Great question! The 0.25mm fine mist lightly coats your coffee beans with a tiny amount of water before grinding. This moisture neutralizes the electrostatic charge that builds up during the grinding process. The result is that grounds fall cleanly into your dosing cup or portafilter instead of sticking to the burr chamber, chute, and lid. You will notice a cleaner grinder and more accurate dose weight immediately.

The 10ml capacity (approx. 0.34 fl oz) goes a surprisingly long way because you only need one or two spritzes per dose. Most home baristas find they get several weeks of daily single-dose use before a refill is needed. Simply unscrew the top and fill with filtered water. The glass interior makes it easy to see your water level at a glance.

Absolutely. The glass interior will not leach chemicals into your water over time the way some plastics can, and it will not degrade or cloud with repeated use. Paired with the aluminum exterior, the build feels premium and protects the glass from everyday bumps. It is a meaningful upgrade over disposable plastic spray bottles that crack or produce uneven mist patterns.

While it is purpose-built for the Ross Droplet Technique, plenty of baristas also use it to lightly mist the surface of a puck before tamping or to spritz a cloth for cleaning station surfaces. Its fine, controlled spray makes it handy wherever a small, precise amount of water is needed. The pocket-friendly size also makes it great for travel brew setups.

Keeping it in top shape is simple. Rinse the glass interior with warm water once a week to prevent any mineral deposits, and wipe the aluminum case with a dry cloth. Always use filtered water for refills, as hard water minerals can eventually clog the fine mist nozzle. If the spray ever feels uneven, a brief soak of the nozzle tip in warm water will restore it.

Absolutely. Every espresso machine, grinder, and accessory is packed with the same precision we put into designing them. We use reinforced boxes and protective cushioning specifically tested for coffee equipment—because a damaged tamper or chipped machine housing isn't acceptable.

In the rare event your portafilter, grinder, or machine arrives damaged, our support team will sort it immediately with a replacement or full refund. No runaround.
