FAQS

What is a portafilter?

A portafilter is the handle and filter basket holder used in an espresso machine. It locks into the group head and holds the coffee grounds during extraction.

What is a bottomless portafilter used for?

A bottomless portafilter lets you see the espresso flow directly from the basket. It is commonly used to check channeling, uneven extraction, grind size issues, and tamping consistency.

Is a bottomless portafilter better than a spouted portafilter?

It depends on your workflow. A bottomless portafilter is better for learning and improving extraction, while a spouted portafilter is better for a cleaner daily workflow and splitting espresso into cups.

How do I know which portafilter size I need?

Check your espresso machine model and original portafilter size. Common sizes include 51mm, 54mm, and 58mm, but fit also depends on the machine’s locking ear design.
