What is RDT?
- RDT stands for "Ross Droplet Technique" in the coffee industry.
- RDT is a method used for grinding coffee beans that involves spraying a small amount of water onto the beans' surface before grinding. This technique helps eliminate static electricity, improving grinding efficiency and consistency in coffee grounds.
- Australian barista Ross Quail invented the RDT technique. 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.
How to Use
- Add beans to your bean tray or container.
- Twist to reveal the nozzle.
- Lightly spray once or twice over the beans.
- Grind as usual; enjoy smoother, cleaner results
