:: The Black, Black Oils :: (#)

  „Ensure regular backfiushing of traditional espresso machines, and take care to clean all the parts of the portafilter daily. If you have a bean-to-cup machine, put it through the cleaning cycle daily. Remember there is a range of foodsafe detergents available for weekly cleaning of the espresso equipment. In short, the oils in espresso coffee represent a double-edged sword.“

  „of water (for a double shot) at a temperature of 195-200 degrees Fahrenheit and a pressure of 9-10 bars. Portafilter baskets designed for single espresso shots seldom function properly, so I recommend using the "double basket." Ensure your grinder burrs have sharp edges to finely shave the roasted beans instead of crushing them. Grinder performance is very critical.“

It's All About Coffee

  „3 TAMPING Creating great espresso requires compacting the coffee grounds into the portafilter handle, a process called tamping. (Most machines come with a round, flat tamper with a short handle.) The proper technique: Apply about 30 pounds of pressure, then finish with a twist to polish the top of the grounds. Not sure how hard to push? Practice by pushing down on a bathroom scale with one hand.“

The Espresso Pages from Sweet Maria's: Espresso, a Definition and General

  „These machines usually come with a Null Filter - a portafilter that snaps into the coffee handle with no holes in it. That means you can put a little coffee cleaner (Cafiza ) into it, put it into the brew head, turn on the machine for 30+ seconds, and backflush! If your machine has no 3 Way Valve, no worries. Just keep the coffee handle clean by soaking it in a Cafiza solution, and remove and clean the shower screen every week or two.“
