Great question! A dosing funnel sits on top of your portafilter basket and creates a raised wall that catches every coffee particle during grinding and distribution. This means zero grounds lost over the edge, so the dose you weigh is the dose that gets extracted. The result is more consistent shot weights and significantly less cleanup between pulls.

The easiest way is to measure the inner diameter of your portafilter basket. We offer three sizes: 51mm (approx. 2 in), 54mm (approx. 2.13 in), and 58mm (approx. 2.28 in). Most commercial-style machines like the Breville Barista Express use 54mm, while many E61 group heads and prosumer machines use 58mm. Check your machine's specs or measure directly across the basket opening.

Absolutely. This funnel is crafted from food-grade 304 stainless steel, one of the most trusted alloys in kitchen and coffee equipment. It resists corrosion, does not leach flavors into your coffee, and holds up to daily use without warping or tarnishing. The non-magnetic construction also means it will not interfere with any magnetized accessories in your setup.

It depends on your workflow. The funnel is designed for easy placement and removal, so most baristas set it on the portafilter during grinding and distribution, then lift it off before tamping. Its slim profile makes this a quick one-handed motion. Some users do keep it on while tamping, but removing it gives you a cleaner lock-in to the group head.

Keeping it clean is effortless. After each session, simply rinse under warm water and wipe with a soft sponge or brush to remove any residual coffee oils. Dry it with a towel or let it air-dry. Avoid harsh abrasive cleaners, as they can dull the polished finish over time. With basic care, this funnel will stay looking and performing like new for years.

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.
