VST Precision 18g Ridgeless Filter Basket 58 mm

Looking to get more sweetness and depth from your espresso? VST Precision Baskets offer improved consistency and extraction due to their uniquely rigorous design and manufacturing process. Available in 18g baskets for your 58mm bottomless portafilters. 

Unlike many others, VST baskets have holes across the basket's entire bottom surface, allowing water to flow evenly through the entire bed of coffee. The precision-cut holes help reduce obstructions during extraction, greatly reducing channeling - making for a more reliable and less messy experience.

Every basket is micro-machined and carefully inspected during finishing. All the holes are uniform in size and distribution. Ridged baskets have a ridge near the top of the basket which keeps the basket more firmly locked into your portafilter – some choose ridgeless to ensure the most even possible flow

• VST's precision filters deliver consistent extraction performance over a wide range of concentration with reduced sediment
• Designed to extract properly as a ristretto, normale or lungo with minimal or no change in grind setting at a fixed dose
• Filters are matched for total square area to +/- 5% to ensure identical performance
  (typical variances of standard filters range from 50-200% of nominal open square area)
• All VST Filters are WARRANTED for ONE-YEAR and for ZERO DEFECTS
• Holes are 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 µm (individual QC report provided with every filter)
• All holes are measured for circularity, placement, square area and blocked holes
• Hole pattern is centered to +/- 1.0 mm and placement is oriented for uniform extraction throughout the entire puck
• Wide outlet angle to prevent filters from clogging, patented anti-wear design ensures uniform performance for life of product
• Improved structural integrity, will withstand deflection from pump cycling without premature fatigue failures (see VST Warranty)
