The Benefits of Using the RDT Technique on Baratza Sette Grinders

by Jahasia Cooper July 12, 2019 2 min read

The Ross Droplet Technique (RDT) is an easy hack if you find that grinding your coffee beans with an electric grinder has become a messy hassle. This technique involves spraying or adding a ‘droplet’ of water to your coffee beans to reduce static-loaded coffee grinds and grind retention when single-dose grinding. For anyone who's noticed their grounds clinging to metal surfaces or flying away from the portafilter while grinding, this is a must-have. In the video below, Whole Latte Love’s resident coffee expert, Marc Buckman, demonstrates how to properly achieve this technique on Ceado and Baratza Sette Grinders.


As Marc demonstrates in the video, you can use your finger to add moisture to the coffee beans, however, we recommend using a fine mist spray bottle. Not only is it safer, but this will also ensure that your coffee beans are evenly coated with a light layer of moisture to effectively stop static when grinding coffee.

Baratza Sette grinders were built and perfected in Liechtenstein over a period of 8 years. The 30, 270, and 270Wi unit grinders represent a unique technology created with German, Austrian and Swiss cultural influences. The carefully designed grinders produce a fluffy and even distribution of coffee grinds using conical burrs. Here’s what you can expect from three of Baratza’s most popular grinders.
