spotify: https://spoti.fi/3JYduHY Help others find the show by creating a screengrab of this episode on your podcast player and sharing it on your Instagram stories.

Water really matters when you’re brewing coffee. Different waters can dramatically change how a single coffee will taste. But what is the right water for the best coffee? In this episode I will give you the answer, but I will first take you back billions of years to tell you the story of a single mineral and how it's responsible for making our coffees taste lame. Because here’s the thing: water science is chemistry, and chemistry is very complicated and easily forgettable. But with a great story, I’m hoping you’ll remember! In the second half, I show you why Christopher Hendon’s book Water for Coffee made a big splash in the coffee community, but also why some academic chemists are critical of the book, and how this all manifested in the creation of the Specialty Coffee Association’s Water Quality Handbook. And, to cap it all off, I offer you some environmentally conscious ways to get hold of good water for coffee, so your coffee brews can finally explode in flavour. —--- Please spread the word about The Science of Coffee!

How you brew your coffee dramatically affects what you taste. And I do mean dramatic! Brewing up the same bag of coffee beans can taste like a slice of heaven, or a slap in the face. So, what exactly is happening at a microscopic level when water swirls through coffee grinds? Why does boiling water extract certain flavours, while letting the kettle cool for five minutes make it taste markedly different? In this episode, we dive deep into the academic research conducted at the UC Davis Coffee Center so you can choose your flavour adventure: Do you like your coffees when they’re a sour bomb? A floral caress on the lips? A smokey drag on a pipe? Or a treacle of sweet syrup? We also explore why it can be so difficult getting the same flavours from the same beans consistently. And finally, I equip you with tools so you can begin finding your perfect brew. —--- Please spread the word about The Science of Coffee!

How can you make better coffee at home? Well, an easy way is to buy higher quality beans. But, I’m concerned this is going to get harder and harder for you in the future. Climate change is making coffee taste worse while also pushing farmers into financial hardship. In this episode we explore how genetic development can produce a coffee tree that might save the day. Is there a wild coffee tree happily growing in the forests somewhere that could be our silver bullet? What about if we mix existing documented species together? But, the big problem is that genetic research is slow, and farmers can’t wait around. So, in the second half, we learn how coffee farmers in Kenya are trying to fix the problem right now. And I’m actually tentatively hopeful the beans you brew in the morning are not going to get worse.

A good espresso is a sublime experience: rich, sweet, and wonderfully caffeinated. But, who woke up one morning and thought to themselves, ‘I’m going to build a contraption that forces a tiny amount of super hot water with incredible pressure through a bed of very finely ground coffee’? Well, the fact is, the first “espresso” machine built 150 years ago was awful in almost every way. Worst of all, if you gave that coffee to anybody on the street, nobody would say it’s even an espresso! But, over the decades, problems begat solutions that begat more problems that culminated in espresso machines like Eversys that produce gorgeous espressos at just the push of a button. And it’s got me wondering: what is the perfect espresso machine? How far can we go?

When was the last time you picked up a cappuccino with a mountain of foam perched on top? Maybe these are the cappuccinos you make every morning at home. I personally really, really dislike them! The foam is cold, raspy, and gets in the way of the actual coffee liquid. How much better would your mornings be if, instead, your cappuccino had that creamy, silky “microfoam” you find in a specialty coffee cafe? In this episode, I take you deep into the bubbles of latte foam to show you what makes them, what destroys them, and how you can craft mouth-melting lattes.

Imagine you’ve got a cup of coffee in front of you. You haven’t tasted it yet. You therefore don’t know what it tastes like, right? Wrong. Some scientists argue that you actually do know what it will taste like (more or less), and the act of tasting simply confirms what you have already imagined it will taste like. And that’s because a growing body of research is revealing that sight, sound and touch all affect your expectation of a coffee’s flavours. In this episode, I explore how certain sounds might make your coffee taste sweeter, while other sounds translate to bitterness. And I expose how some cafe owners might be ruining the flavours of the high-end specialty coffee you paid for without even realising it. In the second half, I show you why so many of our scientific questions about coffee are going unanswered. I take you deep into the future of coffee science by explaining who’s doing research into coffee science, why they’re doing it, how much it costs and how you can get involved. ---------- Please spread the word about The Science of Coffee!

We're back with more stories about the tiny psychoactive seed that changed the world and continues to shape our lives today. In Series Two, we reveal how the invention of the coffee shop revolutionised societies, why colonialism, racism and coffee have kept once prosperous Haiti poor today, how Italy's revered espresso culture was created, and we debunk many myths around America's supposed love affair with coffee. If we want to make coffee a more equitable industry that’s also kinder to the environment, a place to start is understanding the stories and systems that put the coffee into your cup this morning.

A coffee shop is a lot more than just a place to drink coffee. The seats and sofas encourage you to invite a friend, and chat. And chatting is powerful: ideas that emerge from these caffeine-fuelled conversations give birth to modern finance and even the founding of great artistic and scientific institutions. Meanwhile, other ideas threaten those in power, and have led to many attempts to ban coffeeshops (and even coffee itself!) these last 500 years. In the first episode of Series Two of A History of Coffee, we show you how the coffee shop changed the world, and we ask whether it still has what it takes to upend society.

Haiti was once the biggest, most profitable coffee growing region in the world. But today Haiti is one of the world’s poorest nations where you can’t get a bag of Haitian beans delivered to Berlin in a week for love nor money. In this second episode of Series Two of A History of Coffee, we show you how colonialism and racism dragged Haiti into poverty, and the role of coffee at the centre of it.

