FAQ

This portafilter is designed for 54mm group heads, specifically compatible with Breville Barista Express, Barista Pro, Barista Touch, Bambino Plus, Infuser, and Duo-Temp Pro models.
A bottomless portafilter allows you to observe the extraction process in real-time. It is an essential tool for diagnosing channeling, uneven tamping, or grind size inconsistencies, as you can see exactly how the coffee flows through the basket.
Yes, this unit includes a stainless steel 54mm filter basket designed to fit the portafilter head perfectly.
Often, yes. Because bottomless portafilters are more sensitive to puck preparation, you may find that you need to dial in your grind size more precisely. If you experience 'spritzing' or uneven flow, it is usually a sign that your grind is too coarse or your distribution needs improvement.
After each use, rinse the basket with hot water to remove coffee oils. For a deeper clean, soak the metal head in a solution of espresso machine detergent and hot water. Avoid soaking the wooden or plastic handle in water to prevent damage to the finish.
