11/21/2023 0 Comments Target expresso machineEven if your water looks clean, there will still be a small amount of particulate matter that passes through, and this can lead to clogged water passages and leaking seals.įiltration and softening prevent the most common threats to the reliability of your machine, but there are many other factors to consider. Additionally, water filters can reduce chlorine and other tastes and odors. This removes solids from the water, such as tiny pieces of dirt, rust, or grit. The other basic requirement is filtration. Also, because water quality in city water sources and wells changes seasonally, we recommend checking your water every three to four months. This will reduce heating efficiency, can clog water passages, lead to inaccurate readings from temperature and level probes, and cause failure of valves and seals which can cause a mess on your countertop. For most optimal results, the Specialty Coffee Association of America recommend hardness above 35ppm and below 85ppm.Ĭhecking your water hardness cannot be stressed enough because water that is too hard can cause excessive scale buildup inside your machine. Reverse osmosis systems typically will take all the mineral out of the water, and this is problematic as well as the machine requires mineral content for many of the internal sensors. As mentioned above, some mineral content (above 35 PPM) is necessary for the best-tasting espresso, and also for the machine to run without overfilling the boilers. We recommend using a water softener if you get a measurement above 85 parts per million (PPM) or 5 grains per gallon (GPG). These test strips will allow you to measure exactly how hard your water is. We recommend using a TDS meter or water hardness test strips (we include test strips with every machine purchase). Primarily, we are looking for clean, filtered water that has some but not too much mineral content. When it comes to brewing coffee, it’s important to understand that the more mineral content water has, the less it can take in from coffee, typically.”įiguring out the right water to use doesn’t need to be super complex. Water has all sorts of trace amounts of other minerals in it, giving both flavor and extracting ability. The ability for water to take things in is also predicated on the idea that it actually is a blank canvas, and that it has room to take those things in-only it isn’t. While brewing, water takes in-or extracts-solids & oils that coffee holds, giving that once clear water some real substance. It actually serves as the medium for flavor. “…When we talk about extraction in coffee, water is so much more than a clear, somewhat tasteless liquid. Just how important is the water you are using while brewing? Does it really matter? Our friends at La Marzocco describe it beautifully: This guide will explore how water interacts with coffee, expand on the right water to use for your machine, and offer a few options to ensure you are getting the best out of your machine. Also, the quality of your water can either distract or enhance the taste of your espresso, so it’s important to get your water dialed in for longevity and great taste. We want to fill you in on how you can avoid ever having to deal with a leak, a failed heating element, or a clogged machine, and be confident it is being well cared for and will continue to serve your coffee needs for years down the road. Many of the machines we receive in the tech department have had repeated issues that are caused by poor water quality, which is something that seems to be overlooked too often.
