Transform your espresso workflow with the Introvert Step-Down Portafilter Basket - a 58mm basket engineered with a 49mm extraction zone to optimise puck density, flow control and flavour balance. This innovative “step-down” design deepens the coffee bed and concentrates the extraction area, producing richer, more stable shots with improved resistance and fewer inconsistencies. It’s a precision tool designed for baristas and enthusiasts seeking the next evolution in espresso geometry.
CNC-machined from a solid block of 304 stainless steel, this basket delivers precision unmatched by stamped alternatives. The perfectly straight walls and sharply defined edges promote consistent flow, while the thickened base minimises flex during extraction - even at pressures up to 9 bar. Its robust build offers exceptional corrosion resistance and long-term durability, ensuring reliable performance for years to come.
The narrowed 49mm internal diameter allows for a taller, more compact puck while maintaining your existing 58mm portafilter setup. This configuration creates a more even pressure gradient through the grounds, reducing the risk of channelling and enhancing clarity in every cup. Whether you’re experimenting with light roasts or pursuing high-extraction shots, the Introvert Step-Down Basket brings new depth and sweetness to your espresso.
