The world's first unibody portafilter, a revolution in espresso preparation.
For about a hundred years, the basic construction of the portafilter has remained the same. We decided to change that.
We recreated the portafilter out of a single piece of stainless steel. No more removable basket and crevices for espresso gunk to build up over time. No more citric acid or vinegar baths to remove grime. Use it, rinse it, wipe it, and it stays endlessly clean. Since you aren't subjecting your basket to repeated acid baths, it will last virtually forever.
And it goes deeper than that. The espresso basket, until now, has been a deep-drawn piece of stainless steel with punched holes in the bottom. This was an inexpensive and efficient way to make something that works. However, this manufacturing process limits both the shapes of the side walls (they need draft, which results in slanted walls), and the proximity of the holes to those walls, which is not optimal for even extraction throughout the puck.With the Unifilter’s unibody construction, the inner walls are perfectly vertical, and the holes aren’t “punched” all at once. They are laser ablated, one by one, with an even pattern right up to the vertical walls. And since the it is one big mass of stainless steel, the heat retention is also significantly improved. There is no difference in temperature between your portafilter body and your basket, as they are now the same piece.
For our handles, we use a stainless steel core throughout the entire length to give the portafilter heft and strength. We made two versions of handle: one in a black FKM rubber (like formula 1 engine gaskets), and one in solid teak finished in German non-VOC oil.
Used in conjunction with Weber’s EPFs (Espresso Paper Filter) and the included mesh flow disruptor, you can unlock more from your espresso shot than has ever been possible. Improving your extraction means less wasted shots, and that in turn means less wasted coffee. Heirloom construction and the elimination of the need for acid baths is both more hygienic and more environmentally friendly in the long run.
