Coffee's long journey through ports and people

The highlands the cargo came from

The chain this page follows starts in the Yemeni highlands, and the starting point is documented at population level rather than asserted. A review chapter on the history and genetic diversity of cultivated Coffea arabica distinguishes the species' centre of origin, where wild populations have recently been recorded in South Sudan, from its centre of domestication, for which the chapter reports new genetic data from Yemen. A separate traceability study of Yemeni green coffee names the five governorates that still supply the crop — Al Mahwit, Dhamar, Ibb, Sa'dah and Sana'a — and estimates the country's smallholder coffee farmers at 150,000, describing their holdings as mountain plots worked with manual post-harvest methods.

The direction of travel is what matters for a route. Supply came from terraced smallholdings rather than from estates, so the lots entering trade began as small consignments gathered from scattered farms, and the market quarters where the drink was first sold sat downstream of that gathering. The same traceability study states that both coffee cultivation and the coffee trade began in Yemen. What the chronicle record then dates is the finished drink acquiring its own building, and the route it takes north runs through the Syrian trading cities rather than straight out of the producing highlands.

Tahtakale, 1554: a format gets its first address

The coffeehouse acquired a street address before it acquired a reputation for argument. Its earliest known premises are recorded in Istanbul in the 1550s, in the Tahtakale quarter, where the chronicle account that Eminegül Karababa and Güliz Ger's consumer-culture study traces to the historian İbrahim Peçevi names two keepers, both recent arrivals from Aleppo and Damascus. That detail is the route in miniature: the institution reaches Istanbul through the Syrian trading cities, carried by named tradesmen with a business model, rather than arriving straight from the Yemeni highlands where the plant was domesticated.

Position mattered as much as the recipe. Tahtakale sits inside the market district, a short haul from the quays where goods were landed and the covered market where they were sold, so a shop could restock beans, fuel and cups without owning a warehouse. Once beans and a rented room existed, the format could be copied by anyone with stock and premises, and copying is what turns a single address into a category of business. Within two generations the same room type appears across the Ottoman market quarters, which is why the earliest European coffeehouses open in ports that already traded with those cities.

1652 for the room, 1679 for the bathhouse

The London room can be dated against a second imported building type. The same account places the city's first Turkish bath in 1679: a building modelled on Ottoman design, with a central cold bath, alcoves holding warm baths and a sweating room, and a clientele that included both sexes on different days and a range of social classes. Two imported building types, twenty-seven years apart, on the same side of the water.

The interval between them is the clearest evidence that what moved was a format rather than only a drink. A bathhouse carries no cargo that has to be landed and roasted; it exists only if travellers can describe it — the sequence of cold plunge, warm alcove and sweating room — to a bricklayer in London. Coffee needed the same descriptive traffic plus a supply chain, which is why the commercial room arrived first. Ports that already handled Levantine goods had the merchants, the credit and the returning travellers to make the copy possible.

1675: a port city's rooms become a government problem

The political cost of the format surfaced in 1675. Charles II, according to the same account, was troubled that the rooms were being used to "spread scandalous reports concerning the conduct of his Majesty and his Ministers", and his attempt to suppress them was reversed after public opposition. Enforcement came from the centre; resistance came from the clientele, and the clientele was the reason the rooms existed.

A coffeehouse in a port city did work no harbour office did. Arrivals, cargoes, losses and prices were pooled and repeated in one room, and information of that kind carries a price, so the merchants and brokers who used the room to trade had a commercial interest in keeping the door open. The premises were also taxable businesses. Attempt, backlash, retreat — the sequence in 1675 is the pattern later regulation of the trade follows.

The state's own paper for the ban year survives in digitised form: British History Online publishes the Calendar of State Papers Domestic for Charles II, 1675–6, which calendars the domestic correspondence of those two years and is where talk inside the rooms enters the official record.

From the quay to the village counter: the 1790s

The next stage of the journey is retail rather than maritime, and it can be counted in product lines. JSTOR Daily's account of the historian Troy Bickham's work describes sugar, tea, coffee and tobacco as goods that were "once exotic" and became "ubiquitous during the long eighteenth century", pushed out by low prices, extensive credit and efficient distribution networks that carried them across what Bickham calls "the geographic and social spectrums" of Great Britain.

The evidence for that spread is a shop ledger rather than a ship's manifest. In the 1790s a village grocery in Shipton-under-Wychwood, in the Cotswolds — Anne Gomm's shop — stocked at least half a dozen types of tea, three types of coffee, several grades of tobacco, sugar, orange peel, confectionery, chocolate, and spices running from nutmeg to black pepper. Three types of coffee on one village counter is a market fact: the customer was choosing between qualities and prices instead of taking a single article off the shelf. The port is the first node in the chain, and the number of lines on a Cotswold counter measures how far downstream the chain had reached by the last decade of the eighteenth century.

What the objects record: 1838, and traffic running the other way

The material trail runs back the other way in the nineteenth century. The Victoria and Albert Museum holds Thomas Allom's watercolour "Interior of a Turkish Caffinet, Constantinople", painted in 1838 and reproduced as an etching for the Reverend Robert Walsh's Constantinople and the Scenery of the Seven Churches of Asia Minor, published in the same year; Walsh's text calls the caffinet "something more splendid", the Turk's "favourite place of indulgence" (p. 59). The museum's own record describes the type: timber-framed rooms with carved and painted rococo interiors and small fountains to cool the air in summer, where customers drank coffee, listened to music, were shaved, smoked pipes, heard storytellers or simply sat. Because the structures were wooden and Istanbul burned often, the cataloguers doubt that a single nineteenth-century rococo coffee house still stands.

The same museum holds a coffee pot made at Kütahya, an Anatolian potting town whose workshops supplied the empire's ceramic trade — a vessel record rather than a picture of a room. Set beside the 1838 watercolour, the two objects show the traffic reversed from 1652: European artists making dated images on the Ottoman side of the trade and feeding them back into European print culture, carrying the room westward to readers who would never sit in one.
