S7 Ep 3Surrogates: Anything but the coffee

What happens when coffee disappears? This is not a thought experiment! It’s happened many times in history: War, blockades, tariffs, ideology, health panics, sanctions, supply shocks. When coffee is not around, people still need something warm, comforting, and familiar. And throughout history, people have reached for coffee surrogates: roasted plants and grains engineered to look like coffee…but do they actually taste like coffee? In this episode, Jonathan and James time-travel by taste testing a truly alarming number of coffee substitutes. Spoiler: you will hear a lot of spitting! Which leads to the bigger question: can anything actually replace coffee—or will we always come crawling back? Please spread the word about A History of Coffee!

S7 Ep 2Mother Coffee: The history and heritage of Ethiopia's wild coffee forests

Most coffee is grown on vast plantations using machines, pesticides and fertilisers. But in Ethiopia, coffee grows wild in humid forests surrounded by birds. And that wild coffee matters more than most of us realise. It is the genetic ‘library’ we can turn to find new varieties to help us keep coffee thriving in the face of climate change. But the communities who live alongside them and have safeguarded this genetic treasure often don’t earn enough from coffee to make preservation the obvious economic choice. Could a great story be the answer to earn higher premiums for these communities? Could that story be that all the coffee we drink today can actually be traced back to a single “mother tree” in Ethiopia? This episode is about the history of coffee in Ethiopia, how far back the evidence goes, what counts as evidence, and what we should celebrate (and pay for) when we buy “wild” Ethiopian coffee today.

S7 Ep 1We Built This City…On Coffee: Hamburg and the making of Europe's coffee trade

On a long walk through Hamburg, somewhere between the fish markets and giant cranes, you might stumble a giant bronze coffee bean looks like its crash landed from space. But this giant coffee bean represents a staggering fact: one in every three cups of coffee drunk in Europe has passed through Hamburg. In the first half of this episode, we explore the many profound ways coffee shaped one of Europe’s most important cities. But then the story flips because, once coffee changed Hamburg, Hamburg began to change coffee.

Introducing: Series Three of A History of Coffee

trailer

We’re back with more stories about the tiny psychoactive seed that changed the world and continues to shape our lives today. Is it possible to follow the story not just to Ethiopia, not just to a single town, but all the way back to one tree? We’ll uncover the uncomfortable history of Guatemala — a story about who inherited the rich volcanic soil, and who was forced to work it. We explore what happens when our worst nightmare comes true: coffee disappears from the shelves. What did people brew instead? Was any of it actually drinkable? And we tell the story of how coffee can shape the massive port city of Hamburg, and how Hamburg then went on to shape the global coffee world. 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.

S6 Ep 15Coffee Quality, Part 3: When the “quality” myth hits the farm

For twenty years, the 2004 cupping form profoundly shaped the specialty coffee world. But on the hillsides of coffee farms, some of the form’s byproducts have been disadvantaging producers. In this episode, we follow two producers whose lives collided with the myth of universal quality. These stories reveal how a single idea of “quality” can close doors for the people with the least power in the supply chain. The new coffee evaluation form, the CVA, is still young, and with any luck it will keep evolving. I hope for a form that can empower even the smallest producers.

S6 Ep 14Coffee Quality, Part 2: How “quality” became a myth

If you ask two specialty professionals what makes a high-quality coffee, you’ll likely get a surprisingly consistent answer: clean, sweet, juicy, bright. To an outsider, they would be forgiven for thinking coffee quality is universally defined. But the truth is more sober. In this episode, we examine how a simple cupping form helped create a universal idea of quality. We then look at the evidence that, in fact, it’s just the personal preferences of a small group of people masquerading as universal quality.

S6 Ep 13Coffee Quality, Part 1: The birth of specialty coffee flavours

For the longest time, coffees were dull and bitter. But then a small group of pioneers changed the world. In this episode, we travel back to the 1960s and ’70s to meet the trailblazers who realised coffees could taste distinctive: sweeter, brighter, cleaner. We discover how their personal preferences became a movement, then a form, and eventually a global definition of “quality”.

S6 Ep 12How specialty coffee woke up to water’s role in flavour

For the longest time, the coffee community only cared about water’s impact ruining espresso machine boilers and kettles. But what about water’s impact on coffee flavour? In this episode, I tell the story of how the specialty coffee community came to understand water chemistry: the pioneering work of the computational chemist Christopher Hendon and British roaster Maxwell Colonna-Dashwood, the genesis of the SCA’s Water Quality Handbook, and where we are today understanding the impact of minerals on our water.

S6 Ep 11The two ingredients in water that ruin your coffee, and the ancient story behind them

550 million years ago, earth was perfect. We had perfect water for coffee AND we were living in a vegetarian paradise! But then Earth changed—violently. The planet shifted from a peaceful, plant-eating paradise to a darker, more brutal world. And in this new world, the chemistry of water was forever altered. This is the wild story of how earth-shaking forces and the spirits of long-dead critters ruin your coffees today. This story will help you remember the two invisible ingredients in your water that have a huge impact on coffee flavour and your brewing equipment: calcium and hydrogen carbonate.

