58mm Bottomless Portafilter for La Marzocco – 18g Basket Included, Anodized Aluminum (White)

Designed to fit baskets of 58mm diameter, this bottomless portafilter is compatible with many La Marzocco espresso machine models.

A bottomless portafilter (also called a naked portafilter) is the best tool for diagnosing extraction issues. With the spouts removed and the basket exposed, you can watch the whole extraction and spot channeling or uneven flow as it happens.

Made from 304 stainless steel with an aluminum alloy handle. An 18g basket is included.

• Designed for La Marzocco espresso machines (58mm group head), with an 18g double-shot basket included
• Bottomless design lets you monitor flow and diagnose channeling
• Manually lathed anodized aluminum handle for a comfortable, precise grip
• Stainless steel and anodized aluminum construction
• No bottom plate means any basket size works — single, double, or triple

Please note: Channeling and spurting are common when you first switch to a bottomless portafilter, and aren't a defect. It's your coffee telling you there's room to adjust grind size, tamping, or distribution.
