1, Dolce Gusto Americano Capsule. $9 for 16 pods in Pakn Save. 10 grams of coffee for each. DG suggests to extract 230ml, that is too weak for most kiwi. I think 160ml is good, not too strong like a real expresso but pretty much long black like. So the cost is $0.56 per cup (160ml).
2, Typical supermarket ground coffee such as Robert Harris or Jeds. Price is around $6 per bag as 200 grams. Using a 350ml Bodum plunger you will need to pour at least 25g (Bodum suggests 21g) so the coffee is not too weak, because it's not a pressured extraction system. Also, for a 350ml plunger you will typically get 320ml of coffee, that is 2x160ml. So the cost is $0.375.
So, the capsule coffee system, in this case the Dolce Gusto, is only 49% more expensive than a plunger for a typical 160ml cup of long black. That probably is much lower than many of us would think.
