Weber Workshops Unifilter – 49Mm Precision Portafilter Insert

Description

Say hello to the 49mm Unifilter®. You asked, we delivered. The revolutionary Unifilter- where the basket and the portafilter become one and the extractions are unprecedented-is now available for 49mm machines. If you own an Olympia Cremina (’67 – 2023) or a La Pavoni pre-Millennium (before Aug 2000), your coffee and your palate will thank you for this upgrade.

Built in exactly the same way as its big brother, we start with a solid mass of stainless that goes through a series of transformative manufacturing process to create a seamless, hardened, polished, and everlasting form to further enhance your espresso. Just like its 58mm counterpart, it is available with a solid stainless steel cored FKM rubber or Teak handle. Re-envisioned, reinvented, recreated, and fully revolutionary.

Basket Holes Active Area

Due to how they are manufactured, typical 49mm baskets have angled side walls and only ~37mm diameter of usable hole diameter. The Unifilter 49 has straight internal walls and a full array of holes to the side walls for even extraction throughout the puck. This is 75% more area (or elimination of the 43% loss), but the results are profound and delicious.

Cleanliness and Simplicity

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.

Extraction Dynamics

Bye bye “rat tail” and hello “syrup rain.” It’s physics making your coffee better.

A fresh view

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.

Materials

BODY: The Unifilter is made from a solid piece of Stainless 304 material. All of the holes are individually laser-ablated and go right up to the vertical wall edge, giving a true 49mm puck from top to bottom. Made for 16-18g shots (depending on the roast level and/or bean density).

HANDLES: All handles have a solid stainless steel core to give them heft and longevity. That is covered either by a thick FKM rubber sleeve, or a cored-out solid piece of solid teak wood.

The wood is dried below 5% moisture and pressure-infused with clear resin, this stabilised hardwood maintains its shape through moisture and temperature extremes, highlights the natural grain with a precision finish, and delivers long-term durability.
