Coffee grinders with the ability to grind into a holder

Grinding in a holder

— the ability to grind coffee directly into the holder of an espresso machine (portafilter) without transferring it through a jar or measuring cup. This method is convenient because it minimizes coffee loss, creates less mess, and makes it easier to control dosing, especially when making espresso every day. Models with this feature typically have a support for the holder and an exit shape to ensure the grind goes directly into the basket. In practice, grinding into the holder is chosen when speed and consistency are important: grind a portion, level it, tamp it — and directly into the group.
