• Introducing: Season 3 of The Science of Coffee

  We’re back with another series of The Science of Coffee—and this time we’re diving even deeper into coffee’s hidden microscopic secrets!   Over the past year, narrative audio producer and coffee professional James Harper has scoured academic journals, ventured deep into coffee farms, and conducted bold tasting experiments.   Now, he’s weaving those discoveries into captivating audio stories that reveal why coffee tastes the way it does—and how we can make it taste even better.   In this new series, you’ll learn about cold brew extraction science, explore innovations in roasting, and follow the shifting business models that shape farmers’ livelihoods. You’ll also take a journey through commodity vs. specialty supply chains and examine the historical, sociological, and philosophical perspectives that define what “specialty coffee” truly means.   Press the “Subscribe” button so you don’t miss an episode! https://bit.ly/3TdDnHO   For more coffee science and behind-the-scenes content, follow James on Instagram @filterstoriespodcast. https://bit.ly/2Mlkk0O   The Science of Coffee is a spin-off series from James Harper’s documentary podcast, Filter Stories.  https://bit.ly/3ajoT5e   Season 3 is made possible by these leading coffee organizations:   The Coffee Quest | BWT | TODDY | Algrano | Probat

  Deep inside your coffee grinder, tiny changes can have massive consequences.  This episode takes you deep inside Mahlkönig’s grinders to show you how coffee is ground and the importance of particle sizes on flavour.  If you’re a home coffee lover, you could easily spend thousands of dollars on your coffee grinder. But after diving deep into the R&D of grinder manufacturing, I learned that after a certain point spending more probably won’t produce a better tasting cup of coffee for you!  --------- Please spread the word about The Science of Coffee!  Discover how I make these Filter Stories episodes by subscribing to my Substack newsletter.  Write a review on Apple Podcasts Follow me on Instagram and tag me in an Instagram story Leave a 5 star rating on Spotify Explore Mahlkönig’s range of world leading grinders, trusted by baristas globally.

• Freshness and Grinding, Part 1: Protecting your coffee’s flavours

  For your coffee to taste its best, it’s crucial you buy fresh roasts and grind fresh.… .….Or maybe not.  When I began creating this episode, I was convinced that ‘fresh is best’. But, after delving into the science of coffee freshness, I don’t believe that anymore.  This episode goes deep into how diffusion and oxidation changes a coffee’s flavours. You’ll learn what it takes to store your coffee grounds unbelievably well. So well, that if you do it right, you will struggle to taste the difference between two month old coffee compared to those same beans freshly ground! But here’s the weirdest thing: Maybe, just maybe, you will prefer old coffee more than the fresh stuff. ---------- Please spread the word about The Science of Coffee!

• What Is Good Science? Part 2: How to think like a scientist

  In the last episode, I discovered that rinsing my Chemex filter papers was a waste of time! As a result I’ve managed to claw back over seven days of my life left on earth.  But why stop there?  The coffee industry is full of elaborate ways of brewing and savouring coffee: fancy drippers, cold metal balls, “slurp-able” cupping spoons. These are very fun, but how many of them actually affect the flavour of our coffee? I fear elaborate coffee gear is wasting our time and money. They're distracting us from the existential crises in coffee that actually require all our attention now. For example, the issue of farmers who grow delicious coffees quitting the business because it’s just getting too hard.  But to figure out whether a popular new coffee tool was actually waste of time or not, I needed to think like a scientist.  This episode is the journey I went on to rewire my brain: I had to learn what good evidence looks like, what to do if I can’t find good evidence, and why it’s important to focus mostly on experimental results while resisting the allure of a compelling theory.  Please spread the word about The Science of Coffee!
