    Why was decaf so bad for so long, and why is good decaf still so hard to find? In the final episode of The Coffee Producer Toolkit, we go inside a decaffeination plant in Veracruz, Mexico, to see what it actually takes to pull the caffeine out of a coffee bean, and why a farm needs around 50 hectares before single-origin decaf starts to make sense.

    Part of The Coffee Producer Toolkit, a series made in collaboration with Lucia Solis, it will help you understand coffee farming better than most professionals you'll meet at a trade show.

    Each episode takes one part of the farming business — agronomy, processing, fermentation, storage, quality, sales — and lays out what the best farms are actually doing.

    This episode takes you through the basics of good water for coffee.

    To objectively assess a coffee's quality, both producer and buyer need to taste it using the same water. But whose water standards should you choose? Why do roasters often get to define what the "right" water is? What would the coffee world look like if producers set quality standards instead of roasters?

    This episode is a practical guide to tasting coffee, sample roasting and judging quality, built for small producers on a tight budget. That makes it just as useful if you’re early in your coffee journey and want to learn the basics without spending thousands on equipment, starting with a frying pan or a $30 popcorn popper.

    If you work in coffee, it reveals the obstacles producers face when they try to discuss quality on equal terms with buyers in the global north.

    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.

    Shownotes

    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.

    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?

    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.

    On a long walk through Hamburg, somewhere between the fish markets and giant cranes, you might stumble a giant bronze coffee bean looks like its crash landed from space.

    But this giant coffee bean represents a staggering fact: one in every three cups of coffee drunk in Europe has passed through Hamburg.

    In the first half of this episode, we explore the many profound ways coffee shaped one of Europe’s most important cities.

    But then the story flips because, once coffee changed Hamburg, Hamburg began to change 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.

    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.

    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.

    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”.

    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

    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.
