{"title":"VST Precision Espresso Baskets \u0026 Refractometers","description":"\u003cp\u003eVST 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.\u003c\/p\u003e \u003cp\u003eWe 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.\u003c\/p\u003e \u003cp\u003eOzone can supply VST wholesale to cafés and training facilities.

Freshly brewed espresso contains two things that compromise refractometer accuracy: fine suspended solids that reflect light rather than refracting it, producing erratic readings, and dissolved CO2 that actively reduces the refractive index of your sample, causing TDS readings to come in lower than the true value. VST engineered these multi-media filters to tackle both problems simultaneously - clarifying the sample and allowing trapped CO2 to escape - so your measurements meet VST's own ±0.01% precision specification.\u003c\/p\u003e\n\u003cp\u003eWhile designed with espresso in mind, they're equally useful for filter coffee brewed through perforated metal or woven mesh filters such as the AeroPress with a metal disc or reusable pour-over filters. Particularly valuable for benchmarking and troubleshooting filter basket performance across single, double, and triple baskets, or comparing consistency across multiple machines.

Whether you're dialling in a new single origin, training staff on extraction principles, or simply chasing that perfect cup, this fourth-generation refractometer delivers laboratory-grade precision in a handheld device built for the demands of commercial coffee environments. For over 15 years, VST refractometers have empowered baristas, roasters, and researchers with data they can trust, and this latest iteration represents the pinnacle of that development.\u003c\/p\u003e\n\u003cp\u003eBy measuring Total Dissolved Solids (TDS) in your coffee or espresso, you gain objective insight into what's actually happening during extraction. The TDS information, along with your brewing recipe and final beverage weight, can be used to calculate and plot extraction yield, giving you the data needed to troubleshoot underextracted sourness or overextracted bitterness with confidence rather than guesswork. Combined with VST's CoffeeTools software, it lets baristas and roasters map extraction yield, fine-tune brews in real time, and achieve the flavour profile they love consistently.\u003c\/p\u003e\n\u003cp\u003eThe VST refractometer is the global standard for competitions, R\u0026amp;D labs, and quality-focused cafés, having served as the official tool at the World Brewers Cup, World Cup Tasters, and World Barista Championship from 2012 to 2022. It's the standard against which all other coffee refractometers are compared. For roasteries like ours, it's an invaluable tool for quality control and recipe development, and we're pleased to make it available to fellow coffee professionals and enthusiasts who want to bring the same rigour to their brewing.\u003c\/p\u003e\n\u003c!-- Section 2: Technical Specifications --\u003e\n\u003cdiv class=\"product-specifications\"\u003e\n\u003ch1\u003e\u003cstrong\u003eTechnical Specifications\u003c\/strong\u003e\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTDS Measurement Range:\u003c\/strong\u003e 0.00% to 20.00% (auto-ranging between coffee and espresso scales)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision:\u003c\/strong\u003e ±0.01%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (Coffee Range 0.00-4.99%):\u003c\/strong\u003e ±0.03%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAccuracy (Espresso Range 5.00-20.00%):\u003c\/strong\u003e ±0.05%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptical System:\u003c\/strong\u003e Advanced 1024-element detector array with sapphire optics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Compensation:\u003c\/strong\u003e Automatic, 15°C to 40°C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplay:\u003c\/strong\u003e 24-character backlit LCD, two-line readout\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSample Well:\u003c\/strong\u003e Stainless steel with evaporation cover and ambient light shield\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Time:\u003c\/strong\u003e 2-3 seconds (automatically averages multiple readings)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLanguage Options:\u003c\/strong\u003e English, Spanish, German, French, Russian\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e Two AAA batteries (4,000+ measurements per set)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Rubberised silicone armour jacket for durability\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalibration:\u003c\/strong\u003e Smart Zero-Set software using distilled water\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertification:\u003c\/strong\u003e NIST Traceable Reference Standards certificate included\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Manufacture:\u003c\/strong\u003e USA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSoftware Compatibility:\u003c\/strong\u003e Works with VST CoffeeTools for Windows, macOS, iOS, and Android (software sold separately)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch1\u003e\u003cstrong\u003eWhat's Included\u003c\/strong\u003e\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003eVST LAB Coffee III Refractometer with integrated auto-ranging Coffee and Espresso TDS scales\u003c\/li\u003e\n\u003cli\u003eGrey rubberised silicone armour jacket\u003c\/li\u003e\n\u003cli\u003ePipettes (10 pieces)\u003c\/li\u003e\n\u003cli\u003eCleaning pads (10 pieces)\u003c\/li\u003e\n\u003cli\u003eSyringe filter kit (50 filters, 5 syringes) for espresso and metal-filtered coffee samples (\u003ca href=\"https:\/\/ozonecoffee.surf\/products\/vst-syringe-filters\" title=\"VST Syringe Filter available from Ozone Coffee Roasters\" rel=\"noopener\" target=\"_blank\"\u003eadditional filters available separately\u003c\/a\u003e)\u003c\/li\u003e\n\u003cli\u003eNIST Traceable Quality Assurance Certificate\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eVST Software Links\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/itunes.apple.com\/app\/mojotogo\/id351660247?mt=8\" title=\"[EXTERNAL] Download VST CoffeeTools™ software for iPhone\" target=\"_blank\"\u003eVST CoffeeTools™ for iPhone\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/itunes.apple.com\/us\/app\/mojotogo-pro\/id580506126?ls=1\u0026amp;mt=8\" title=\"[EXTERNAL] Download VST CoffeeTools™ software for iPad\" target=\"_blank\"\u003eVST CoffeeTools™ for iPad\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/play.google.com\/store\/apps\/details?id=com.vstapps.android.coffeetools\" title=\"[EXTERNAL] Download VST CoffeeTools™ software for ANDROID\" target=\"_blank\"\u003eVST CoffeeTools™ for ANDROID\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c!-- Section 3: FAQs --\u003e\n\u003cdiv class=\"product-faqs\"\u003e\n\u003ch1\u003e\u003cstrong\u003eFrequently Asked Questions\u003c\/strong\u003e\u003c\/h1\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat is TDS and why does it matter for coffee brewing?\u003c\/h3\u003e\n\u003cp\u003eTDS stands for Total Dissolved Solids and represents the percentage of your brewed coffee that consists of dissolved coffee compounds rather than water. The TDS value is a measure of coffee strength: a stronger coffee has a higher TDS percentage, while a thinner one has a correspondingly lower value. Studies have determined that most people prefer their brewed coffee with a finished concentration of 1.15% to 1.35% TDS for filter coffee, while espresso typically sits around 9% to 10% TDS.