S6 Ep 10Getting great water for coffee, step-by-step. Part 2: How to measure and treat your water

Water massively impacts your coffee’s flavours. But most of us struggle to fix our water because water science is confusing… …until now! In this special collaboration with Lucia Solis (Making Coffee podcast), I guide her through the two most important concepts you need to understand to get great-tasting water for coffee: hardness and alkalinity. We go step-by-step through: • Why these concepts matter for coffee flavour and equipment • How to test your water at home • How to fix it, depending on what you’re working with These aren’t one of my usual narrative episodes—they’re a straightforward, practical guide to help you take control of your water. By the end of these episodes, you’ll be able to say: “I know what good water for coffee is and how to get it”. I hope it helps you as much as it helped Lucia.

S6 Ep 8Farm to port: why specialty costs more

Every time we open a bag of beautiful specialty coffee — like Erick Bravo’s from Finca El Chaferote in Huila, Colombia — we’re drinking something that’s been on a long journey. And I mean long! Over 1500 kilometers north up and down the Andes mountain range, a distance more than twice the height of France. Along the way, it passes through dozens of hands, machines, and decisions. We follow it through muddy mountain sides, dusty dry mills, and hurricane-battered coastal warehouses — places where all kinds of things can go wrong. A leaky roof. An overly aggressive polishing machine. Or even theft. But here’s the mystery: getting Erick’s coffee to port costs 50% more than sending a commodity coffee through the same route. Why? That question led me deep into Colombia’s coffee supply chains — and what I found changed how I think about the real cost of treating coffee with care.

S6 Ep 7Why one Colombian farmer chose specialty, and the other walked away

I travel to Colombia’s Huila region to answer a question that’s puzzled me for years: if specialty coffee pays more, is better for the environment, and brews tastier cups—why don’t more farmers grow it? I speak with two producers in the same region whose choices couldn’t be more different. One stakes his future on specialty. The other opts out. Their decisions come down to more than passion or a hard work ethic. Instead, I uncover two starting conditions—often invisible to us buyers—that strongly shape whether a farmer chooses specialty at all. If we want to see more speciality coffee grown, we need to bring down the barriers to specialty. But first we need to understand what those barriers really are. The answers might surprise you. They surprised me. Please spread the word about The Science of Coffee!

Volume. Cheap. Lame flavours. This is the traditional way of growing coffee in Brazil, and almost every farm does it this way. But what if you wanted to produce beautiful, distinctive flavours instead—and make a living from it? In this episode, we travel to Fazenda Paraíso in Minas Gerais, Brazil, where farmer Vicente Pereira and his daughter are on a steep learning curve finding buyers for their beautiful coffees. Part 2 explores what it looks like for a small Brazilian farm to find better buyers, and the challenge of achieving pricing power.

S6 Ep 4The Speed of Heat: How to roast more coffee, faster!

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.

S6 Ep 3Coffee Roasting: How baby plant food transforms into delicious coffee flavours

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.

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. --------------- Please spread the word about The Science of Coffee!

S6 Ep 1Hot vs Cold: The science behind temperature and taste

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. --------------- Please spread the word about The Science of Coffee!

S5 Ep 9Freshness and Grinding, Part 1: Protecting your coffee’s flavours

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!

S5 Ep 8What Is Good Science? Part 2: How to think like a scientist

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.

S5 Ep 6Organic Coffee, Part 2: Why don’t we see more organic coffee farms?

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. This story changed my understanding of farming and is now the reason I choose organic specialty coffee whenever I can. Please spread the word about The Science of Coffee!

S5 Ep 5Organic Coffee, Part 1: The magic of soil

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. Could these cultivation techniques be the answer to the coffee world’s declining soil health? Please spread the word about The Science of Coffee!

S5 Ep 4Coffee Roasting, Part 2: Roasting made easy

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. I am so impressed with these innovations, I believe they’re going to change the coffee industry. Please spread the word about The Science of Coffee!

S5 Ep 3Coffee Roasting, Part 1: How heat transforms coffee beans

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.

S5 Ep 1Smell and Taste, Part 1: How to be a better coffee taster

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!

S4 Ep 44) Just Friends? America’s love affair with coffee

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.

S4 Ep 33) Espresso Lungo: The slow road to Italy’s democratic espresso culture

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!

S4 Ep 11) It’s Just Coffee? How coffee houses changed the world

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.

Introducing: Series Two of A History of Coffee

trailer

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.

S3 Ep 66) Sonic Seasoning

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!

S3 Ep 55) Latte Foam

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. Along the way I also settle the big debate: what is the actual difference between regular Oatly and Oatly Barista Edition!? --------- Please spread the word about The Science of Coffee!

S3 Ep 44) Espresso Technology

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?

S3 Ep 33) Plant Genetics

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. But, it all depends on you, me and the coffee industry making a couple of changes right now. —--- Please spread the word about The Science of Coffee!

S3 Ep 22) Coffee Extraction

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!

S3 Ep 11) Water For Brewing Coffee

A newer, updated version of this episode is out — listen here instead! ----- 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!

S1 Ep 1Coffee’s Ticking Time Bomb

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.

S1 Ep 16) The Future of Coffee?

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.
