This episode explores how just a handful of cheap instruments can ensure quality is reproducible year-on-year, and the wastewater crisis poisoning rivers behind picture-perfect coffee farms.
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.

Welcome to The Coffee Producer Toolkit, a series made in collaboration with Lucia Solis.
This series 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. 
In this first episode, we cover the fundamentals of what makes a coffee farm viable. We look at how farms measure success and why so few know whether they're actually profitable.

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.

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.
