VST Precision Espresso Baskets & Refractometers

VST precision filter baskets are the benchmark for competition espresso extraction. Engineered with laser-cut holes and tight manufacturing tolerances, they reduce channeling, promote even flow, and deliver consistent brew ratios and repeatable results shot after shot. Trusted by baristas at the highest level and used in global coffee championships, VST baskets are the standard against which other baskets are measured.

With ±0.01% precision and sapphire optics, it gives you fast, reliable extraction yield and brew strength data to dial in your coffee with confidence. Used by top-tier cafes and roasters worldwide, the LAB III is the definitive tool for anyone serious about extraction quality.
