Know before you buy

This portafilter is designed for machines equipped with an E61 group head. It is compatible with most Rocket Espresso models and many other brands that utilize the standard 58mm E61 group.
Yes, it includes a 21-gram filter basket, which is suitable for double shots. You can also use your existing 58mm baskets if you prefer a different capacity.
It can be less forgiving than a spouted portafilter because it exposes any flaws in your puck preparation. However, it is an excellent training tool that will quickly teach you how to achieve a consistent, high-quality extraction.
The stainless steel construction is durable and easy to maintain. Simply rinse the portafilter with hot water after each use and occasionally soak the basket in a dedicated espresso machine cleaning solution to remove coffee oil buildup.
