Dreamfarm Grindenstein Knock Box

The Grindenstein measures 4.0 inches by 4.3 inches. While it is designed to tuck onto most standard drip trays, it is best to measure your machine's tray depth and width before purchasing to ensure a comfortable fit.

The knock bar is integrated into the design for durability, but the entire unit is top-rack dishwasher safe. This makes cleaning straightforward without needing to disassemble any parts.

The Grindenstein features a durable, sturdy construction with a shock-absorbing design. While it is compact, its weight and build quality are intended to stay put during normal use, though placing it on a non-slip mat can provide extra stability if you have a very slick countertop.

The Grindenstein is built to be robust and withstand the repeated impact of knocking out portafilters. It is designed for longevity and daily use, so it resists the typical wear and tear you would expect from a coffee accessory.

While it is specifically engineered for espresso pucks, its compact size and durable build make it a handy receptacle for other small kitchen scraps, like tea bags or loose tea leaves, if you need a secondary countertop bin.
