Getting great water for coffee, step-by-step. Part 1: Alkalinity, hardness and why it matters

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!

Smell and Taste, Part 2: Are you and I tasting the same flavours?

Ever wonder why you and your friends can taste the same coffee, but you can’t agree on the flavour notes? Join me as I explore this metaphysical mystery! I speak with leading scientists and ask: are the flavour receptors in your nose and mouth the same as mine? How does music and the shape of a cup affect what we taste? What about our different cultural backgrounds and language? Best of all, I put all these questions to the test in the Athen’s World of Coffee trade show.

2) Coffee Extraction

How you brew your coffee dramatically affects what you taste. And I do mean dramatic! Brewing up the same bag of coffee beans can taste like a slice of heaven, or a slap in the face. So, what exactly is happening at a microscopic level when water swirls through coffee grinds? Why does boiling water extract certain flavours, while letting the kettle cool for five minutes make it taste markedly different? In this episode, we dive deep into the academic research conducted at the UC Davis Coffee Center so you can choose your flavour adventure: Do you like your coffees when they’re a sour bomb? A floral caress on the lips? A smokey drag on a pipe? Or a treacle of sweet syrup? We also explore why it can be so difficult getting the same flavours from the same beans consistently. And finally, I equip you with tools so you can begin finding your perfect brew. —--- Please spread the word about The Science of Coffee!

Coffee Quality, Part 1: The birth of specialty coffee flavours

For the longest time, coffees were dull and bitter. But then a small group of pioneers changed the world. In this episode, we travel back to the 1960s and ’70s to meet the trailblazers who realised coffees could taste distinctive: sweeter, brighter, cleaner. We discover how their personal preferences became a movement, then a form, and eventually a global definition of “quality”.

Smell and Taste, Part 1: How to be a better coffee taster

So you’ve just taken a sip of a very rare coffee, and flavours of passion fruit explode in your mouth. But here’s the thing: that flavour of passion fruit is not coming from your mouth. It’s not even coming from your nostrils. It’s being picked up behind your eyes! In this first episode of The Science of Coffee's second series, I unravel how our sense of smell and taste works to help you be a better coffee taster. I shrink us down microscopically and we dive into your tongue to show you why good black coffee tastes sweet, even though there’s no sugar in it. We then travel up into our noses and get stuck in a lot of mucus. This slime might be disgusting, but we need it to be able to smell well. And finally, with the help of tasting expert and author Mandy Naglich, I show you three effective ways you can train yourself to be a much better coffee taster without having to go on any expensive courses. The trick is to train our internal flavour prediction models! This episode will help you deepen your appreciation of coffee and its delicious complexity. --------- See Marco Beverage Systems' SP9 for yourself, and discover their range of consistent and energy-efficient coffee brewers for your cafe.

Mother Coffee: The history and heritage of Ethiopia's wild coffee forests

Most coffee is grown on vast plantations using machines, pesticides and fertilisers. But in Ethiopia, coffee grows wild in humid forests surrounded by birds. And that wild coffee matters more than most of us realise. It is the genetic ‘library’ we can turn to find new varieties to help us keep coffee thriving in the face of climate change. But the communities who live alongside them and have safeguarded this genetic treasure often don’t earn enough from coffee to make preservation the obvious economic choice. Could a great story be the answer to earn higher premiums for these communities? Could that story be that all the coffee we drink today can actually be traced back to a single “mother tree” in Ethiopia? This episode is about the history of coffee in Ethiopia, how far back the evidence goes, what counts as evidence, and what we should celebrate (and pay for) when we buy “wild” Ethiopian coffee today.

Coffee Quality, Part 3: When the “quality” myth hits the farm

For twenty years, the 2004 cupping form profoundly shaped the specialty coffee world. But on the hillsides of coffee farms, some of the form’s byproducts have been disadvantaging producers. In this episode, we follow two producers whose lives collided with the myth of universal quality. These stories reveal how a single idea of “quality” can close doors for the people with the least power in the supply chain. The new coffee evaluation form, the CVA, is still young, and with any luck it will keep evolving. I hope for a form that can empower even the smallest producers.

Coffee Quality, Part 2: How “quality” became a myth

If you ask two specialty professionals what makes a high-quality coffee, you’ll likely get a surprisingly consistent answer: clean, sweet, juicy, bright. To an outsider, they would be forgiven for thinking coffee quality is universally defined. But the truth is more sober. In this episode, we examine how a simple cupping form helped create a universal idea of quality. We then look at the evidence that, in fact, it’s just the personal preferences of a small group of people masquerading as universal quality.

We Built This City…On Coffee: Hamburg and the making of Europe's coffee trade

On a long walk through Hamburg, somewhere between the fish markets and giant cranes, you might stumble a giant bronze coffee bean looks like its crash landed from space. But this giant coffee bean represents a staggering fact: one in every three cups of coffee drunk in Europe has passed through Hamburg. In the first half of this episode, we explore the many profound ways coffee shaped one of Europe’s most important cities. But then the story flips because, once coffee changed Hamburg, Hamburg began to change coffee.
