Breville Portafilter

This 58mm naked portafilter is designed exclusively for the Breville BES990, BES980, and BES920 models. It will not fit other Breville machines that use different portafilter sizes, so please verify your model number before purchasing.

A bottomless, or naked, portafilter allows you to see the espresso extraction in real-time as it leaves the basket. This immediate visual feedback helps you identify issues with your grind size, tamping technique, or distribution, making it an essential tool for dialing in your shots.

If your puck preparation is uneven, you may experience some spraying or channeling, which can be messy. However, this is actually a benefit; it highlights exactly where your technique needs improvement, allowing you to refine your dosing and distribution for a cleaner, more consistent extraction.

Yes, this accessory is crafted from durable stainless steel, matching the build quality and professional feel of the original components included with your Breville machine.

You generally do not need to change your grind size solely because of the portafilter itself. However, because the naked portafilter exposes extraction flaws, you may find that you need to adjust your grind or dose to achieve the perfect flow rate that you couldn't see before.
