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!

• The hard business of selling beautiful coffee, part 1

  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 1 unravels the hidden structures of Brazil’s coffee industry: how prices are set, why it’s so hard to create a specialty-focused farm, and why Vicente's farm is unsustainable if he sells his coffee the traditional way.    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!

• The Speed of Heat: How to roast more coffee, faster!

  To roast coffee faster, you need to turn up the heat….right?   No!    In this episode, we explore the three powerful methods of heat transfer that revolutionised roasting. We’ll journey from humble beginnings—when roasting three kilos took half an hour—to machines that now roast hundreds of kilos of coffee in the time it takes you to boil a kettle.    But beans roasted at lightning speed look strange, and taste… well, you’ll find out. Join us as we test-drive an industrial tangential roaster where first crack remind me of fireworks crackers.    We also see the whale-sized roaster so massive it’s worth you a Guinness World Record.    We have the technology today to roast coffee faster than ever, so why aren’t we all roasting at recording-breaking speeds?   ---------------   Please spread the word about The Science of Coffee!
