With the Unifilter® we created a portafilter revolution. Weber Workshops is extending that concept to the Unibasket®, utilizing the same construction and improvements on extraction that the Unifilter® brought, but in a “drop-in” basket form. Now available in 4 basket sizes, including an industry-first whopping 28g megafilter.

The Unibasket® is a portafilter basket created from a single, thick piece of stainless steel. Whereas typical baskets are made from thin wafers, the Unibasket® is forged from a 1.2mm thick blank of metal. The added thickness greatly improves the rigidity of the puck during extraction by reducing bottom face flex, a common cause of puck cracking and channeling during extraction. 

20g Unibasket® are in stock. The other sizes are available for PREORDER and will begin shipping in mid October 2023.



The Unibasket® 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 58.5mm puck from top to bottom. Technology invented by Weber Workshops, these are made with inimitable quality and craftsmanship. Accept no substitutes.

Now made for anywhere from 16g ~28g shots spread amongst 4 sizes (and all +/- ~1g with use or elimination of puck screen).

Included in package

  • 1 Unibasket®
  • 1 Retaining Spring (for use with standard 58mm portafilter body)
  • 1 Pack of EPFs (Espresso Paper Filters) - Unifilter size
  • 1 Stainless Steel puck screen


  • The height of the Unibasket® varies by size. If the existing basket in your spouted portafilter is shorter than that, the Unibasket® may interfere with the bottom of the group handle.
  • The Unibasket® will fit most bottomless group handles. It is NOT COMPATIBLE with bottomless group handles by ECM, Slayer, Gaggia, Rancillio and Breville.
  • This Unibasket® is optimized for use with our own BUCK which can be seen here.


20g Unibasket® are in stock. The other sizes are available for PREORDER and will begin shipping in MID OCTOBER 2023.

The Unibasket™ in action.

For about a hundred years, the basic construction of the portafilter has remained the same. We decided to change that.

Full Extraction Area

Due to how they are manufactured, typical 58mm baskets have angled side walls and only 48mm diameter of usable hole diameter. The Unibasket® has straight internal walls, and a full array of holes to the side walls for even extraction throughout the puck.
