When designing their new portafilter, the team of Weber Workshops looked beyond what was already out there. They recreated the portafilter out of a single piece of stainless steel for an optimal extraction geometry. No more removable basket, unmatched extraction geometry, improved thermal stability; a giant leap for espresso. Use it, rinse it, wipe it, with no other routine maintenance for better tasting, higher extraction yield espresso.

The Unifilter is made from a solid piece of forged, machined, and hand-polished Stainless 304 material. All of the holes are individually laser-ablated and go right up to the vertical wall edge, giving a true 58.5mm puck from top to bottom. Made for 18g to 22g shots (and higher or lower with use or elimination of puck screen), but 20g at a medium roast is a good estimate of dose size.
All handles have a solid stainless steel core to give them heft and longevity. This version is covered by a cored-out piece of solid teak wood sanded and finished with a German non-VOC oil.

Due to how they are manufactured, typical 58mm baskets have angled side walls and only 48mm diameter of usable hole diameter. The Unifilter has straight internal walls, and a full array of holes to the side walls for even extraction throughout the puck.
Be aware of the fact that coffee extractions look different on the Unifilter than a standard portafilter, and this is good. Say goodbye to the "rat tail" and say hello to the "syrup rain". A stiffer bottom section means that the bottom surface doesn’t bulge out and converge all of the streams, giving you greater visibility into what’s actually happening in your puck.

Moreover, with a removable basket, espresso residue inevitably builds up in the crevices. Without frequent removal and cleaning or acid baths, this can become rancid. The Unifilter is a single piece with no hidden areas, so a simple water rinse after each use keeps it perpetually clean.
