MHW-3BOMBER Bottomless Portafilter 58 mm for La Marzocco (E61)
Without a spout you see the shot right at the bottom of the basket: where the espresso emerges first, whether the stream comes together in the centre or sprays to the side.
The portafilter from MHW-3BOMBER has a head made of food-grade SUS 304 stainless steel and a walnut wood handle. According to the manufacturer it fits La Marzocco and E61 group heads with 58 mm, but not 58 mm machines from Gaggia or Breville.
What you see in the stream is a hint, not a verdict. What counts is the taste in the cup and the brew ratio by weight, 1:2 as a starting point. Our opinion is one of many.

Tip from the roastery: Bottomless, you can see how evenly a coffee extracts. We recommend Cozy Chocolate and Nutty Delight, full-bodied with chocolate and nut. If you want maximum body without acidity, take Very Nutty. For the curious: Wild Peach, fruity and lively. That is our recommendation, one of many.
