VST Precision Espresso Baskets & Refractometers
VST is a US manufacturer of precision espresso filter baskets, engineered with laser-cut holes and tight manufacturing tolerances to reduce channelling and give even flow, consistent brew ratios, and repeatable shots. They're used in global coffee championships and are a common upgrade in professional espresso setups. Ozone is the official UK distributor for VST, stocking ridged and ridgeless VST baskets from 15g to 25g, plus a double-pack 22g option for high-volume use. We also stock the VST LAB Coffee III Refractometer for those who want to take their analysis further. It gives lab-grade measurement of Total Dissolved Solids (TDS) in both espresso and brewed coffee, with ±0.01% precision and sapphire optics, fast and reliable data for dialling in extraction yield and brew strength. Syringe filters, required for accurate espresso measurement, are stocked alongside it. Ozone can supply VST wholesale to cafés and training facilities.
