Barista RDT Spray Bottle

RDT stands for Ross Droplet Technique, in summary adding a small amount of water to your dose of coffee before grinding will reduce the overall static and result in less retention in your grinder.

This method can be achieved by using a cup of water and a spoon, simply use the back of a spoon to dip into the water and then stir this wet spoon through your dose of coffee. However many people prefer using these spray bottles as they are closed off and don't risk spilling, they are refillable and dispense the perfect amount of water every time. These spray bottles in particular and made from Aluminium and coated in a matte black finish to suit all your favourite brewing equipment.

What water can I use?

Regular tap water is more than fine however if you have filtered or distilled water accessible we recommend using these.
