VST Precision Filter Baskets, 15g to 25g VST Precision Filter Baskets are what professionals reach for when they want the same result, shot after shot. Micro-machined to ±5% total hole area and individually QC-reported, every basket gives you even water distribution and reduced channelling. Available in ridgeless and ridged styles across five capacity options: 15g, 18g, 20g, 22g, and the new 25g. Looking for the 7g single basket? It's available on a separate product page. Why VST? Consistent extraction: Micro-machined holes ensure even flow and reduced channelling across all dose sizes. Versatile brewing: Designed for ristretto, normale, or lungo shots with minimal grind adjustment between styles. Universal fit: Compatible with 60mm portafilters and 58.4mm tampers. Precision manufacturing: Each basket is matched to ±5% total hole area and ships with an individual QC report. Built to last: Anti-wear construction resists fatigue from repeated pump cycling, so it holds its tolerance for years. Verified authenticity: Each basket is laser-etched with a unique 2D code linked to its factory measurements and QC data. Ridged vs ridgeless Both styles are identical in hole pattern, manufacturing tolerance, and extraction performance. The difference is purely physical: Ridged A small groove runs around the outer wall, locking into spring-loaded portafilters for easy removal and replacement. The standard choice for most commercial portafilter setups. Ridgeless A smooth outer wall with no groove. Easier to clean, and easier to tamp consistently, since there's no ridge to interfere with puck formation. Well suited to bottomless (naked) portafilters. Machine compatibility 15g, 18g, 20g: Compatible with most commercial espresso machines using standard portafilters. 22g: Fits La Marzocco, Synesso, and most Nuova Simonelli machines. Faema, La Cimbali, and Rancilio require a bottomless portafilter. 18g, 20g, 22g: Compatible with the La Marzocco SWIFT Grinder. 25g: Designed for 60mm portafilters with at least 30mm depth, such as the LM Stainless. We recommend checking the dimensions table below against your portafilter before ordering.

The ridge is a small groove around the outer wall that locks the basket into spring-loaded portafilters. Ridgeless baskets have a smooth outer wall, easier to clean and easier to tamp consistently, since there's no ridge to interfere with puck formation. Both types are identical in hole pattern and extraction quality. It's purely about portafilter compatibility and workflow preference. What size tamper do I need? All double and triple baskets (15g through 25g) use a 58.4mm tamper. The 7g single basket requires a 40.7–40.9mm tamper and is sold on a separate page. Will VST baskets fit my espresso machine? VST baskets fit 60mm portafilters. The 15g, 18g, and 20g sizes work with most commercial machines on standard portafilters. The 22g fits La Marzocco, Synesso, and most Nuova Simonelli machines directly. Faema, La Cimbali, and Rancilio need a bottomless portafilter. The 25g needs a portafilter with at least 30mm depth. Check the dimensions table above before ordering. What dose range should I use? Stick to the rated range for each basket: 14–16g for the 15g, 17–19g for the 18g, 19–21g for the 20g, 21–23g for the 22g, and 24–26g for the 25g. Staying within range ensures proper puck formation and consistent extraction. What makes VST baskets more precise than standard baskets? VST baskets are micro-machined to ±5% total hole area, for even water flow and minimal channelling. Every basket ships with an individual QC report and a laser-etched 2D code linking to its factory measurements, so you can verify the precision of your specific basket. Are VST baskets compatible with the La Marzocco SWIFT Grinder? Yes. The 18g, 20g, and 22g VST baskets are all compatible with the La Marzocco SWIFT Grinder. Can I use VST baskets for different shot styles? Yes. VST baskets are designed to perform consistently across ristretto, normale, and lungo with minimal grind adjustment required between styles. How do I verify my VST basket is genuine? Every VST basket carries a laser-etched 2D code on the basket itself. Scan it to view the factory measurements and QC report specific to your basket. What is special about the 25g basket? The 25g is the largest in the VST double/triple range. Its 727-hole pattern and 30mm height deliver up to 25% more soluble solids than the 20g model. VST's recommended recipe is 26g in, 36g out, for approximately 14% TDS and 20% extraction yield. How durable are VST baskets? VST baskets have an anti-wear structure that resists fatigue from repeated pump cycling, so they hold their tolerance through years of use in commercial and home settings.
