This espresso grinder funnel with a diameter of 58 mm is designed to optimise your coffee preparation. By placing the funnel on your portafilter, it ensures a more controlled and even distribution of the freshly ground coffee, which minimises waste and unevenness. This helps prevent clumping and allows for a more uniform tamping of the coffee puck, which is essential for optimal extraction and a rich flavour experience in your espresso. With its low profile of 5 mm, this funnel provides precise dosing and is an ideal espresso accessory for both home baristas and professionals using 58mm portafilters, including popular Rocket Espresso grinders and machines. An essential tool for anyone looking to improve the quality of their espresso brewing.
