- RDT stands for "Ross Droplet Technique" in the coffee industry.
- RDT is a method used when grinding coffee beans by spraying a small amount of water onto the surface of the beans before grinding. This technique helps eliminate static electricity, improving grinding efficiency and consistency in coffee grounds.
- The RDT technique was invented by Australian barista Ross Quail. By applying a fine mist of water to the beans, static electricity is reduced, allowing for smoother grinding. This process minimizes coffee dust and uneven particle sizes, ultimately enhancing extraction efficiency and quality.
- To perform RDT, place the coffee beans in a container and evenly spray a small amount of water over them. Gently stir to ensure even distribution, then wait for the surface moisture to evaporate before grinding.
- It is important to control the amount of water used—excess moisture can affect the flavor and quality of the coffee. Additionally, RDT is mainly suitable for flat burr or blade grinders and is not recommended for conical burr grinders.
