S7 Ep 3Surrogates: 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!

S7 Ep 2Mother 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.

S7 Ep 1We Built This City…On Coffee: Hamburg and the making of Europe's coffee trade

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.

Introducing: Series Three of A History of Coffee

trailer

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.

S6 Ep 15Coffee 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.
