VST Precision Filter Basket, Single Dose (7g)

VST Precision Filter Baskets are what professionals reach for when they want the same result, shot after shot, and the 7g single dose basket brings that same precision to a single shot. VST remains the only company in the world to image every hole of every filter it produces. That's what gives each basket identical extraction characteristics to every other VST basket of the same size.

Standard filter baskets typically vary by 50-200% in total open area, which makes dialling in a single-dose recipe unpredictable. VST baskets are matched to within ±5% of each other instead. With the same grind and the recommended 7g dose, you get consistent results between this basket and the larger VST sizes, so switching between a single and a double doesn't mean starting your grinder settings from scratch.

VST baskets are made from 20% thicker food-grade stainless steel than standard filters, built to resist the fatigue that comes from repeated pump cycling. The polished interior gives a clean knock-out, and the patented anti-wear design holds its tolerance for the life of the basket. It's designed to extract properly as a ristretto, normale, or lungo with little to no change in grind setting.

Why do I need a different tamper for the 7g basket?

The 7g basket has a smaller inner chamber than a standard double basket, to suit the smaller dose. The outer diameter still fits a standard 58mm portafilter, but the coffee chamber itself needs a 40.7–40.9mm tamper for even compression.

Will this basket fit my espresso machine?

The 7g basket fits most 58mm portafilters, including all La Marzocco machines, most Synesso and Nuova Simonelli models, and most E61 group heads. 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.

What makes VST baskets different from standard filter baskets?

VST 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.

Can I use the same grind setting as my double basket?

Yes. 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.

How should I clean and maintain my VST basket?

Regular 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.

What is the QC report that comes with the basket?

Each 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.

Is the 7g basket suitable for ristretto, normale, and lungo shots?

Yes. VST baskets are designed to extract properly across ristretto, normale, and lungo with little to no change in grind setting at a fixed dose.

How long will my VST basket last?

With 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.

Why choose a single dose basket over just using less coffee in a double basket?

A 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.

Are VST baskets worth it for home users?

If 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.
