Coffee 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. See for yourself Roest's innovative P3000 fully automatic roaster.

Smell and Taste, Part 2: Are you and me tasting the same flavours?

Ever wonder why you and your friends can taste the same coffee, but you can’t agree on the flavour notes? Join me as I explore this metaphysical mystery! I speak with leading scientists and ask: are the flavour receptors in your nose and mouth the same as mine? How does music and the shape of a cup affect what we taste? What about our different cultural backgrounds and language? Best of all, I put all these questions to the test in the Athen’s World of Coffee trade show.

Smell 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!This episode will help you deepen your appreciation of coffee and its delicious complexity. ---------See Marco Beverage Systems' SP9 for yourself, and discover their range of consistent and energy-efficient coffee brewers for your cafe.

4) 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.

3) 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!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!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.

2) A Lasting Stain: Haiti, Colonialism and Coffee

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.Be warned: this episode contains graphic descriptions of violence.

1) 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.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.

6) 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!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
