When we talk about coffee quality, we tend to focus on the beans and the machine. But one of the biggest and most overlooked factors is water. It makes up more than 90 percent of every cup of coffee.
How does water affect flavor?
Minerals in water extract aroma and flavor from ground coffee. Water with too few minerals produces coffee that tastes thin and flat. Too many minerals can make it taste dull with a lingering bitterness, masking the aroma you’d expect from quality beans.
That’s why two cafés can use the same beans, the same machine model and the same settings, yet get different-tasting coffee.
Limescale is the machine’s silent enemy
When hard water is heated repeatedly, minerals settle and build up in the heating system and water lines. This can lead to:
- Longer heating times and higher electricity use
- Fluctuating temperatures, making each cup inconsistent
- Reduced water pressure as the lines become narrower
- Long-term boiler damage, one of the most expensive repairs
Limescale is dangerous because it builds up out of sight. By the time you notice it, it’s often too late to prevent the damage.
Water filters, a small investment that pays off
The right water filtration system helps keep water hardness at a level suited to coffee extraction and can significantly extend your machine’s lifespan. Compared with the cost of boiler repairs or lost business while the machine is out of service, it’s one of the best investments you can make in your coffee system.
It’s important to replace filters based on actual usage, not wait until the flavor changes. A café selling hundreds of cups a day will need more frequent filter changes than an office serving just a few dozen.
How to get started
- Test the water at your site before choosing a filtration system, as water quality varies greatly by location.
- Choose a filtration system suited to your usage, rather than choosing based on price alone.
- Keep a clear record of filter replacement dates and assign someone to be responsible.
- Check for limescale buildup regularly, alongside deep cleaning the machine.
