VST Precision Filter Basket, Ridged

These are the filters that started the modern espresso revolution.

For the barista in pursuit of perfection, VST Precision Filter Baskets are the gold standard. Engineered with unmatched precision and consistency, these filter baskets are the choice of World Barista Champions and elite cafés worldwide — the official filter basket of the 2013–2021 World Barista Championship.

Description

Each VST Precision Filter Basket is micro-machined to perfection, individually scanned and measured for hole and extraction uniformity. VST remains the only company in the world to image every hole of every filter it produces. Every filter of a given size has an identical open area to every other filter of the same size — so every shot pulls exactly as you’d expect, and exactly like every shot pulled with another VST basket. Dial in a recipe once and it holds across baskets: your 100,000th pull will be exactly the same as your first. Other baskets change total open area as they age.

Features & Benefits
