• Getting great water for coffee, step-by-step. Part 2: How to measure and treat your water

  Water massively impacts your coffee’s flavours. But most of us struggle to fix our water because water science is confusing…   …until now! In this special collaboration with Lucia Solis (Making Coffee podcast), I guide her through the two most important concepts you need to understand to get great-tasting water for coffee: hardness and alkalinity.   We go step-by-step through: • Why these concepts matter for coffee flavour and equipment • How to test your water at home • How to fix it, depending on what you’re working with   These aren’t one of my usual narrative episodes—they’re a straightforward, practical guide to help you take control of your water.   By the end of these episodes, you’ll be able to say: “I know what good water for coffee is and how to get it”.   I hope it helps you as much as it helped Lucia.   Check my website for all the visuals mentioned in this episode, including:  SCA graph for excellent water (the “map”) Map of different water hardness across Paris My Berlin water report The nightmarish table of conversions… Results from my water tests in my Berlin studio Bottled water brands rated for their hardness and alkalinity   Please spread the word about The Science of Coffee!

• Farm to port: why specialty costs more

  Every time we open a bag of beautiful specialty coffee — like Erick Bravo’s from Finca El Chaferote in Huila, Colombia — we’re drinking something that’s been on a long journey.   And I mean long! Over 1500 kilometers north up and down the Andes mountain range, a distance more than twice the height of France.   Along the way, it passes through dozens of hands, machines, and decisions. We follow it through muddy mountain sides, dusty dry mills, and hurricane-battered coastal warehouses — places where all kinds of things can go wrong. A leaky roof. An overly aggressive polishing machine. Or even theft.   But here’s the mystery: getting Erick’s coffee to port costs 50% more than sending a commodity coffee through the same route.   Why?   That question led me deep into Colombia’s coffee supply chains — and what I found changed how I think about the real cost of treating coffee with care.     Please spread the word about The Science of Coffee!

• Why one Colombian farmer chose specialty, and the other walked away

  I travel to Colombia’s Huila region to answer a question that’s puzzled me for years: if specialty coffee pays more, is better for the environment, and brews tastier cups—why don’t more farmers grow it?   I speak with two producers in the same region whose choices couldn’t be more different. One stakes his future on specialty. The other opts out.   Their decisions come down to more than passion or a hard work ethic. Instead, I uncover two  starting conditions—often invisible to us buyers—that strongly shape whether a farmer chooses specialty at all.   If we want to see more speciality coffee grown, we need to bring down the barriers to specialty. But first we need to understand what those barriers really are.   The answers might surprise you. They surprised me.   Please spread the word about The Science of Coffee!

• The hard business of selling beautiful coffee, part 2

  Volume. Cheap. Lame flavours. This is the traditional way of growing coffee in Brazil, and almost every farm does it this way.    But what if you wanted to produce beautiful, distinctive flavours instead—and make a living from it?   In this episode, we travel to Fazenda Paraíso in Minas Gerais, Brazil, where farmer Vicente Pereira and his daughter are on a steep learning curve finding buyers for their beautiful coffees.    Part 2 explores what it looks like for a small Brazilian farm to find better buyers, and the challenge of achieving pricing power.    Behind every beautiful coffee is a family story like this, but it’s a story we rarely get to see close up.    Let’s take a closer look.     Please spread the word about The Science of Coffee!
