RDT Coffee Spray Bottle – 50ml

A simple addition to your coffee routine for less static and less mess.

This refillable 50ml RDT spray bottle is ideal for the Ross Droplet Technique (RDT): lightly misting whole coffee beans with water immediately before grinding to help reduce static, clumping and grounds sticking to your grinder or dosing cup.

Its clear body makes it easy to check the water level, while the compact design fits neatly alongside your coffee setup.

Features

• 50ml capacity: convenient for daily use without taking up much space.
• Clear body: see when it’s time for a refill.
• Protective cap: keeps the spray nozzle covered between uses.

How to use

1. Weigh your coffee beans using a coffee scale, then place them in a dosing cup or small container.
2. Apply a light mist of water, using only enough to lightly moisten the surface of the beans.
3. Gently shake or stir to distribute the moisture, then grind immediately.

Use sparingly: avoid soaking the beans or allowing water to pool in the container. Never spray water directly into the grinder. Follow your grinder manufacturer’s guidance on using RDT.