It's designed to extract properly as a ristretto, normale, or lungo with little to no change in grind setting.\u003c\/p\u003e\n\u003ch1\u003e\u003cstrong\u003eTechnical specifications\u003c\/strong\u003e\u003c\/h1\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDose Capacity:\u003c\/strong\u003e 7g (±1g recommended dosing range)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOuter Diameter:\u003c\/strong\u003e 60mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInner Diameter:\u003c\/strong\u003e 58.7mm (at rim)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight:\u003c\/strong\u003e 28mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRecommended Tamper Size:\u003c\/strong\u003e 40.7–40.9mm (smaller inner chamber requires a dedicated tamper)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Food-grade stainless steel (300 series)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e 20% thicker than standard filters, with reinforced structural integrity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Precision:\u003c\/strong\u003e 100% of holes measured to ±20µm for diameter, circularity, and placement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOpen Area Tolerance:\u003c\/strong\u003e Matched to ±5% total square hole area across all baskets\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Pattern Centring:\u003c\/strong\u003e ±1.0mm, oriented for uniform extraction throughout the puck\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterior Finish:\u003c\/strong\u003e Highly polished for easy puck release\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStyle:\u003c\/strong\u003e Standard ridged\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSerialisation:\u003c\/strong\u003e Unique 2D code referencing individual QC data and factory measurements\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 1 year, zero-defect guarantee\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Certifications:\u003c\/strong\u003e RoHS, ECHA REACH, EU General (German, Italian, French), US FDA\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePatent Protection:\u003c\/strong\u003e Protected by US patents\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMachine Compatibility:\u003c\/strong\u003e Fits all La Marzocco, most Synesso, and Nuova Simonelli models using standard portafilters.

Check your portafilter has at least 28mm of depth before ordering. If you're not sure, a bottomless portafilter will fit any VST basket size.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eWhat makes VST baskets different from standard filter baskets?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eVST remains the only company in the world to image every hole of every filter it produces, so every basket of a given size has the same open area as every other basket of that size. Standard baskets can vary by 50-200% in open area, which is why identical doses and grind settings on different baskets can still pull very differently.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eCan I use the same grind setting as my double basket?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eYes. That consistency across sizes is one of the main reasons to use VST. With the same grind and dose, you should get a similar result and a similar shot time, roughly 30 seconds, whether you're pulling a 7g single or a 15g double, so switching between the two through the day doesn't mean resetting your grinder.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eHow should I clean and maintain my VST basket?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eRegular backflushing and a soak in espresso machine cleaning solution will keep it in good condition. The polished interior and wide outlet angle help prevent clogging, and the anti-wear design keeps the holes at their original dimensions over time. Avoid anything abrasive, which can damage the polished surface.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eWhat is the QC report that comes with the basket?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eEach VST basket carries a unique 2D serial code linked to its own quality control report: the factory measurements, quality data, and imaging record for that specific basket, so you can verify it meets VST's tolerances.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eIs the 7g basket suitable for ristretto, normale, and lungo shots?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eYes. VST baskets are designed to extract properly across ristretto, normale, and lungo with little to no change in grind setting at a fixed dose.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eHow long will my VST basket last?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eWith proper care, VST baskets are built to last for years. Other baskets can change their open area as they wear, but VST's anti-wear design and reinforced construction are built to hold their tolerance for the life of the basket, backed by a one-year, zero-defect warranty.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eWhy choose a single dose basket over just using less coffee in a double basket?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eA reduced dose in a standard double basket leaves too much headspace between the coffee and the shower screen, which leads to channelling and uneven extraction. The 7g basket's smaller chamber is sized to match the dose, so the puck forms properly and the water distributes evenly.\u003c\/dd\u003e\n\u003cdt style=\"margin-top: 24px; margin-bottom: 6px; font-weight: bold; font-style: normal; text-decoration: none;\"\u003eAre VST baskets worth it for home users?\u003c\/dt\u003e\n\u003cdd style=\"margin: 0 0 20px 0;\"\u003eIf consistency matters to you, yes. VST baskets are trusted by World Barista Champions, top roasters, and equipment manufacturers, and that same consistency carries over to a home setup. Once you've dialled in your recipe, every shot pulls the same way, which removes one of the more frustrating variables in home espresso.\u003c\/dd\u003e\n\u003c\/dl\u003e","brand":"VST","offers":[{"title":"Default Title","offer_id":41685704245301,"sku":"VST (7)","price":35.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0023\/1572\/products\/Image-2_485836b3-ff02-4076-99d5-6638289516c8.jpg?v=1653903255"}],"url":"https:\/\/ozonecoffee.surf\/collections\/brewing-kit-vst.oembed","provider":"Ozone Coffee UK","version":"1.0","type":"link"}
