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 far can we go?But, before clicking play, be warned: this story gets explosive and bloody!-------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 Spotify Learn more about how Eversys espresso machines (this episode’s sponsor) produce high quality espressosListen to my A History of Coffee podcast series with Prof. Jonathan MorrisPictures of the espresso machines featured in this episodeAngelo Moriondo (1884, “Big water boiler with gnarly bits”)La Pavoni Ideale (1905, "Fire hydrant")Gaggia Tipo Classica (1947, “Lever”)Faema E61 (1961, “Retro 60s toaster”)Eversys (2022, “push button”)Want to go deeper into espresso machine technology?

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?

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!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/3yHkjcVExplore this episode’s sponsor Marco Beverage Systems SP 9 brewer and how it delivers consistent brews in the cafe (https://bit.ly/3Tgh18r)Listen to the Adventures in Coffee episode about making dramatically different brews using the Aeropress: https://bit.ly/3TghsQ7 Want more to listen to more documentary podcasts about coffee?

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!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/3yHkjcVDiscover this episode’s sponsor BWT’s water filtration products.

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/300V4jSSign up for the 2022 Barista League's High Density (free!) conference here: https://bit.ly/3BjAI78Read Stuart McCook’s excellent book, Coffee Is Not Forever: https://bit.ly/3320robAnd follow his Instagram: https://bit.ly/3sJ2OVIFollow Hansa Coffee on Instagram: https://bit.ly/3sOyLfrListen 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.
