MHW-3BOMBER RDT spray bottle - 10 ml - less static when grinding

The MHW-3BOMBER RDT spray bottle (SB6559) is a 10 ml mister for the Ross Droplet Technique: one or two light sprays of water on your beans before grinding help reduce static. RDT is a general barista technique that works on whole beans, not on ground coffee.

How the MHW-3BOMBER RDT spray bottle works

The MHW-3BOMBER RDT spray bottle has a hidden nozzle: twist clockwise to open it, then press to spray a fine, even mist. Twist anticlockwise and the nozzle is closed and shielded from dust. Every part comes apart for cleaning, and the glass reservoir is removable and refillable with drinking water.

Using the RDT spray bottle

Use the RDT spray bottle only if your grinder's manufacturer allows RDT, and only on the dose you are about to grind, never on beans in the hopper.

1. Weigh the beans into a cup, for example on the MHW-3BOMBER Cube Mini 3.0 Pro.
2. Twist the nozzle open and give one or two light sprays.
3. Gently shake or stir the beans.
4. Grind as usual and twist the nozzle closed.

Keep the water to a minimum: wet beans can affect the taste and cake in the grinder.
