How RDT Makes Your Coffee Grinding Less Messy:

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.

The 50ml capacity may seem small but with around 0.1ml of liquid exiting every spray you will only be refilling your spray bottle after every 500 sprays. You can even use this RDT bottle as an espresso spray bottle.

We wrote an entire blog post article on RDT and how it effects your coffee, you can read it here.

Can I use RDT for my coffee grinder?

It is important to note that you should double check that your grinder is using burrs that are coated and suitable to withstand small amounts of water otherwise you run the risk of rusting your burrs or causing damage to your grinder. The Comandante MK3, MK4 and C60 grinders are suitable to use this technique. So is the Timemore C3 Coffee Hand Grinder.

What water should I use for RDT?

Regular tap water is more than fine to use in the RDT spray bottle however feel free to also use distilled water if you have it available.
This RDT bottle can fit around 50ml of water, working out to be hundreds of sprays in each fill.

COFFEE GRINDERS - BARISTA BASICS

  • ELECTRIC VS HAND GRINDER?

    Electric coffee grinders are quick and easy to use and make grinding espresso particularly easy. Hand grinders on the other hand are slower and demand more work.
    But generally speaking a hand grinder that is the same price as an electric grinder will tend to perform better. This is because anything electronic and requires a motor will increase the cost of the final product.

  • GRIND SIZE DISTRIBUTION

    Grind size distribution refers to the range and consistency of particle sizes produced when your coffee is ground. A 'uniform grind size distribution' ensures that all particles are similar in size, leading to an even extraction and cleaner tasting coffee. Variations in grind size distribution can make your coffee taste muddy as some particle are extracting more than others.

  • CONICAL VS FLAT BURRS

    Conical burrs offer efficient & low-heat grinding, making them ideal for home use and are commonly found in hand grinders. Flat burrs generally provide a more uniform grind size and are commonly used in electric coffee grinders, flat burrs are favoured by professionals for their precision and consistency particularly when grinding on finer grind sizes.

  • SPECIALIST OR GENERALIST

    While some grinders can produce a range of different grind sizes it is important to know that they may not be the best quality of grind size. Depending on what types of coffee you're wanting to make, you may want to consider opting for a 'espresso grinder' or a 'filter grinder' rather than an 'all-rounder coffee grinder'
