PurpleSpoilz 58mm Bottomless (Naked) Portafilter

A Bottomless (Naked) Portafilter allows the barista to view any problems that may be present during the espresso extraction. Ideally, there will be a uniform extraction through the entire coffee cake. The use of a naked portafilter will immediately show if there are any spots that are over or under extracting. The barista can then modify their technique or possibly their tamper to achieve a better extraction. It fits any machine with a E61 group head and also is compatible with Aurora, Elektra, Isomac Millennium Faema, Futurmat, Marzocco, Vibiemme, Wega and ECM machines.
