We swear by VST espresso baskets at every one of our coffee bars. Standard baskets that come in off the shelf espresso machines, even high end commercial models, are inherently inconsistent in their manufacturing. VST has sought to correct this by designing and manufacturing a precision basket. You will notice better coffee consistency across the board, and generally higher extraction percentages. Notable Features: • All VST Filters are warranted for ZERO defects. • 100% of holes are measured on every filter for quality control • All holes are measured for circularity, placement, square area and blocked holes • Filters are matched to +/- 5% to ensure identical group-to-group performance This basket model is the Ridgeless VST basket. You can also find the Ridged VST basket on our store.
