The Coffee Producer Toolkit #3: Fermentation

Support the show on Patreon In this third episode, we give you a practical manual to take control of your fermentations and improve your farm's profitability.  We start with the basics — what is actually happening inside your tank, where the microbes come from, and why your coffee is going to ferment whether you want it to or not.  Then we go through five ways commercial microbes can make you money: consistency batch to batch, long fermentations you can run safely, lifting the score of your worst cherries rather than your best, clearing bottlenecks in your wet mill, and extending your coffee's shelf life.  We cover what a well-run fermentation actually looks like — the cleaning, the monitoring, the record-keeping — with a step-by-step blue-barrel protocol for smaller farms and guidance on when to move to tanks. We also look at the investment sums needed for commercial yeasts and how to justify them.  And we finish with the difficult questions — the environmental worries, whether using a starter culture is the same as adulterating your coffee, and how to talk about all of this with buyers who may view commercial microbes with suspicion.
