The Breville Bambino Plus does not grind beans. It is a semi-automatic espresso machine that comes with a pre-ground coffee funnel. If you want to use whole beans, you'll need to invest in a stand-alone coffee grinder. We recommend the Breville Smart Grinder Pro. It has 60 precise grind settings from the finest Espresso to the coarsest French Press, so you can always get the perfect grind for your preferred brewing method.
