MHW-3BOMBER DEX Precision Basket 58 mm 20 g – Deep Extraction
Turning the empty basket in the light, you see the holes sitting in clear rows – arranged rectangularly, finely drilled. As the shot pulls, the water then runs calm and even through the whole bed.
Nobody needs a new basket. Wanting one, or not, is entirely a matter of curiosity, and we respect that decision either way. If you're here, you know why.
What makes this basket special
The DEX – Deep Extraction – relies on 872 precise holes arranged in a rectangular pattern. The holes are stepped-drilled: this distributes the water evenly across the whole surface and supports a consistent, deep extraction. Made from AISI 304 stainless steel with straight walls and a flat bottom, which helps with even tamping and gives the puck support.
We like to work with a 1:2 ratio, so around 20 g of grounds to 40 g of espresso, and let the weight decide, not the stopwatch. Taste and smell are inseparable here: much of what we experience as aroma happens retronasally, as the espresso passes over the tongue and into the throat. 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 a medium to larger shot and likes to work with their extraction. If in doubt, check whether the 26 mm basket height fits your portafilter. Every budget is welcome, and 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. Even distribution beforehand comes from a distribution tool and tamper – affordable and precise from Normcore, with more material ambition from Weber Workshops.

Roastery tip
A good basket helps, but the bean makes the flavor. For 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, Wild Peach goes into the grinder. That's our recommendation, one of many.
