a grinder will be essential too. All I've got here is a hand-held electric grinder for brewed coffee.
I couldn't disagree with Chris more on this subject. The only way to have real espresso is to actually have an espresso machine. The pressure of 8.5-9.5 bar is what really defines the pressurized fusion that is so different than other brewing methods. Having said that, it is very difficult to grind correctly for a proper extraction without a good grinder. .
Well if price is an issue, I just may have the solution for you, we have a few machines, the good thing about it is depending on which model you can actually get it for free, only downside is you have to commit to the espresso for a 7month to a year depends on the machine, however you can just out right purchase the machine.I know we have a particular one Racillio, that is $100 cheaper than I have been seeing them. I have a few home machines myself The starbucks Barista, and the Delonghi, my next one I think is the Briel, or Rancillo.. Let me know if I can help you.. http://www.bod.intlcn.org
