MHW-3BOMBER58.5mm Espresso Puck Screen with Round Hole Metal Espresso Filter 0.8mm Thickness Coffee Filter for La Marzocco/Gaggia FG5586

Ich verwende dieses Puck-Sieb in einer La Marzocco Micra. Diese hat in der Mitte des Siebes eine Schraube, die durch das Puck-Sieb schön rundherum abgedeckt wird. Die Verarbeitung des Siebes ist toll. Ich verwende das Puck-Sieb ausschließlich damit die Maschine durch das Kaffeepulver aus dem Siebträger nicht verschmutzt wird. Und genau hier sind Papierfilter besser. Man kann sie perfekt mit dem benutzten Puck entsorgen, während man das Metallsieb reinigen muss. Das Sieb der Maschine bleibt mit Papierfiltern zu 100% sauber während das vorhandene Metallsieb durch die mittige Auskerbung für die Schraube, doch ein wenig Pulver reinlässt. Außerdem ist das Metallsieb etwas dicker als ein Papierfilter, ergo passt weniger Pulver in den Portafilter. Das ist nicht tragisch aber man muss es wissen. Für die Öko-Freunde: Ich weiss nicht ob das Wasser zum Reinigen des Metallsiebes wirklich umweltfreundlicher ist als die dünnen Papierfilter. Sei‘s drum: wer einen Siebträger mit Schraube in der Mitte hat und ein Metallsieb will, kann getrost zugreifen, es lohnt sich. Persönlich bevorzuge ich die Papierfilter, werde das Teil aber trotzdem behalten.

I bought it mainly to keep my shower head clean, which it does wonderfully, but it also helps to ensure even water distribution throughout the whole puck and it's thin enough where I didn't have to cut down my dose, plus it completely eliminated wet pucks, when the dose wasn't just right. Definitely a 10/10 product.

I have definitely come to the conclusion that there is an advantage in using a puck screen when making espresso. I learned this using a puck screen on my old 51mm portafilter equipped espresso machine. What I objectively noticed was the shower screen was much cleaner, there was a reduction in puck channeling, and there also seemed to be a bit more crema. So it follows that a properly fitting puck screen would also improve the taste of the espresso. Also, the coffee puck seemed to pop out of the basket more easily, and in a more intact condition at the end of the extraction.I got this MHW-3BOMBER 58.5mm puck screen (with round hole) to use with my new Gaggia Classic Evo Pro, as it’s shower screen screw protrudes a bit. Unfortunately, when I first used it with the supplied standard 58.5mm portafilter & double shot basket, and loaded my usual 18 grams of coffee, the portafilter didn’t seem to want to fit on the coffee brew unit. Of course, if I cut down on the coffee amount, it did fit. I am not faulting the MHW-3BOMBER puck. I believe the supplied portafilter & double shot basket of the Gaggia Classic Evo Pro, has very little excess headroom to accommodate a coffee puck screen, even a thinner one (0.8 mm) like the MHW-3BOMBER (for my dark espresso dose, anyway).......Update 02-02-2024: Per a knowledgeable friends recommendation; I swapped from an espresso dark-roast to a medium dark roast coffee, and dialed the grind finer by one notch. Now the supplied standard 58.5mm portafilter & double shot basket, and MHW-3BOMBER puck fit the brew head of my Gaggia Classic Evo Pro just fine, even at my desired coffee dose (apparently darker roasts are typically less dense than lighter roasts, and take up more room by weight).I have also acquired a good aftermarket portafilter (bottomless) and an IMS double shot basket that has extra room. These also, in addition to using the MHW-3BOMBER puck, fit the brew head of my Gaggia Classic Evo Pro perfectly......Because the overall build quality, and specifications of the MHW-3BOMBER puck screen impressed me, I bought a second one as a gift for the biggest coffee enthusiast I know, who owns a La Marzocco (which also uses a 58.5mm portafilter, and it’s shower screen screw also protrudes a bit). He had once tried another brand of puck screen (thicker, and without the round hole) and it had not fit his La Marzocco properly, even though he was using an aftermarket portafilter and basket, that had more headroom. He fit the MHW-3BOMBER puck screen I had gifted him to the aftermarket bottomless portafilter he usually uses, loaded his usual dose for two shots (18 grams), and it fit and worked perfectly. He also was very happy with the results, and plans to continue using it in the future.

Works great and helps keep the shower screen clean

The hole is big enough to let you still use a puck screen with a shower screen that has an extruding screw. I like the design as well!
