The coffee-houses that sprang up across Europe, starting around 1650, functioned as information exchanges for writers, politicians, businessmen and scientists. Like today’s websites, weblogs and discussion boards, coffee-houses were lively and often unreliable sources of information that typically specialised in a particular topic or political viewpoint. They were outlets for a stream of newsletters, pamphlets, advertising free-sheets and broadsides. Depending on the interests of their customers, some coffee-houses displayed commodity prices, share prices and shipping lists, whereas others provided foreign newsletters filled with coffee-house gossip from abroad.
Rumours, news and gossip were also carried between coffee-houses by their patrons, and sometimes runners would flit from one coffee-house to another within a particular city to report major events such as the outbreak of a war or the death of a head of state. Coffee-houses were centres of scientific education, literary and philosophical speculation, commercial innovation and, sometimes, political fermentation. Collectively, Europe’s interconnected web of coffee-houses formed the internet of the Enlightenment era.
The great soberer
Coffee, the drink that fuelled this network, originated in the highlands of Ethiopia, where its beans were originally chewed rather than infused for their invigorating effects. It spread into the Islamic world during the 15th century, where it was embraced as an alternative to alcohol, which was forbidden (officially, at least) to Muslims. Coffee came to be regarded as the very antithesis of alcoholic drinks, sobering rather than intoxicating, stimulating mental activity and heightening perception rather than dulling the senses.
This reputation accompanied coffee as it spread into western Europe during the 17th century, at first as a medicine.
