This episode explores why 30 cents a kilo is trivial for a large farm and unaffordable for a small one, the strange power imbalance that lets roasters define quality when nobody asks a winemaker what yeast they used, and how producers can talk to buyers who think starter cultures are cheating.
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 explores why coffee is only fifteen years into a fermentation revolution that wine and bread went through millennia ago, what's actually happening inside the tank when microbes multiply into billions on their own, and why farmers who used to ferment as fast as possible are now trying to do the opposite.
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.
