Removing the spouts exposes the underside of the basket, so channelling, spritzing and uneven extraction become visible instead of being hidden by the spouts. ## The 54mm vs 52mm question This is the detail that confuses almost everyone shopping for a La Pavoni bottomless, so it is worth being precise about what each number measures. La Pavoni's accessory page describes the Fascino as a "bottomless Black-Chrome portafilter for lever coffee machines, **54mm diameter**". La Pavoni's machine pages for the Europiccola Lusso, Professional Lusso, Stradivari Lusso and Esperto Abile all state "Filter holder internal diameter (with filter): **52 mm**". Both figures come from La Pavoni, and they are not in conflict — they are measurements of different things. The 52mm figure is explicitly the holder's **internal** diameter *with the filter in place*, i.e. the basket seat. The 54mm figure is the accessory's own stated diameter. La Pavoni does not publish the relationship between the two, so we do not assert one: what we can say firsthand is that La Pavoni ships this holder with a machine it specifies at 52mm internally, which is the fitment fact you actually need. This is the same trap the [58mm standard](/guides/58mm-is-not-one-standard/) sets, in miniature: a single number on a portafilter can describe the tamper seat, the basket body, or the holder itself, and buying on the number alone is how people end up with a part that does not seat. ## What it fits Because a portafilter locks into the **grouphead**, not into a portafilter size, this entry is keyed by group rather than by a millimetre figure — it is listed against the La Pavoni lever group, and deliberately not filed under the 54mm standard, which is Breville's proprietary format and has nothing to do with La Pavoni. The chain is entirely from La Pavoni's own pages: the Fascino page states it is for "lever coffee machines"; the Esperto Abile page lists "Standard and Fascino filter holders" among a 52mm lever machine's accessories; and the Europiccola, Professional and Stradivari Lusso pages each state "Type: Lever Espresso coffee machine" with the same 52mm internal figure. **Note on baskets:** the Fascino ships as a holder. If you are pairing it with a precision basket, IMS assigns post-millennium La Pavoni to its B60 series — see the [IMS B60 competition basket](/baskets/ims-b60-competition-2-cup-la-pavoni/), whose Ø52mm internal body matches La Pavoni's own figure. Vintage pre-millennium La Pavoni levers are a different format and are not covered here. ## Sources - https://www.lapavoni.com/en/products/domestic-machines/filter-holder-fascino-blackchrome-lever-coffee-machine - Official La Pavoni product page, read firsthand 2026-08-10.
