London’s coffee craze began in 1652 when Pasqua Rosée, the Greek servant of a coffee-loving British Levant merchant, opened London’s first coffeehouse (or rather, coffee shack) against the stone wall of St Michael’s churchyard in a labyrinth of alleys off Cornhill. Coffee was a smash hit; within a couple of years, Pasqua was selling over 600 dishes of coffee a day to the horror of the local tavern keepers. For anyone who’s ever tried seventeenth-century style coffee, this can come as something of a shock — unless, that is, you like your brew “black as hell, strong as death, sweet as love”, as an old Turkish proverb recommends, and shot through with grit.
