Unlike standard spouted portafilters, this bottomless design exposes the basket, allowing you to observe the entire extraction process in real time. This makes it an essential diagnostic tool for identifying channeling, uneven distribution, or incorrect grind size. By providing instant visual feedback, it helps you improve consistency and achieve better-tasting espresso with richer crema and balanced flavour. Constructed from durable 304 stainless steel with a premium anodized aluminum handle, the portafilter offers excellent strength, corrosion resistance, and a comfortable grip. It comes with a standard 16–18g basket, making it suitable for everyday espresso brewing. Compatible with a wide range of Breville/Sage 54mm machines, this portafilter is a valuable upgrade for both home baristas and professionals looking to elevate their espresso workflow.