One morning back in the ‘80s, Howard Schultz walks out of his Milan hotel, stumbles into an espresso bar, and fundamentally changes coffee history. He discovered (and then popularises) the iconic, timeless Italian coffee experience: Rich thick coffee, an affordable price and great theatre. But this Italian ritual is surprisingly young, so young that Howard Schultz was in school while some of it was being developed! In this third episode of Series Two of A History of Coffee, we show you why for most of Italy’s history, coffee was thin, expensive, dull to watch…and that’s if you were lucky enough to even be drinking the real stuff at all!

America is coffee-obsessed. From Central Perk’s red couch being the centre of major plot twists in Friends to the fact the average American drank more than two cups a day. And the conventional explanation is pretty straightforward: an English colonist introduces coffee to Jamestown in 1607. 150 years later Americans rebel against the British by throwing tea chests into Boston harbour and drinking coffee becomes their patriotic duty. Oh, and of course who won the civil war? The side that had the coffee. But, actually, the truth is much more surprising, and reveals a much more counter-intuitive story of America. In this final episode of Series Two of A History of Coffee, we offer you a story of America through the lens of a black drink, another black drink, a third black drink and perhaps even a fourth.

So you’ve just taken a sip of a very rare coffee, and flavours of passion fruit explode in your mouth. But here’s the thing: that flavour of passion fruit is not coming from your mouth. It’s not even coming from your nostrils. It’s being picked up behind your eyes! In this first episode of The Science of Coffee's second series, I unravel how our sense of smell and taste works to help you be a better coffee taster. I shrink us down microscopically and we dive into your tongue to show you why good black coffee tastes sweet, even though there’s no sugar in it. We then travel up into our noses and get stuck in a lot of mucus. This slime might be disgusting, but we need it to be able to smell well. And finally, with the help of tasting expert and author Mandy Naglich, I show you three effective ways you can train yourself to be a much better coffee taster without having to go on any expensive courses. The trick is to train our internal flavour prediction models!

What flavours do you want from your coffee? Every coffee bean begins its life green. And if you brewed it up without first roasting it, you’d get a yellow-green cup of grass-flavoured water. But, as soon you apply heat to a bean, the flavour can morph to from something quite vegetative to a very acidic unripe fruit, then a very sweet fruit, and eventually dark roasted flavours. This is the magic of coffee roasting! In this episode of The Science of Coffee, I show you a full roast in action on the ROEST P3000, taste how coffee flavours evolve from acidic to bitter, and speak to leading coffee roasting scientists to reveal the mind-bending chemical and physical transformations taking place.

Roasting coffee can be maddening. Just 4° Celsius is enough to make the same green beans taste distinctly different! And there are so many things roasters can play around with: temperature, time, fan speed, drum speed, types of probes…the list goes on and on. So, if you want to start roasting yourself, where do you start!? In the first half of this episode, I interview one of the world's leading roasting teachers who takes me through his published scientific research to give a clear answer. It’s as simple as 80%, 15% and 5%. And then, in the second half, I show you why roasting coffee consistently batch-after-batch is so difficult. But these problems are finally being solved with smart technologies. I visited the ROEST engineering team in Oslo and cracked open their innovative prototype P3000 roaster to show you the technology that allows anybody to roast coffee consistently and fully automatically.

The world’s farming soils are deteriorating quickly. Conventional coffee farming where plants are grown using agrochemicals allowed farmers to reap huge harvests these last 70 years. But these agrochemicals have been at the expense of soil health. I travel to Honduras to explore a potential solution: organic coffee farming. Come with me as I show you the organic farming tricks of Don Rufino, one of the region’s leading organic farmers. He nurtures the soil around his coffee trees using mountain microorganisms, a huge diversity of shade trees, attentive tree pruning, and very funky batches of homemade bug spray. The results speak for themselves: when I pick up a handful of his soil, it is moist, dense and writhing with life.

Farming coffee organically is amazing because soils are more alive, birds and insects are more plentiful, farmers avoid getting sick with agrochemicals. But, if it’s so great, why is less than 10% of the world’s coffee grown organically? The fact is, going organic is hard. Much harder than growing coffee conventionally. In this episode I show you the story of one of Central America’s most successful organic coffee cooperatives, RAOS, and the four big hurdles that stood in the way of their early founders who all dreamed of converting their farms to organic.

In the last episode, I discovered that rinsing my Chemex filter papers was a waste of time! As a result I’ve managed to claw back over seven days of my life left on earth.  But why stop there?  The coffee industry is full of elaborate ways of brewing and savouring coffee: fancy drippers, cold metal balls, “slurp-able” cupping spoons. These are very fun, but how many of them actually affect the flavour of our coffee? I fear elaborate coffee gear is wasting our time and money. They're distracting us from the existential crises in coffee that actually require all our attention now. For example, the issue of farmers who grow delicious coffees quitting the business because it’s just getting too hard.  But to figure out whether a popular new coffee tool was actually waste of time or not, I needed to think like a scientist.  This episode is the journey I went on to rewire my brain: I had to learn what good evidence looks like, what to do if I can’t find good evidence, and why it’s important to focus mostly on experimental results while resisting the allure of a compelling theory.  Please spread the word about The Science of Coffee!

For your coffee to taste its best, it’s crucial you buy fresh roasts and grind fresh.… .….Or maybe not.  When I began creating this episode, I was convinced that ‘fresh is best’. But, after delving into the science of coffee freshness, I don’t believe that anymore.  This episode goes deep into how diffusion and oxidation changes a coffee’s flavours. You’ll learn what it takes to store your coffee grounds unbelievably well. So well, that if you do it right, you will struggle to taste the difference between two month old coffee compared to those same beans freshly ground!
