VST filter baskets for espresso
A precision basket is a simple upgrade, because it changes how evenly water passes through the puck. VST baskets are individually checked and come with a data sheet, with the holes optically measured for consistency.
Ridged or ridgeless?
Both styles are 58mm. The ridged basket has a groove on the outer wall that helps it sit in spring-clip portafilters. The ridgeless basket has a smooth wall and suits those who find a smooth wall easier to clean and tamp. Their internal measurements are very close, so choose on fit and personal preference rather than performance.
Choosing a dose
Basket size is your target dose, and the basket needs to hold the grounds with a little room for the group's shower screen. Smaller doses suit lighter, more delicate roasts, while larger doses add body. Use a scale and adjust your grind rather than changing several things at once.
Is it worth upgrading?
Standard baskets can work well, but a precision basket removes one source of variation. It is most noticeable if you already own a good grinder and tamp consistently.
Fit and advice
If your portafilter or machine is unusual, ask first. We can check specifications with you and help you decide between ridged and ridgeless.
