Why does the modern workday run on coffee?
A stimulant adopted by mystics to stay awake for prayer became the fuel of offices, empires and plantations.

The goats that would not sleep
The story everyone tells starts with a goatherd named Kaldi, who noticed his animals leaping about after eating the red cherries of a certain shrub. It is a good story. It is also almost certainly a fabrication: it first appears in print in Rome in 1671, in a treatise by the Maronite scholar Antoine Faustus Nairon, more than two centuries after people were demonstrably already drinking coffee. Kaldi tells us nothing about coffee and a great deal about how Europeans liked their origins: pastoral, accidental, innocent.

The first reliable cup
The plant is Ethiopian. The drink is Yemeni. The earliest credible evidence of coffee being brewed and drunk comes from the Sufi communities of fifteenth-century Yemen, where it moved through the port of Mocha. Before that we have plants and no cups. This gap matters, because almost every popular account collapses the two, treating the botanical origin and the culinary invention as one event. They are separated by an unknown number of centuries and by a border.

A drink for staying awake with God
Coffee entered history as a religious technology. Sufi orders drank it during dhikr, the night-long ceremonies of repeated remembrance, precisely because it postponed sleep. The Arabic qahwa had previously named wine; applying it to the new drink was itself an argument about what kind of thing this was. Every later use of coffee inherits this original one. It was adopted to extend the working hours of the devout, and it has been extending someone's working hours ever since.
Mecca, 1511 · 4/10
The first ban
In 1511 the market inspector of Mecca, Kha'ir Beg, convened a panel of jurists and had coffee prohibited. The stated grounds were intoxication and innovation. The practical grounds were the rooms: men were gathering in them, at night, outside the mosque, and talking. The ban was overturned within two years by the sultan in Cairo. It sets the pattern for the next two centuries. Authorities almost never object to the drink. They object to the venue.

Schools of the wise
By the middle of the sixteenth century Istanbul had coffeehouses, and Ottoman writers were calling them mekteb-i irfan, schools of knowledge. They were among the first urban spaces in the Islamic world where men of different ranks sat for hours without a religious or commercial reason to be there. The coffeehouse is the actual invention here, not the beverage. Coffee is simply the licit substance around which an unprecedented kind of room could legally form.

The penny university
London's first coffeehouse opened in St Michael's Alley in 1652, run by Pasqua Rosee, a servant from the Levant trade. Within fifty years the city had hundreds. Fellows of the Royal Society dissected specimens in them. Marine underwriters gathered at Lloyd's until the gathering became the institution. The nickname penny university described the entry price and the promise: for a penny, admission to a conversation you had no birthright to join.

The claim this journey will not make
You will often read that coffee sobered up an inebriated Europe and thereby produced the Enlightenment. It is a wonderful story and the evidence for it is thin. Brian Cowan and others have shown that beer consumption did not collapse, that coffeehouses were as associated with rumour and speculation as with reason, and that the sobriety narrative was largely built by coffeehouse proprietors advertising themselves. Coffee did not cause the Enlightenment. It furnished it with somewhere to sit.
Saint-Domingue, 1780s · 8/10
What the cup cost
European demand could not be met by Yemen, so Europeans took the plant. The Dutch established coffee in Java, the French in Saint-Domingue. By the 1780s that single French colony supplied a large share of the world's coffee, produced by enslaved people under conditions that killed them faster than they could be replaced. The drink that stood for free discussion in London was, in the same decades, an engine of the Atlantic slave economy. Both facts are the history of coffee.
United States, 1952 · 9/10
The invention of the coffee break
The phrase coffee break was popularised by a 1952 advertising campaign from the Pan-American Coffee Bureau, whose slogan told workers to give themselves one. Employers adopted it because rested workers produced more, and it was written into union contracts through the 1950s. The mystics drank to stay awake for God. The clerks drank to stay awake for the firm. The chemistry is identical and the beneficiary has changed.

Two billion cups
Somewhere around two billion cups are drunk each day. The pattern that began in a Yemeni prayer hall has not changed shape: a mild stimulant is used to hold back sleep so that the hours can be extended, and the extension serves whoever the hours belong to. It is worth asking, over the next one, who that is in your case.
