If you want to get pedantic, I think a Nespresso would fail the Istituto Nazionale Espresso Italiano standard - espressoitaliano.org :)
But really I disqualify it because Nespresso simply does not look or taste like an espresso. The crema is always a bit pale and it lacks in concentration of suspended and dissolved solids. They later being important if you want to make a milk based drink that tastes of coffee.
