"SOMETIMES it’s hard to tell how much coffee costs, even if you know what you spent. At least that’s the case with many of the single-serve brewing machines that are soaring in popularity.
For example, the Nespresso Arpeggio costs $5.70 for 10 espresso capsules, while the Folgers Black Silk blend for a K-Cup brewed-coffee machine is $10.69 for 12 pods. But that Nespresso capsule contains 5 grams of coffee, so it costs about $51 a pound. And the Folgers, with 8 grams per capsule, works out to more than $50 a pound.
That’s even more expensive than all but the priciest coffees sold by artisanal roasters, the stuff of coffee snobs."
