    Introducing: Series Three of A History of Coffee

    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.   Press the ‘Subscribe’ button so you don’t miss future episodes. 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’.

    Coffee 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.    Please support my work directly at Ko-fi.com/FilterStories   Other ways you can help: Leave a 5 star rating on Spotify Follow me on Instagram and tag me in an Instagram story Write a review on Apple Podcasts Discover how I make these Filter Stories episodes by subscribing to my Substack newsletter   Go deeper into the story of quality: The original Filter Stories episode about Murray Cooper in Ecuador, Firefly Specialty Coffee Association's new Coffee Value Assessment 2004 cupping form from the Specialty Coffee Association of America SCAA Coffee Cuppers Handbook (4th edition, 2011) Kenneth Liberman's book, "Tasting Coffee: An Inquiry into Objectivity" SCA's video series on the CVA presented by Peter Giuliano     How does Perfect Moose detect what kind of milk is in the pitcher?

    Coffee 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.    Please support my work directly at Ko-fi.com/FilterStories   Other ways you can help: Leave a 5 star rating on Spotify Follow me on Instagram and tag me in an Instagram story Write a review on Apple Podcasts Discover how I make these Filter Stories episodes by subscribing to my Substack newsletter   Go deeper into the story of quality: 2004 cupping form from the Specialty Coffee Association of America SCAA Coffee Cuppers Handbook (4th edition, 2011) Cup of Excellence cupping form Kenneth Liberman's book, "Tasting Coffee: An Inquiry into Objectivity" SCA's video series on the CVA presented by Peter Giuliano     How does Perfect Moose detect what kind of milk is in the pitcher?

    Coffee 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”.   Please support my work directly at Ko-fi.com/FilterStories   Other ways you can help: Leave a 5 star rating on Spotify Follow me on Instagram and tag me in an Instagram story Write a review on Apple Podcasts Discover how I make these Filter Stories episodes by subscribing to my Substack newsletter   Go deeper into the story of quality: Specialty Coffee Association's new Coffee Value Assessment 2004 cupping form from the Specialty Coffee Association of America SCAA Coffee Cuppers Handbook (4th edition, 2011) Michael Sheridan of CQI discussing the inter-organisational politics behind the Houston Expo announcement on Lee Safar's Map It Forward podcast   How does Perfect Moose detect what kind of milk is in the pitcher?

    How 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.   I strongly recommend listening to the two episodes before this one first Getting great water for coffee, step-by-step & The two ingredients in water that ruin your coffee, and the ancient story behind them   Please spread the word about The Science of Coffee!

    The 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.   Read Marcia Bjonerud’s amazing book, Reading the Rocks     Please spread the word about The Science of Coffee!

    Getting 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.   Check my website for all the visuals mentioned in this episode, including:  SCA graph for excellent water (the “map”) Map of different water hardness across Paris My Berlin water report The nightmarish table of conversions… Results from my water tests in my Berlin studio Bottled water brands rated for their hardness and alkalinity   Please spread the word about The Science of Coffee!
