Frequently Asked Questions

Q: What is RDT and how does the spray bottle help with coffee grinding?

A: RDT stands for the Ross Droplet Technique. Adding one or two tiny spritzes of water to your coffee beans before grinding significantly reduces static electricity build-up. This means fewer coffee grounds clinging to your grinder chute or flying out of your portafilter, resulting in a cleaner, more precise dose every time you grind.

Q: Is the ceramic dosing cup safe for food contact?

A: Yes, the ceramic dosing cup is food-contact safe. Its smooth, non-porous ceramic surface does not absorb odours or flavours, making it hygienic and easy to clean — simply rinse or wipe after each use.

Q: What size grinder or portafilter is this dosing cup compatible with?

A: The ceramic dosing vessel is designed as a universal single-dose measuring tray suitable for most home espresso grinders and portafilters. Its open bowl shape makes it easy to funnel your measured beans directly into your grinder's hopper or basket.

Q: How much water does the RDT spray bottle hold?

A: The spray bottle has a 9.5ml capacity, which is the ideal size for controlled, fine misting. This small volume is intentional — just one or two light sprays is all you need, and the compact bottle fits neatly on any coffee station without taking up space.
