Most baristas are aware that since the majority of an espresso is made up of water, the quality of the water used is an important factor to the flavor of the espresso.
However, something that is perhaps less obvious, particularly to home baristas who are deciding whether or not purchasing a water filter is worth the investment, is that quality water is also vital to the longevity and health of your espresso machine.
Why is this?
Sediment in water can lead to blockages and water flow restriction, which can lead to a chain reaction that could cause heating circuit or hydraulic circuit malfunctions. This is more common than you might think.
Additionally, limescale buildup in your boiler will eventually lead to a restriction of steam pressure that directly affects the quality of your milk.
Due to the rising costs of labour and shipping part replacements, it’s certainly worthwhile to invest in a water filter for your espresso machine, even if you’re a home barista.
