The VST Precision 25g Ridgeless Basket is the benchmark filter basket for serious espresso. Engineered with a proprietary micro-machining process, every single hole is measured for diameter, area, and circularity to a precision of ±30 microns — delivering extraction uniformity that no other basket on the market can match. Why VST? Measured precision: Every hole on every basket is individually verified for size, shape, and placement before leaving the factory Uniform extraction: Centred hole pattern oriented for even flow across the entire puck Built to last: Anti-wear design with wide outlet angles prevents clogging and ensures consistent performance for the life of the basket Authenticated: Each basket carries a unique 2D barcode storing factory QC measurements and quality data Dose & Size The 25g basket is designed for 22-26g of coffee, designed for triple baskets and high-dose specialty recipes.
