Normcore51mm Puck Screen - Lower Shower Screen - Metal Coffee Reusable Filter for Espresso Portafilter Filter Basket 51mm - 1.7mm Thickness 150μm - Stainless Steel

This is a fantastic product to preserve the life of your expresso machine. It's weighty and dense. The matte black finish looks really nice, and it fits nicely in my 54 mm portafilter.It can also be easily cleaned just by being rinsed off. I would advise soaking it in a coffee cleaning product like cafiza once a month to remove any build up. If you're ever unable to salvage this product, they're so cheap it's easy just to pick up another one.Not only does it help with water distribution through the puck, it prevents your shower head from sucking grinds into it. If your machine doesn't have a solenoid, I still recommend this as it prevents the coffee from touching your shower head.All in all, this is a nice preventative measure to prolong the life of your machine and reduce the amount of cleanings it requires.

Just received the Normcore 58.5mm Puck Screen, and it's a beauty. Crafted from 316 stainless steel with a titanium PVD coating, its arrival in professional, no-fuss packaging impressed us from the start. The packaging itself is minimalistic and quality in its presentation alone.Unwrapping revealed the puck screen's sleek design, featuring a subtle Normcore label that's both stylish and understated. It fits our portafilter like a glove, adding not just to the aesthetics but significantly improving our coffee brewing process. It's been instrumental in reducing channeling and keeping things clean, making every brew smoother and more consistent.After a few uses, we're thrilled with its performance. It's not just a tool; it's an upgrade to our coffee setup, making each cup that much better and easier clean up as well. This puck screen is definitely a standout addition to our coffee-making process! Thank You!

I bought this puck screen primarily to see why everyone on YT was using them and in the interest of keeping my grouphead screen clean. The screen on an Isomac Millennium is a major chore to remove (no screws) and takes a ton of backflushing to clean on a regular basis.The first thing I learned was that this puck screen would not fit the OEM basket which has an ID of less than 58.5mm and is tapered on top of that. I decided that after 20+ years of using that basket I could also experiment with a new 58.5mm straight-walled basket, so I ordered one and the screen fits perfectly. It is also doing yeoman's work in terms of keeping the grouphead screen clean.My espresso has had a slight increase in sweetness, though I've now modified the basket and added a screen, as well as just completed a thorough cleaning/descaling, so who's to say what the impact of the screen was on flavor. However, in terms of tidiness, it has helped immensely. It's very easy to remove and clean. Wish I had started using one sooner.

My first thought was ‘oh great, another gimmick for espresso nerds.’ But having used this little ‘puck screen’ for a few months now, I’m convinced it’s a useful tool… not indispensable, but definitely a nice addition to my shot-making process.The huge plus: it separates your puck from the shower screen on your E-61 grouphead. As a result, you won’t need to pull the gasket and screen every day or two to remove coffee residue from the screen and to clear the groove around the inside edge of the head. It will stay clean as a whistle. This also reduces the need to backflush your machine with a cleaner like cafiza, which chips away at the lubricants on the valves and cam inside the group. That means less grouphead maintenance as well.As for improved extraction and less channeling, I can’t vouch for that one way or the other in a scientific way. However, I do find it is a bit easier to dial in my tamp, grind and dose; I seem to pull more consistent shots; and the spent pucks are more uniform and uniformly saturated when I dump them.My two issues/concerns about using this are readily addressed.First, I dropped my typical 19 gram dose to 18 grams to avoid ‘overstuffing’ my portafilter and making it difficult to cinch down to 6 o’clock on my ECM machine.Second, I worried that this would draw heat from the brewing water and the basket, resulting in an underextracted shot. The simple solution is two-fold: A) I fill my 5 ounce cup with boiling water and drop the puck screen in while I’m grinding beans and packing the portafilter basket. Then I dump the cup, put the hot screen atop my tamped coffee (careful of those fingers!) and proceed. B) I do a longer preinfusion to ensure the coffee is amply saturated before I begin extraction at 9.5 bar. I shoot for a 1:2 coffee to espresso ratio and extraction around 30 - 32 seconds with most medium roast beans.All in all, this has been a real value proposition for the $20 investment. Recommended, if you’re willing to expend a little extra effort making your espresso.

I bought this to keep my espresso maker's group head clean and to help reduce the soggy pucks I was getting on my Breville Bambino Plus. Since I've been using it, the group head is definitely clean and I no longer have to run a shot's worth of water through to clean it after my shots.As for the soggy pucks, it does help. Not as much as I'd like but it's definitely allowing the Bambino Plus to remove more water from the top of the portafilter at the end of the shot when the solenoid valve actuates. Still not as much as I'd like. But it's better than without the screen.Flavor of my shots has not been affected nor has channeling. I'm pretty good at puck prep so I don't get channeling much at all anymore so I don't think this screen is effective there. Flavor of my shots is still what I'd expect from the beans I use so the screen has not affected that at all.Otherwise it's a decent addition to my workflow and it's definitely helped keep the machine clean and the pucks less soupy.

Sturdy and good quality, does what we bought it for.

Con estas pantallas e conseguido una extracción más pareja

Muy buenos materiales, se siente rígido tanto la base para ponerlos como la rejilla, en realidad no se nota mucho la mejora en la extracción pero en mi caso la limpieza de la ducha y la salida del bagazo del portafiltro es lo que más me agrada, no dudo que no mejore la extracción pero me convenció más por la limpieza, el único pero seria la limpieza del mismo pero nada complicado, con la misma lanceta o agua caliente se limpia fácil.

Llevo dos meses usándolo, no solo es mucho mejor cubrir los ligeros errores de tamping sino la extracción es más pareja y la pastilla más estable. Un truco es dejarlo remojando en agua caliente unos minutos y luego enjuagar suficiente todos los días y una vez cada quince días remojarlo en vinagre blanco y enjuagar Perfecto para qje no agregue sabores indeseables al café
