J begins the day by bringing me my morning coffee and saying, reflectively, that he wonders how many whiskey bottles a kilo of coffee would fill. This turns out to be a question of translating the weight of ground coffee to volume and not a suggestion that another breakfast beverage might be more economical. And, as usual, Google finds an answer. One pound of ground coffee equals 1.42 litres by volume. So even allowing for very finely ground coffee the volume of a kilo should be well over two litres. And, as is usual with Google, the eye strays. And so, only tangentially related, I see that “for a 1 kg bag of coffee beans you should expect to get around 120-140 cups of coffee”. Bringing to mind the punchline to an old Monty Python riddle. How is American beer like making love in a canoe? F###ing close to water. Or, as a former colleague memorably said, there is no such thing as coffee that is too strong - only men that are too weak.
