RDT What is Ross Droplet Technique?
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 are our Deluxe RDT Spray Bottles, featuring a unique internal pumping system that pressurises the chamber and forcing out a fine mist of water this allows you to spray horizontally or even upside down.
To refill simply unscrew the cap and nozzle, insert a chopstick to push the base down and top up with water. Reassemble the nozzle and cap and you're ready to continue using your RDT bottle!
RDT Spray Bottle Features:
- Full Matte Black
- Plastic pump nozzle & Cap
- 50ml Capacity
- Reusable, simply push the internal pump base down using a chop stick and refill with water.
Ceramic Dosing Cup
Dosing cups are incredibly handy to have around, particularly for single dose grinders.
Before you grind your coffee, it is essential to weigh out your dose of coffee and is the perfect time to integrate RDT into your coffee grinding routine.
Made from a glazed ceramic material, these dosing cups are pointed to allow your coffee beans to funnel down and slide directly into your coffee grinder without making a mess.
The Ceramic Coffee Dosing Cup can hold around 30-40g of roasted coffee beans, this is an approximation as every coffee is slightly different.

ESPRESSO
Espresso is one of the most concentrated beverages that humans can't seem to get enough of. Making perfectly dialed in coffee can be challenging at times but is not impossible, especially with the right tools.
ESPRESSO - BARISTA BASICS
-
COFFEE TO WATER RATIO
When brewing espresso you are constantly adjusting your variables to dial in your coffee. The coffee to water ratio is one of these variable.
Generally an espresso has a 1:2 Ratio but this isn't always the case and sometimes the word 'espresso' acts more as an umbrella term for coffees that are outside of this ratio.
A Lungo has a 1:3 ratio and a ristretto has a 1:1 ratio of coffee to water. -
WATER TEMPERATURE
COFFEE MACHINESBrewing espresso at different water temperatures will change how your coffee is extracted and the overall taste of your espresso.
Using a hotter water temperature will increased the body and sweetness but will have a greater chance of astringency and bitterness, while cooler water temperature will reduce bitterness, body and sweetness and can resulting in a sour, brighter espresso. -
PRESSURE FOR ESPRESSO
Pressure is a critical factor in brewing espresso, typically measured in bars. The most common pressure for extracting espresso is around 9 bars. Proper pressure ensures optimal extraction, balancing the flavours and aromas.
Adjusting your pressure throughout the one extraction is known as pressure profiling and is an entire rabbit hole in itself.

FRESHLY GROUND VS PRE-GROUND
SHOP GRINDERSGrinding your coffee right before you brew will drastically improve the taste of your coffee. The reason for this is that once you grind your coffee it has a much larger surface area and straight away starts to loose it's freshness.
