58 mm Portafilter, CP6100U

About this part

A second portafilter is what lets you pull back to back without knocking one out first.

Espresso accessories are model specific, and the two portafilter sizes are not interchangeable: 51 mm fits the compact machines, 58 mm the retro and CP6100U bodies. A second portafilter is the small luxury that lets you pull two shots back to back, and a pitcher with a narrow spout is the difference between latte art and a splash. What each part does to the shot is set out in Espresso at Home: Pressure, Grind and Milk.

Everything else on this shelf is on espresso accessories, and the machines these parts belong to are in Neretva kitchen appliances.
