Few of us grow up drinking coffee, but once we start drinking it, even fewer of us ever stop. According to legend, the earliest such case was a ninth-century Ethiopian goatherd named Kaldi, who noticed how much energy his ruminant charges seemed to draw from eating particular red berries. After chewing a few of them himself, he experienced the first caffeine buzz in human history. Despite almost certainly never having existed, Kaldi now lends his name to a variety of coffee shops around the world, everywhere from Addis Ababa to Seoul, where I live.
His story also opens the animated TED-Ed video above, “How Humanity Got Hooked on Coffee.” We do know, explains its narrator, that “at some point before the fourteen-hundreds, in what’s now Ethiopia, people began foraging for wild coffee in the forest undergrowth.” Early on, people consumed coffee plants by drinking tea made with their leaves, eating their berries with butter and salt, and — in what proved to be the most enduring method — “drying, roasting, and simmering its cherries into an energizing elixir.” Over the years, demand for this elixir spread throughout the Ottoman Empire, and in the fullness of time made its way outward to both Asia and Europe.
In no European city did coffee catch on as aggressively as it did in London, whose coffee houses proliferated in the mid-seventeenth-century and became “social and intellectual hotbeds.” Later, “Paris’ coffee houses hosted Enlightenment figures like Diderot and Voltaire, who allegedly drank 50 cups of coffee a day.” (In fairness, it was a lot weaker back then.) Producing and transporting the ever-increasing amounts of coffee imbibed in these and other centers of human civilization required world-spanning imperial operations, which were commanded with just the degree of caution and sensitivity one might imagine.
The world’s first commercial espresso machine was showcased in Milan in 1906, a signal moment in the industrialization and mechanization of the coffee experience. By the mid-nineteen-fifties, “about 60 percent of U.S. factories incorporated coffee breaks.” More recent trends have emphasized “specialty coffees with an emphasis on quality beans and brewing methods,” as well as certification for coffee production using “minimum wage and sustainable farming.” Whatever our considerations when buying coffee, many of us have made it an irreplaceable element of our rituals both personal and professional. Not to say what we’re addicted: this is the 3,170th Open Culture post I’ve written, but only the 3,150th or so that I’ve written while drinking coffee.

From the time that a nameless genius in either Ethiopia or Yemen decided to dry, crush and strain water through a berry known for making goats nervous and jumpy, coffee has been loved and worshiped like few other beverages. Early Arab doctors proclaimed the stuff to be a miracle drug. Thoroughly caffeinated thinkers from Voltaire to Jonathan Swift to Jack Kerouac debated literature, philosophy and everything in between at coffee houses. Author Honoré Balzac even reportedly died because of excessive coffee drinking (it was either that or the syphilis.)
Johann Sebastian Bach (1685–1750) was also apparently a coffee enthusiast. So much so that he wrote a composition about the beverage. Although known mostly for his liturgical music, his Coffee Cantata (AKA Schweigt stille, plaudert nicht, BWV 211) is a rare example of a secular work by the composer. The short comic opera was written (circa 1735) for a musical ensemble called The Collegium Musicum based in a storied Zimmerman’s coffee house in Leipzig, Germany. The whole cantata seems very much to have been written with the local audience in mind.
Coffee Cantata is about a young vivacious woman named Aria who loves coffee. Her killjoy father is, of course, dead set against his daughter having any kind of caffeinated fun. So he tries to ban her from the drink. Aria bitterly complains:
Father sir, but do not be so harsh!
If I couldn’t, three times a day,
be allowed to drink my little cup of coffee,
in my anguish I will turn into
a shriveled-up roast goat.Ah! How sweet coffee tastes,
more delicious than a thousand kisses,
milder than muscatel wine.
Coffee, I have to have coffee,
and, if someone wants to pamper me,
ah, then bring me coffee as a gift!
The copywriters at Starbucks marketing department couldn’t have written it any better. Eventually, daughter and father reconcile when he agrees to have a guaranteed three cups of coffee a day written into her marriage contract. You can watch it in its entirety below, or get a quick taste above. The lyrics in German and English can be read here.

The Romans fashioned their buildings with concrete that has endured for 2,000 years. Their secret? Some researchers think it’s how the Romans heated lime. Others think it’s how they used pozzolanic material such as volcanic ash. Nowhere does coffee figure into the equation. Too bad.
Happily, researchers at the Royal Melbourne Institute of Technology (RMIT) University have discovered that “concrete can be made 30% stronger by replacing a percentage of sand with spent coffee grounds, an organic waste product produced in huge amounts that usually ends up in landfills,” writes New Atlas. Rajeev Roychand (above), the lead author of a study in the Journal of Cleaner Production, notes: “The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gasses including methane and carbon dioxide, which contribute to climate change. The inspiration for our work was to find an innovative way of using the large amounts of coffee waste in construction projects rather than going to landfills—to give coffee a ‘double shot’ at life.” If Roychand’s research findings endure, archaeologists and materials engineers might enjoy puzzling over the mysteries of coffee and concrete another two millennia from now.

