Deep inside your coffee grinder, tiny changes can have massive consequences. This episode takes you deep inside Mahlkönig’s grinders to show you how coffee is ground and the importance of particle sizes on flavour. If you’re a home coffee lover, you could easily spend thousands of dollars on your coffee grinder. But after diving deep into the R&D of grinder manufacturing, I learned that after a certain point spending more probably won’t produce a better tasting cup of coffee for you! ---------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!But here’s the weirdest thing: Maybe, just maybe, you will prefer old coffee more than the fresh stuff.----------Please spread the word about The Science of Coffee!Discover how I make these Filter Stories episodes by subscribing to my Substack newsletter.

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.

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.

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!Discover how I make these Filter Stories episodes by subscribing to my Substack newsletter!

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!Follow me on Instagram and tag me in an Instagram storyWrite a review on Apple PodcastsLeave a 5 star rating on SpotifyDive deeper into the science of roastingExplore ROEST’s innovative products for the coffee industry.Learn more from Morten Münchow and his coffee roasting coursesRead Morten’s paper in collaboration with the University of Copenhagen on Roasting Conditions and Coffee FlavourConnect with my very knowledgeable guestsSverre Simonsen - LinkedInCallum Gilmour - LinkedInVeronica Balduc - LinkedInMorten Münchow - Coffee Mind websiteScott Rao - InstagramThe Science of Coffee is made possible by these leading coffee organisationsBWT Water and MoreMarco Beverage SystemsROESTSustainable HarvestMahlkönigThe Science of Coffee is a spin-off series from James Harper's documentary podcast Filter Stories

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.

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.

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.

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.

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.A History of Coffee is a collaboration between documentary maker James Harper of the Filter Stories coffee podcast and Jonathan Morris, Professor of History and author of ‘Coffee: A Global History’. -----------Don't miss future episodes by pressing the 'Subscribe' or 'Follow' button in your podcast playerPlease spread the word about A History of Coffee!Follow us on Instagram - Jonathan (@coffeehistoryjm) and James (@filterstoriespodcast) - and tag us in an Instagram story.

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!Follow me on Instagram and tag me in an Instagram storyWrite a review on Apple PodcastsLeave a 5 star rating on SpotifyExplore the technology behind Fiorenzato’s AllGround home coffee grinderGet more involved in coffee science!Buy Brita Folmer’s The Craft & Science of CoffeeRead the Specialty Coffee Association's 25 Magazine for cutting edge insights into coffee science, business and sustainability, including Charles Spence’s article on sonic seasoningPartner with the Coffee Science FoundationExplore Felipe Reinoso Carvalho’s sonic research, including Diego Campos’ winning World Barista Championship routineApply to study at the UC Davis Coffee CentreDo an online course with ZHAW’s Coffee Excellence CentreSubscribe to Barista Hustle and complete their online coffee coursesBecome a member of the Barista Guild, Coffee Roaster’s Guild, Coffee Technicians Guild and attend their events!Connect with my very knowledgeable guestsCharles Spence - Academic profileFabiana Carvalho - InstagramJanice Wang - LinkedInFelipe Reinoso Carvalho - LinkedInChahan Yeretzian - LinkedInBill Ristenpart - Academic profilePeter Giuliano - LinkedInJenn Rugolo - LinkedInGiulia Bagato - LinkedInDenis Girardi - LinkedInThe Science of Coffee is made possible by these leading coffee organisationsBWT Water and MoreMarco Beverage SystemsTraboccaEversysOatlyFiorenzato

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.

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 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!Follow me on Instagram and tag me in an Instagram story - https://bit.ly/2Mlkk0OWrite a review on Apple Podcasts - https://apple.co/3sf87MVLeave a 5 star rating on Spotify - https://spoti.fi/3yHkjcVLearn more about how Trabocca, this episode’s sponsor, works with coffee farmers: https://bit.ly/3Tjn8bVSupport the work of World Coffee Research: https://bit.ly/3VtyoV6Become a member of Kew Gardens: https://bit.ly/3yFZ8b0Find some of Alvans Mutero’s (https://bit.ly/3T0NHTy) and Thiriku’s (https://bit.ly/3CCxHQJ) coffee to taste for yourselfLearn more about cloning coffee plants on my other podcast, Adventures in Coffee - https://bit.ly/3EFBmzGWant to listen to more documentary podcasts about coffee?
