What the… is RDT?

We discovered the Ross Droplet Technique (RDT) thanks to the legendary James Hoffman. With single dosing, we often had ground coffee everywhere after grinding (except where we wanted it). Frustrating! 😤 The culprit is static electricity. With this RDT spray, that’s a thing of the past, and we’re so excited to share it with you!

How does it work?

Spray your coffee beans with a fine mist of water. Ideally, use the Coffee Dosing Tray to spray over a bigger surface area. Then grind the beans as you normally would, and voilà! No more static. All your ground coffee goes neatly into your dosing cup or portafilter. 🎯 With nothing left behind in your grinder, you can consistently brew your favorite espresso!

There’s a reason we sell this RDT Spray

Our products are completely tailored to your (and our) needs as home baristas.

  • Simple and convenient! Twist to spray, pull out to refill. It’s that easy.
  • Quality with style: Refillable glass spray bottle that doesn’t affect taste. The holder protects the bottle in case it drops.
  • The perfect combo! With the Coffee Dosing Tray, the RDT spray becomes more effective!
