Wall-mounted manual grinder: 20 g hopper, glass cup

How it mounts and works

The listing describes a strong metal backboard that secures the grinder to the wall and keeps it steady while you turn the crank. Beans go into a wooden hopper that holds up to 20 g. The ground coffee falls into a transparent glass cup, so you can see how much you have before you stop.

The burr is described as a cast iron conical burr. The seller says it gives even grounds, though no burr size or material treatment is given.

Grind range

Coarseness adjusts from coarse to fine, and the listing names espresso, drip coffee, French press and cold brew as suitable methods. It does not state the number of settings or how far each step moves, so espresso users have nothing to judge precision by.

A 20 g hopper is roughly one or two cups of filter coffee. For a pot of cafetière for several people you would refill and grind more than once.

Fitting and cleaning

Because it mounts on the wall, you need a sound surface and suitable fixings. The listing does not say whether screws or plugs are supplied, so check before installing on plasterboard or tiles.

The seller describes it as quick to clean. The glass cup can be washed, and the wooden hopper should be kept dry.

Wood and cast iron age well when kept dry, so wipe the burr area with a dry brush rather than rinsing it under the tap.

Compared with the other grinders

The FOOSKOO vintage mill shares the traditional look but sits on the worktop and weighs about 5 kg. The 1Zpresso K-Ultra is a precision grinder with stated 20 micron steps and a larger 35 to 40 g catch cup. The wall-mounted grinder makes most sense when space and style matter more than exact adjustment.
