The portafilter is the handle tool that contains the basket that baristas use to pack coffee grounds and attached to the espresso machine to brew coffee.

Also referred to as the braccio, it is one of the most important elements of making a proper espresso and the variety of coffee beverages associated with it.

To ensure that espresso are brewed exactly as how the cafe desires, line markings are often carved into the basket as measuring indicator so that coffee grounds fill up to the line.

High end cafes and bars are known to customize portafilters for identity and self-indulgence.
