FAQ

Coffee & Bakeware — FAQ

What is a bottomless portafilter?

A bottomless portafilter removes the base to expose the basket. This helps you identify uneven extraction and channeling issues.

Do I need a 3-ear portafilter?

Compatibility depends on your specific machine. Always check if your group head requires a 2-ear or 3-ear locking mechanism.

How does a puck screen help?

A puck screen distributes water evenly over the coffee grounds. It also keeps your shower screen cleaner by preventing backflow.

Can I use these with any machine?

No, portafilters are machine-specific. You must match the diameter and locking mechanism to your espresso machine model.

Why is my espresso spraying?

Spraying usually indicates channeling caused by poor puck preparation. Ensure your grind size is correct and your tamping is level.

Is stainless steel better than brass?

Stainless steel is highly durable and resistant to corrosion. It is the preferred material for high-quality espresso machine accessories.
