The Melitta was chosen because it is, as advertised, an extra fine grind - not espresso fine but still quite finely ground. If the experiment was a bust, then I wouldn't have wasted much time finding this out. It worked better than I expected even with less than fresh coffee so I ground the much fresher (roast date of 12/15/10) whole bean R.I. FTO Cannonball Espresso Blend (bottom two pictures).
I certainly agree the Brazil/Ethiopian Sidamo blend would be very nice - From R.I.: "coffees from the Jinotega region of Nicaragua, northwestern Sumatra and Sidamo in Ethiopia" - so at least part of the suggested mix is in this blend.
This was less a test of coffee rather, but instead a test of the method described compared to the results from a retail Nespresso capsule. It isn't as convenient, but it isn't terribly difficult either. If someone was a big fan of Nespresso in milk drinks then a cheaper alternative to retail would have a certain thrifty appeal.
