The Rocket Espresso bottomless portafilter, redesigned, is a must-have accessory for anyone chasing a better espresso on an E61 machine. Made by hand in the Rocket tradition, it removes the spout so you can watch the extraction directly from underneath the basket: you immediately see channelling, uneven tamping or distribution issues, and correct them shot after shot. The new design refines the handle and finish while keeping the universal 58 mm compatibility shared across all Rocket machines and the wider E61 world. Comes in its own box, ready to gift or store. A simple tool that, once you use it, stays on the bench for good.
