MHW-3BOMBER58.5mm Espresso Puck Screen Metal Espresso Filter Reusable Coffee Filters for 58mm Portafilter Basket 0.8mm Thickness Titanium Coating Gold FG5587

Good

Fits a 58mm portafilter well. After pulling a shot of espresso, you can see where each hole was evenly distributing water over the top area of the puck surface. I can't say it has changed the flavour profile of my espresso in comparison to a basic puck screen. But it looks classy and works as advertised!

Not a coffee game changer, but here are the benefits:1) Cleaner operation of group head over multiple shots2) An extra layer of dispersion to avoid channeling incrementallyNegatives:1) Knocking out requires two steps - knock gently to remove disc, knock hard to remove puck - if you don’t like touching not for you2) On finicky beans that require a very even distribution and acceptance of water from the group head will actually reduce flow and cause over extraction. So you have to know which beans and grind benefit and don’t from using the disc OR you need to recalibrate grind and pressure for using disc with that finicky bean extractionOverall Better than other screens/discs I have used due to thinness and difference in the two sides. Knowing when and how to use optimizes. Not as big a deal if you dial in on one bean and grind.

I’m unable to download the video, but using my Ceado grinder and Rocket Milano Espresso machine and this screen for the first time in 8 years made a great coffee pull go to sublime! Must admit I used Temple Coffee’s Java Argopuro Mountain Espresso. The crema formation was spectacular!!!

… and probably any other 58.5mm portafilter. The thickness of 0.8mm makes the difference! My old (noncore window screen) filter was 1.7m and I couldn’t use 18g of coffee below it while still being able to attach the portafilter without it leaking; so I was forced to use 17g. Now, with the MHW-Bomber SUS304 filter, the portafilter attaches nicely and without too much force. No leaks. I swear, my first double shot straight up espresso tasted sweeter!! Highly recommend this filter! Rinse and wipe dry after each use.
