VST Basket Ridgeless



VST's new precision filters deliver consistent extraction performance over a wide range of concentrations with reduced sediment.

Designed to extract properly as a ristretto, normal, or lungo with minimal or no change in grind setting at a fixed dose with holes specifically fabricated using a new micro-machine and finishing process. 100% of holes are measured on every filter for min/max range limits on area and diameter to a precision of +/- 20 and all holes are measured for circularity, placement, square area, and blocked holes. The hole pattern is centered to +/- 1.0 mm and placement is oriented for uniform extraction throughout the entire puck. 

Ridgeless, or unridged baskets, have smooth walls and as a result, generally require a stronger spring to ensure they stay in place when knocking out used coffee pucks and its wide outlet angle to prevent filters from clogging, anti-wear design ensures uniform performance for the life of the product.
