Because of all the variables in coffee and espresso production, true consistency can be a lofty goal. As a leading manufacturer of commercial espresso machines, La Marzocco knows this better than anyone, as it recognizes that trying to minimize variance makes for happier coffee drinkers. This is the reason behind the La Marzocco Strada (now branded as "Filter X") Portafilter Basket. Using laser precision, the Strada Portafilter Basket eliminates inconsistency in hole size as well as positioning.

The double basket (17g) will fit most 58mm portafilters, the triple basket (20g) will most likely require a bottomless portafilter, but please check manufacturer specifications on your machine to be sure.
