Product Information

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. A faster flow rate means you can grind finer. Grinding finer will increase your extraction. Higher extraction theoretically leads to more flavor in your shot. I say “theoretically” because more extraction can mean more bitter compounds, but generally, people prefer higher extraction. With a relatively low price point compared to so many things in the jungle that is espresso accessories, it’s a small investment that can make a big difference in your workflow and shot consistency.

Some people think they are less efficient at dispersing the water stream than the mesh filters and more prone to channeling. 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. 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. Distributors are equally important and will help you spread the coffee grounds more evenly and enjoy better coffee. 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. WDTThe ability to increase extraction with a paper filter is an interesting find and worth exploring for home baristas. 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.

Make sure you follow the guidelines for brewing espresso with your coffee machine to avoid damaging the coffee grounds basket in mint condition. Portafilters A good way to detect any issues with your coffee extraction and whether it’s channelling or not is to use a naked portafilter. WDT, or Weiss Distribution Technique, is a method of evenly distributing the coffee grounds in the portafilter basket. This technique involves using a fine needle to stir the coffee grounds, ensuring that they are evenly distributed and free of clumps. For paper filters, the answer is a stronger yes – they do improve espresso. However, it’s a nuanced answer with a few different effects to explain.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. We see this time and time again the coffee industry ‘steals’ ideas and concepts from the wine industry. So, similar to wine-tasting glasses, there are tasting cups for coffee, ideal to taste coffee and identify unique features of different coffee beans. The espresso filter distributes the water more evenly across the bottom of the filter basket, which allows the espresso to flow through every basket hole for a faster flow rate. There is a secondary effect that home baristas have observed when using stainless steel screens. The final coffee cup will have more body. Now this is interesting for a brewing method that is known for its body. A steam wand spray removes finer particles from the filter’s surface. You can just steam it in a milk pitcher with your espresso machine.

Replace the screen: If the screen becomes damaged or heavily corroded, it's important to replace it to ensure the quality of your espresso. Mesh filters are the original choice. They are easy to buy online and can be found in various sizes and densities. 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.   If you read our guide on how to make espresso, we mention a few espresso accessories there, but we deem the accessories optional. However, this article is an advanced technique, for the home barista who want to pull the perfect espresso shot. A Bit of HistoryNo 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.

Stainless steel filters are on the surface very similar to Aeropress steek filters. However, they have a smaller diameter and are designed to fit your basket. They offer a couple of advantages over mesh filters: Using a WDT tool can help to improve the quality of your espresso shot by ensuring an even extraction. This technique is particularly useful when working with freshly roasted coffee, which tends to be more prone to clumping. Pre-InfusionAdding a paper filter underneath the coffee grounds is an easy way to make brighter, sweeter shots. That brighter flavor may work against you if you prefer richer, more full-bodied shots or like making milk-heavy drinks like lattes. Best of all, paper filters can be thrown away with your ground coffee, so they don’t add any maintenance. 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. 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. Coffee grounds Baskets 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.
