Producer Toolkit: Quality Assurance, Pt 2 - The basics of good water for coffee
This episode takes you through the basics of good water for coffee. To objectively assess a coffee's quality, both producer and buyer need to taste it using the same water. But whose water standards should you choose? Why do roasters often get to define what the "right" water is? What would the coffee world look like if producers set quality standards instead of roasters? 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: Quality Assurance, Pt 1 - A practical guide to tasting and roasting coffee
This episode is a practical guide to tasting coffee, sample roasting and judging quality, built for small producers on a tight budget. That makes it just as useful if you’re early in your coffee journey and want to learn the basics without spending thousands on equipment, starting with a frying pan or a $30 popcorn popper. If you work in coffee, it reveals the obstacles producers face when they try to discuss quality on equal terms with buyers in the global north. 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: Price, Pt 1 - How the commodity '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.

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.
