Why Water Quality Is a Bigger Deal Than You Think
Black coffee is over 98% water — and even in milk-based drinks, water’s still the main ingredient.
So if the water’s not right, your coffee won’t be either.
Unfiltered water can dull flavour, damage your machine, and even void your warranty. Whether you run a café, hotel, or restaurant, water quality is never something to overlook.
What unfiltered water can do
- Dull or bitter-tasting coffee, no matter the beans
- Limescale buildup in your machine’s boiler and pipes
- Costly breakdowns and engineer callouts
- Reduces lifespan of your machine
- Warranty risks due to scale damage
- Inconsistent flavour from cup to cup
What Happens When You Skip Water Filtration
Skipping water filtration might seem like a small thing — until it leads to expensive repairs, poor coffee, and frustrated customers.
Here’s what can go wrong:
Limescale buildup
Clogs up boilers, pipes, and valves — reducing efficiency and causing long-term damage.
Machine Downtime
Unfiltered water leads to breakdowns, meaning lost sales and unexpected callout costs.
Inconsistent Taste
Your beans haven’t changed — but your water has. That’s why every cup tastes slightly different.
Short Machine Lifespan
Without protection, your machine components wear out faster — costing you more long term.
