Big Brother is watching... well maybe not big brother, but we do know Italian espresso machine part manufacturers are--with the introduction of Factory Cut Bottomless Portafilters.

This E61 Group standard bottomless or naked portafilter features a clean precision cut and chrome job where a bottom and spout once resided. This portafilter will fit any E61 group head machine from manufacturers such as Astra, Faema, Grimac, Iberital, Magister, Rancilio, V.F.A., Wega and some Brasilia models (check the bayonet orientation from the above images).

Taste the difference this Portafilter can make. Our bottomless portafilters are professionally machine milled to get the cleanest, smoothest cut possible. The Barista can watch the coffee brew right from the bottom of the filter basket and now immediately know if channeling occurs, signaling the user that a level tamp was not made, which makes this an invaluable tool for training. All true professional baristi and coffeegeeks alike should have one. Most Bottomless Portafilters will accept 21 gram triple baskets since portafilter body depth is no longer an issue. This item will come standard with a 21 gram triple basket.

This is an item that has created quite a stir in the specialty coffee hobby and trade. The Bottomless Portafilter has been referred to as Naked and Crotch-less, but what ever you call it, it is truly a revelation and an innovation and Espresso Parts brought it to you first.

Isomac and Giotto users! As the Isomac and Giotto use an E61 "style" group and the casting is slightly different than a traditional Faema E61, this may not work for you. We do not currently carry portafilters specifically for the Isomac, Elektra, Expobar or ECM, which all claim to have E61 groups, but are in fact slightly different. WE HIGHLY RECOMMEND THAT YOU MEASURE YOUR EXISTING PORTAFILTER AND COMPARE THE DIMENSIONS TO THE MEASUREMENTS PROVIDED IN THE ABOVE IMAGES. Thanks.

Caution: This particular Naked Portafilter has been produced by an espresso machine parts manufacturer, the inside is chromed all the way through and the bottom edge is very precise and can be relatively sharp.
