Product Information

I know that it is a bit anticlimactic to talk about the need of the shot screen after we talked so long on how it can improve our espresso. But I wanted you to have a good idea on what it does, before concluding if we really need them. Make sure you follow the guidelines for brewing espresso with your coffee machine to avoid damaging the coffee grounds basket in mint condition. Portafilters The pre-infusion will mostly solve this problem by dumping a small amount of water at a low pressure on the coffee bed, before the extraction. However, the water will still pour in streams from the shower head, and there are still a lot of chances to get channeling.

You can use paper instead of a screen. Use scissors to cut baking paper in the shape of the coffee basket and once you’re done with tamping you can put it above the coffee grounds. It’s a relatively recent innovation in specialty coffee. I think the tiny brand Bplus from Taiwan may have been the first one to introduce the concept, although I may be wrong. One approach is to use a calibrated tamper, which allows you to apply a consistent amount of pressure. Another technique is to use a distribution tool, which helps to evenly distribute the coffee grounds before tamping. WDT The third change with a paper filter is cleanliness. I have less spraying on my bottomless portafilter using a paper filter. I love bottomless filters to see the flow and easier cleaning, but the spraying is constant issues. Many consumer espresso machines, like Breville, are set to high pressure, which inevitably causes spraying. The more even flow of a paper filter greatly reduces this spraying.Soak your filter in a coffee-specific cleaner like Cafiza for a deep clean, once in a while to remove nasty oils. Some people think they are less efficient at dispersing the water stream than the mesh filters and more prone to channeling. Thanks for the question - it's made from 316 stainless steel, so unless you accidentally throw it away or abuse or break it I'd be surprised if it doesn't last for many thousands of shots.  We've been using the same screen daily for the last few months - probably a few hundred shots at least - and it's identical to a brand new one, so in theory these things will last indefinitely.  

Theoretically, I can see how it should disperse the water more evenly. However, it’s difficult to predict how the water actually flows inside the basket when it’s under pressure. No matter how well you did your tampering, if the coffee basket is damaged (which happens due to excessive usage or when not following the best practices the manufacturers recommend). As a result, the water finds the easiest way to run through the coffee grounds and (as you might have guessed it) this leads to espresso channelling. First, the effect of straining out the oils, lipids, and heavier fines. This improves clarity and makes for a perceived sweeter shot, as discussed earlier.It’s useful to have them both IMO, but this doesn’t necessarily mean you need to break the bank and buy the most expensive ones. Go ahead and read about how to clean an espresso filter basket easily.
