Why Use a Retention Bellow?

Even the best single-dose grinders can retain a small amount of ground coffee in the chute after each grind. A silicone bellow lets you dislodge those retained grounds with a gentle squeeze, ensuring you get the full dose you dialed in — essential for precision brewing. It's a small addition to your setup that makes a genuinely noticeable difference.
