Guatemala, Part 2: Who does specialty serve?
Specialty coffee changes the story for the indigenous people of Guatemala. Coffee as a tool of oppression finally offers hope....and then something a bit more complicated.   This episode explores the tension between the values of the Mayan communities who grow coffee, and the values that drive the specialty coffee movement.   Many of the signals we typically look for in our coffees - super-specialty flavours, Fairtrade certification, “5th generation family farm” - might actually exclude coffee grown by indigenous Guatemalans.    This episode might change what kind of Guatemalan coffee you buy.    Please spread the word about A History of Coffee!   Follow us on Instagram - James (@filterstoriespodcast)  and Jonathan (@coffeehistoryjm) - and tag us in an Instagram story.    Write a review on Apple Podcasts   Leave a 5 star rating on Spotify     This free educational content for the coffee community was made possible by Mahlkönig, manufacturers of world-leading coffee grinders for 100 years for your home and cafe.      Read Jonathan’s book, Coffee: A Global History   Support James’ work directly by buying him a coffee at Ko-fi.com/FilterStories   Read James’ article on Dieseldorf, the famous German plantation owner, in Standart    Pick up a copy of Prof. Ted Fischer’s excellent book Making Better Coffee: How Maya Farmers and Third Wave Taste Makers Create Value   Follow Juan Jose on LinkedIn to keep up with his PhD on coffee farming in Jacaltenango exploring how ecology, generational memory and ritual all shape how Jacalteco farmers tend the land.      Check out Standart, the award-winning coffee magazine.

Guatemala, Part 1: Whose land is it anyway?

Guatemala, Part 1: Whose land is it anyway?
When you buy a bag of coffee labelled fifth-generation family farm, it feels like a good choice.    But in Guatemala, that label might actually be a signal for a more uncomfortable truth.   This episode explores how land has been understood, used, and eventually fought over in Guatemala for centuries between indigenous people, Europeans and those in-between.   It’s a story of what happened immediately after Guatemala won independence from Spain. This pivotal period of history gets less attention in the history books, but the suffering of the indigenous people of Guatemala gets arguably even worse.   Fair warning: it's a dark story, and it will make you think twice about what you're really choosing when you pick up a bag of coffee from Central America.     Please spread the word about A History of Coffee!   Follow us on Instagram - James (@filterstoriespodcast)  and Jonathan (@coffeehistoryjm) - and tag us in an Instagram story.    Write a review on Apple Podcasts   Leave a 5 star rating on Spotify     This free educational content for the coffee community was made possible by Mahlkönig, manufacturers of world-leading coffee grinders for 100 years for your home and cafe.      Read Jonathan’s book, Coffee: A Global History   Support James’ work directly by buying him a coffee at Ko-fi.com/FilterStories   Read James’ article on Dieseldorf, the famous German plantation owner, in Standart    Pick up a copy of Prof. Ted Fischer’s excellent book Making Better Coffee: How Maya Farmers and Third Wave Taste Makers Create Value   Follow Juan Jose on LinkedIn to keep up with his PhD on coffee farming in Jacaltenango exploring how ecology, generational memory and ritual all shape how Jacalteco farmers tend the land.    Check out Standart, the award-winning coffee magazine.

Surrogates: Anything but the coffee

Surrogates: 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!   Follow us on Instagram - James (@filterstoriespodcast)  and Jonathan (@coffeehistoryjm) - and tag us in an Instagram story.    Write a review on Apple Podcasts   Leave a 5 star rating on Spotify     This free educational content for the coffee community was made possible by Mahlkönig, manufacturers of world-leading coffee grinders for 100 years for your home and cafe.      Read Jonathan’s book, ‘Coffee: A Global History’   Support James’ work directly by buying him a coffee at Ko-fi.com/FilterStories   Read James’ article on the history of decaf technology in Standart   See Colin Smith’s amazing coffee museum at Smith’s Coffee in Hemel Hempstead, UK   Get nerdy about the intersection of AI and the occult on Karin’s Subtack, Mercurial Minutes     Do your own surrogate taste test!   Postum Atomo Orzo Fig Dandelion root Dateseed Acorn Chickpea Chicory Root Camp Coffee   Check out Standart, the award-winning coffee magazine.

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

Mother 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.     Please spread the word about A History of Coffee!   Follow us on Instagram - James (@filterstoriespodcast)  and Jonathan (@coffeehistoryjm) - and tag us in an Instagram story.    Write a review on Apple Podcasts    Leave a 5 star rating on Spotify     This free educational content for the coffee community was made possible by Mahlkönig, manufacturers of world-leading coffee grinders for 100 years for your home and cafe.    Read Jonathan’s book, ‘Coffee: A Global History’    Support James’ work directly by buying him a coffee at Ko-fi.com/FilterStories   Discover how James makes these Filter Stories episodes by subscribing to his Substack newsletter   Enjoy James’ Standart article about Avicenna and the earliest (supposed) written reference to coffee   Read the scientific paper pinpointing where wild coffee forests are in Ethiopia    Follow Solomon Tselele's work through his Facebook page   Learn more about the Ethiopian coffee ceremony on the Adventures in Coffee podcast   Series 3 of 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’.    Ethiopian forest sounds curtesy of George Vlad.

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