Overview
A small spray bottle for RDT, the Ross Droplet Technique: a quick mist of water on your beans before they go into the grinder.
Grinding dry beans, especially light roasts or in dry air, builds up static. Grounds cling to the grinder, scatter over the counter and clump together. A light spray on the dosed beans reduces that static, so the grind comes out cleaner, distributes more evenly and less coffee stays trapped inside the grinder.
How to use
- Fill the bottle with water
- Weigh your dose of beans
- Give the beans one or two light sprays and stir or shake
- Grind as usual
