But why? The barrista at an Italian bar makes hundreds of shots a week. I have never seen a mistake. Even the espresso they pump out at the bars at the huge trade shows in tiny plastic cups always seem to be right on the mark. What is the mystery? The main reason for espressi being so bad in the states is because no one is trained on how to clean the machine. Most bartenders place the gruppo (the part where the grinds go) in the dishwasher at the end of every shift. The first think I was taught 20 years ago here in Italy by a barista is to never wash a coffee machine a stove top moka or a regular machine) with soap. No soap, ever! When you use soap (and hot water too) you take off all of the lovely oils that the grindsleave behind. This is what gets the crema. When we bought our big $10 grand machine for our restaurant (12 years ago), I bought a 5 kilos of beans and started making espressi. Took quite a while (coupole of hours) but the result was a great coffee from the first day we opened. I taught all of our bartenders never to wash the gruppo, just to rinse it daily with cold water. Of course every once in a while, someone would through them in the dishwasher (a fill in bartender or the cleaning crew) so I would have to start all over again with my 5 kilo bag.
