Yes, this basket is designed to fit standard 58mm portafilters. However, we recommend checking your specific machine's portafilter depth, as some bottomless or specialized portafilters may have clearance limitations.

While 18g is the optimal dose for this basket, you can typically adjust by +/- 1g depending on your coffee roast and grind size. Dosing significantly outside this range may impact the extraction quality and headspace required for a balanced shot.

This basket features a precision-engineered hole pattern designed to promote more uniform water distribution. This helps minimize channeling, which is a common issue with standard stock baskets that often have less consistent hole placement.

Yes, because this is a 58mm basket, you should use a 58mm or 58.5mm tamper. A 58.5mm tamper is often preferred with precision baskets to ensure a snug fit and reduce the amount of coffee grounds left on the sidewalls.

No, this is a non-pressurized (or 'precision') filter basket. It is designed for use with standard espresso machines and requires a proper grind size to create the necessary resistance for extraction.
