Ready to up your home espresso game? This bottomless (or naked) portafilter is a must-have tool for serious coffee lovers. It's made specifically for 54mm Breville machines like the Barista Express (BES870XL), Barista Pro (BES878), Barista Touch (BES880), and the older BES840XL. Being bottomless means you can see the espresso extraction directly – this lets you diagnose problems like channeling or uneven tamping, so you can dial in the perfect shot. It's crafted from food-grade 304 stainless steel with a real walnut wood handle for a comfortable, heat-resistant grip. It's durable and built to last. A quick note: if your espresso sprays everywhere, it's usually due to grind size, tamping, or distribution, not the portafilter itself. This tool helps you fix those issues and pull beautiful, cafe-quality shots at home.
