Big Brother is watching... Well maybe not big brother but we do know Italian espresso machine parts manufacturers are with the introduction of OEM Factory Bottomless Portafilters.

This OEM Bottomless Portafilter fits Astoria, RIO & Brasilia (NOT THE GRADISCA MODEL!) Espresso Machine Groups. The standard bottomless or naked portafilter features a clean precision cut and chrome job where a bottom and spout once resided.

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 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 coffee geeks 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 LM style triple basket (21 Gram) choose your model below.

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 EspressoParts brought it to you first.

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.
