ZeroHero Espresso Tamper

Yes. While the tamper base is 58.5mm, it is specifically engineered to fit standard 58mm portafilter baskets. The slightly larger diameter helps reduce the amount of coffee grounds left on the sidewalls of the basket compared to a standard 58mm tamper.

The tamper features a collar that rests on the rim of your portafilter basket. As you press down, this collar ensures the base remains perfectly parallel to the basket, preventing uneven tamping that can lead to channeling.

No, the 30lb pressure is fixed. This calibration is designed to provide a consistent, industry-standard force every time you tamp, removing the guesswork and variability often found in manual tamping.

This tamper is designed specifically for standard, non-pressurized bottomless portafilters. It will likely not fit or function correctly with pressurized baskets, which typically have different internal dimensions.

You can wipe the stainless steel base with a clean, dry cloth after each use. If it needs a deeper clean, use a damp cloth with mild soap, but ensure it is completely dry before using it on your coffee grounds.
