## Notes

The 25g size — the deepest VST precision basket at 30.0mm, for triple-style
high-dose shots. Governance note: VST's compatibility statement for the
25/22/7g sizes names "all La Marzocco" but does **not** list Rancilio (the
15/18/20g sizes do), so this is cross-referenced only to the La Marzocco
machines. At 30mm deep it also demands enough headroom under the group — check
your machine before ordering. Does not fit 54mm machines. Verified against the
official VST store page on 2026-07-07.

  - Official VST store product page, read firsthand 2026-07-07. States verbatim: '25-g, 22-g & 7-g fits all La Marzocco and Most Synesso and Nuova Simonelli models using their standard portafilters.' The per-size table lists the 25g basket at 30.0mm height — the deepest in the VST range. 'VST Filters DO NOT fit 49, 53 or 54mm portafilters.' VST's compatibility sentence for the 25g size names La Marzocco (and Synesso/Nuova Simonelli) but NOT Rancilio, unlike the 15/18/20g sizes.
