Know before you buy
This portafilter is specifically engineered for Rocket Espresso machines equipped with an E61 group head. While it may physically fit other E61-style machines, we recommend verifying your machine's specific group head dimensions to ensure a proper seal.
No, the Rocket Bottomless Portafilter is sold as the handle and body assembly only. You will need to use the double-shot filter basket that came with your machine or purchase a compatible aftermarket basket separately.
A bottomless portafilter exposes the underside of the filter basket, allowing you to see the espresso as it forms. This provides immediate visual feedback on your puck preparation, making it much easier to identify and correct issues like channeling or uneven distribution.
No, the handle on the Rocket Bottomless Portafilter is fixed and not designed to be removed. It is crafted from durable stainless steel to match the body for a cohesive, long-lasting build.
No, this portafilter is not dishwasher safe. We recommend cleaning it by hand with warm water and a mild detergent to preserve the finish and integrity of the materials.
