An elegant and stylish RDT Spray Bottle for a mess-free brewing experience. Coined by David Ross circa. 2005, the RDT (Ross Droplet Technique) is an easy way to reduce static and retention build up in your grinder, simply by adding a few drops of water onto your coffee beans prior to grinding. Our beautiful RDT Spray Bottle features an airless vacuum pump which delivers an ultra-fine layer of mist for an even and complete coverage. It also means you can spray from any angle, even upside-down. Refilling is a breeze - gently push the inner disc back down with a chopstick and you're ready to go. Crafted from durable PP plastic, it holds 30ml water and is finished in a luxurious matte black which elevates any coffee bar.