It costs roughly $20,000, weighs nearly 100 pounds, and looks like a high-end microscope. Handmade in Switzerland, the MANUMENT Leva Machine makes espresso. How well does it make espresso? How do the shots taste?: According to coffee expert James Hoffmann–he’s the author of The World Atlas of Coffee–the shots have a texture that is “very enjoyable.” The texture is “silky, buttery and soft.” That verdict is sandwiched in the middle of a 20-minute review of the machine, which you can watch above.

According to many historians, the English Enlightenment may never have happened were it not for coffeehouses, the public sphere where poets, critics, philosophers, legal minds, and other intellectual gadflies regularly met to chatter about the pressing concerns of the day. And yet, writes scholar Bonnie Calhoun, “it was not for the taste of coffee that people flocked to these establishments.”
Indeed, one irate pamphleteer defined coffee, which was at this time without cream or sugar and usually watered down, as “puddle-water, and so ugly in colour and taste [sic].”
No syrupy, high-dollar Macchiatos or smooth, creamy lattes kept them coming back. Rather than the beverage, “it was the nature of the institution that caused its popularity to skyrocket during the seventeenth and eighteenth centuries.”
How, then, were proprietors to achieve economic growth? Like the owner of the first English coffee-shop did in 1652, London merchant Samuel Price deployed the time-honored tactics of the mountebank, using advertising to make all sorts of claims for coffee’s many “virtues” in order to convince consumers to drink the stuff at home. In the 1690 broadside above, writes Rebecca Onion at Slate, Price made a “litany of claims for coffee’s health benefits,” some of which “we’d recognize today and others that seem far-fetched.” In the latter category are assertions that “coffee-drinking populations didn’t get common diseases” like kidney stones or “Scurvey, Gout, Dropsie.” Coffee could also, Price claimed, improve hearing and “swooning” and was “experimentally good to prevent Miscarriage.”
Among these spurious medical benefits is listed a genuine effect of coffee—its relief of “lethargy.” Price’s other beverages—“Chocolette, and Thee or Tea”—receive much less emphasis since they didn’t require a hard sell. No one needs to be convinced of the benefits of coffee these days—indeed many of us can’t function without it. But as we sit in corporate chain cafes, glued to smartphones and laptop screens and mostly ignoring each other, our coffeehouses have become somewhat pale imitations of those vibrant Enlightenment-era establishments where, writes Calhoun, “men [though rarely women] were encouraged to engage in both verbal and written discourse with regard for wit over rank.”

According to NPR, “Caffeine is the most widely consumed drug in the world. Here in the U.S., according to a 2022 survey, more than 93% of adults consume caffeine, and of those, 75% consume caffeine at least once a day.” Given the prevalence of coffee worldwide, it pays to ask a simple question: Is coffee good for you? Above, James Hoffmann, the author of The World Atlas of Coffee, provides an overview of research examining the relationship between coffee and various dimensions of health, including the gut/microbiome, sleep, cancer, cognition, mortality and more. If you want to explore this subject more deeply, Hoffmann has created a list of the research papers reviewed here.

James Hoffmann knows something about coffee. He’s authored The World Atlas of Coffee and runs a prolific YouTube channel, where he covers everything from making coffee with the AeroPress and MokaPot, to brewing the perfect espresso and also providing basic coffee making tips & tricks. Pretty bread and butter stuff, if you can use that expression when talking about coffee. But he also covers some subjects at the margins of the coffee world–like how to develop photographs with coffee. Above, Hoffmann introduces you to Caffenol, a process whereby photographs can be developed with coffee and sometimes Vitamin C. To take a deeper dive into the subject, you’ll want to explore PetaPixel’s primer, Caffenol: A Guide to Developing B&W Film with Coffee.

No matter how much coffee you drink, you never drink the same coffee twice. Coffee-drinkers understand this instinctively, even those who only drink their coffee at home using the same beans and the same brewing process day in and day out. For even in the most controlled coffee-making conditions we can achieve in our everyday lives, variations have a way of creeping in. Endless scrutiny of those variations is all in a day’s work for someone like Matt Perger, who’s come out on or near the top of several barista championships, and who founded the online coffee-education service Barista Hustle and its associated Youtube channel.
In the channel’s most popular video by far, Perger delivers an 80-minute lecture on “advanced coffee making” at Assembly Coffee in London. After covering the adjectives used to describe the flavor of coffee in general — from “weak,” “delicate,” and “tea-like” to “luscious,” “bitter,” and “overwhelming” — he moves on to the vocabulary of extraction.
The most important stage in the coffee-making process as far as the resulting taste is concerned, extraction is accomplished by putting hot water through coffee grounds, in whichever manner and with whichever device you may choose to do it. Weaker methods of extraction result in “salty” or “vegetal” tastes, and stronger methods in “astringent” or “powdery” ones.
As in so many pursuits, the most desirable outcomes lie in the middle of the spectrum. Just how to achieve that perfectly “transparent,” “nutty,” “balanced,” and even “sweet” cup of coffee constitutes the driving professional question for Perger and baristas like him. Clearly possessed of a taste for rigor, he explains the effects of everything from the design of roasters and grinders to the techniques of brewing and pouring while citing the findings of experiments and blind taste tests — and even acknowledging when pieces of expensive coffee-making gear yield no demonstrable quantitative benefit. True coffee aficionados who have an endless appetite for this kind of talk may find themselves tempted to sign up for Barista Hustle’s online courses, but even more so to brew another cup for themselves.
