Rocket Espresso Portafilter Basket

This basket is designed for standard 58mm portafilters, which are used on most Rocket Espresso machines and many other commercial-style espresso machines. If you are using a machine with a non-standard group head size, such as a 54mm or 57mm system, this basket will not fit.

The flat bottom design promotes a more uniform puck density compared to traditional curved baskets. This helps prevent channeling and ensures that water passes through the coffee bed evenly, resulting in a more consistent and balanced extraction.

Yes, 18 grams is widely considered the industry standard for a double shot. It provides enough headspace for most medium-to-dark roast coffees, though you may need to adjust your dose slightly depending on the roast level and density of your specific beans.

Precision baskets often have a higher flow rate than stock baskets, so you may find that your shots run faster initially. You will likely need to adjust your grinder to a slightly finer setting to compensate and achieve your desired extraction time.

The 200-micron laser-cut holes are engineered to be uniform in size and placement, which minimizes the risk of uneven flow. This precision helps reduce bitterness caused by over-extraction in some areas of the puck while ensuring you don't under-extract others.
