  • We Built This City…On Coffee: Hamburg and the making of Europe's coffee trade
    Jan 5 2026

    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.

    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’.

  • Introducing: Series Three of A History of Coffee
    Dec 29 2025

    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.

  • Coffee Quality, Part 3: When the “quality” myth hits the farm
    Dec 8 2025

    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.
