New 25 gram baskets fit La Marzocco stainless steel portafilters, and most bottomless portafilters.
NOTE: Not all spouted portafilters are deep enough to hold the 18 grams and up insert baskets! If you are unsure if it will fit in yours, please contact the vendor you purchased your machine from.
Experience uniform extractions across all groups all the time - permanently. The VST Precision Insert Basket is the essential espresso filter for those in search of the ultimate cup.
The VST baskets deliver consistent extraction performance over a wide range of concentration with reduced sediment. It's designed to extract properly and expertly amongst most bottomless portafilters, including Rancillio, La Cimbali, La Marzocco, Nuova Simonelli, Quick Mill, Izzo, Rocket, Giotto, Isomac, Vibieme, and more. Each insert basket is uniquely coded for manufacturing QC and product authenticity.
The VST baskets were specially created with holes that were fabricated using a new micro-machine and finishing process. Each and every hole on every single basket was measured for the minimum and maximum range limits on area and diameter to a precision of +/- 30 µm. They were also calculated for circularity, placement, square area and any blocked holes before being considered fit for sale and fitted for Baristas. The hole pattern is centered to +/- 1.0 mm and placement is oriented for uniform extraction throughout the entire puck.
The VST Insert Basket was specifically designed to stand the test of time. The wide outlet angle prevents the filters from clogging and the anti-wear design ensures uniform performance for life of product. The structural integrity has been improved, able to withstand deflection from pump cycling without any premature fatigue failures.
Each insert basket is marked with a very unique 2-D bar-code to ensure true authenticity and performance. The 2-D bar-code stores the factory measurements, the quality reports, and even image data.
The Standard Ridged basket has an indented ring near the top; this ring, called the ridge, is what presses against the spring to hold the basket in the portafilter. The Ridgeless basket is held in by tension and is the basket of choice by the leading baristas in the country.
