Remember — until the mid-seventeenth century, most people in England were either slightly — or very — drunk all of the time. Drink London’s fetid river water at your own peril; most people wisely favoured watered-down ale or beer (“small beer”). The arrival of coffee, then, triggered a dawn of sobriety that laid the foundations for truly spectacular economic growth in the decades that followed as people thought clearly for the first time. The stock exchange, insurance industry, and auctioneering: all burst into life in 17th-century coffeehouses — in Jonathan’s, Lloyd’s, and Garraway’s — spawning the credit, security, and markets that facilitated the dramatic expansion of Britain’s network of global trade in Asia, Africa and America.

It’s hard to overstate how much I loved this little lesson on the history of coffeehouses: The Lost World of the London Coffeehouse
