Quick Answer

A grinder knock drawer sits under your coffee grinder to catch used coffee grounds, keeping your counter clean. Use it by knocking the portafilter against the bar, then empty the drawer regularly to avoid buildup.

Why Use a Dedicated Knock Drawer Instead of a Trash Can?

A dedicated under-grinder drawer saves time and mess. Knocking directly into a trash can often scatters grounds, requires bending down, and can leave residue on the rim. A drawer designed for the job sits at the right height and contains the mess inside a removable tray.

For busy coffee shops or home baristas who make multiple drinks in a row, a knock drawer also speeds up workflow. You knock, twist, and move on without pausing to wipe the counter.

Choosing the Right Spot for Your Drawer

Place the drawer directly under your grinder's dosing area or where you normally tap out the portafilter. The drawer should be stable and not slide around when you knock. If your grinder has a dedicated platform, the drawer fits neatly underneath.

The Crem Under Grinder Knock Drawer is designed to complement CREM grinders and other similar-sized setups. Its stainless steel body adds stability and a sleek look to your station.

How to Use Your Grinder Knock Drawer in 5 Steps

  1. Position the Drawer Correctly: Place the knock drawer on a flat, stable surface directly under your grinder's exit chute or where you normally tap the portafilter. Ensure it doesn't wobble. Common mistake: placing the drawer too far away, causing grounds to miss the tray.
  2. Knock the Portafilter Firmly: After dosing and tamping, hold the portafilter horizontally and tap the basket edge against the knock bar (the padded bar inside the drawer). Use a quick, firm motion to dislodge the puck. Avoid hitting too hard—this can dent the basket or loosen the handle over time.
  3. Check for Residual Grounds: After knocking, glance at the basket. If a thin layer remains, wipe it with a dry cloth or give a second light tap. Do not knock again if the puck is gone—it wastes time and can cause wear. Leaving old grounds in the basket can make your next shot taste stale.
  4. Empty the Drawer Regularly: When the drawer is about half full, slide it out and dump the grounds into a compost bin or trash. Rinse the drawer with warm water and dry it before sliding it back. Letting grounds pile up creates a mess when you knock and can attract pests.
  5. Clean the Drawer Weekly: Remove the knock bar (if detachable) and wash the drawer with mild soap and a soft sponge. Dry thoroughly to prevent water spots on the chrome finish. Reassemble before the next use. Skipping weekly cleaning lets coffee oils build up, which can stain the stainless steel.
