MHW-3BOMBER BEP Precision Basket 58 mm 18 g – dual-layer filter basket
Freshly ground coffee falls into the basket, you level it and tamp – and as the shot pulls, the espresso runs calm and clear. Hold the basket up to the light and you see hundreds of fine, laser-drilled holes, each one identical to the next.
Nobody needs a new basket. You want it – or you don't. That's a decision made out of curiosity, and we respect it either way. Whoever is here knows why.
What makes this basket special
The BEP – Butterfly Effect Power – works with dual-layer filtration: two overlapping layers of holes catch fine particles before they reach the cup. The result is a clearer cup with less fines. The 745 laser-drilled holes, each 0.16 mm, distribute the water evenly across the whole puck.
The base is reinforced to 0.8 mm and barely flexes under pressure – that flexing is a common cause of channeling in the coffee bed. Straight walls and a flat base help with even tamping. We like to work with a 1:2 ratio, so around 18 g of grounds to 36 g of espresso, and let the weight decide, not the stopwatch. It's our observation that the choice of basket fundamentally changes the aroma profile – that's our view, one of many.

Who it's for
For anyone with a 58 mm portafilter who pulls the classic double espresso and likes a clear cup with few fines. Every budget is welcome. You belong here because you love coffee – not because you run a particular basket.
What goes with it
The basket fits standard 58 mm portafilters from our Portafilter Collection. For even distribution beforehand, WDT tools and tampers do the job – affordable and precise from Normcore, with more material presence from Weber Workshops.
You'll find the matching machine in our Espresso Machines Collection, the grinder in our Coffee Grinders Collection. Still deciding? Use our advice tool.
Frequently asked questions
What does dual-layer filtration mean?
Two overlapping layers of holes catch fine coffee particles before they reach the cup. This results in a clearer cup with fewer fines.
What dose is the basket designed for?
For 18 g – the most common amount for a double espresso.
Which portafilters does it fit?
Standard 58 mm portafilters, including bottomless ones.
What does the reinforced base do?
The 0.8 mm material thickness keeps the base in shape under pressure and prevents deformation and channeling in the puck.
Roastery tip
A clean basket helps, but it's the bean that makes the taste. For a dense, sweet espresso, we like to reach for Cozy Chocolate and Nutty Delight. If you like it full and round without any acidity, stick with Very Nutty; for a fruity experience, reach for Wild Peach in the grinder. That's our recommendation, one of many.
