Producer Toolkit: Price, Pt 1 - How the C market works
This episode explores the strange world of the C market, where movements in the Brazilian currency or rebels boarding a random container ship decide the worth of a Colombian farmer's coffee. Yet specialty coffee still uses this number to price the coffees it says are anything but a commodity. 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.

Producer Toolkit: Marketing & Sales, Pt 2 - Navigating trade shows
This episode explores what a trade show actually feels like for a farmer who flew in on money his community pooled together, why a sausage dog opened a door that hundreds of cold emails couldn't, and why learning English may be a better investment for a farmer than a longer fermentation. 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.

Producer Toolkit: Fermentation, Pt 3 - Is using yeast cheating? And who decides?
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.
