After years of unanswered prayers from the 54mm Breville espresso enthusiasts, we here at Crema are thrilled to finally announce one of our newest creations: our custom designed 54mm dosing cup, developed to work specifically with Breville's 54mm portafilters. Not only did we create a 54mm dosing cup, but we've even designed this dosing cup with a built-in grinder activating tab, allowing it to function in direct harmony with the built-in grinder and grinder holder on the Breville Barista Express, Barista Touch and Barista Pro. Would ya look at that! Our dosing cups are made from 100% stainless steel, with the black version being coated in a non-stick food grade coating. Our dosing cup can also be used with stand-alone grinders, such as the Breville Smart Grinder Pro, and the Niche Zero. Note: For use with the Smart Grinder Pro, the portafilter holder must be removed.
