10p? based on p I think you're in the UK? what kinda coffee is that?here a 3rd wave coffee costs around 42-50 CHF for a kilo and you need 18g for an espresso, so 0.756-0.9 CHF per espresso if I calculate 0 for amortization of equipment.

I've never done this arithmetic before. With a massively inefficient usage of a french-press, I get something like three cups of coffee from a press and perhaps 7 fillings of the press from a bag from my local store. That coffee is $6 USD when it's on sale and $8 when it's not.

Neglecting the cost of the $20 press, the water, the kettle, the rinse-water, the mug, and the heating of the water, that's about $0.33 USD / cup?

I was just using a small number for effect, but it's closer to 30p usually for Americano/Filter coffee equivalent. Point remains the same.
