Why Filtered Water Makes Better Tea and Coffee

When it comes to enjoying the perfect cup of tea or coffee, we often focus on the quality of the leaves or beans. However, one of the most overlooked ingredients is also the most essential: water. Since a typical cup of tea or coffee is made up of around 98% water, the quality of the water you use can dramatically affect both the flavour and aroma of your favourite brew.

The Hidden Impact of Tap Water

Tap water in the UK often contains a range of impurities—including chlorine, heavy metals, limescale, and sediment—that can negatively affect both taste and health. While it may meet basic safety standards, it’s far from ideal for making high-quality tea or coffee.

Hard water, which is common in many areas of the UK, contains a high level of calcium and magnesium. This can lead to scale build-up in your kettle or coffee machine, reduce appliance lifespan, and leave a chalky film on the surface of your drinks.

How Filtered Water Enhances Flavour

Filtered water removes these unwanted elements, providing a cleaner, purer base for brewing. The absence of chlorine and heavy metals allows the natural oils in coffee and the tannins in tea to shine through, producing a smoother, more aromatic cup.

In blind taste tests, both tea and coffee made with filtered water consistently outperform those made with unfiltered tap water. The difference is often described as richer, more balanced, and less bitter.

Better for You, Better for Your Appliances

Using filtered water not only improves the taste but also benefits your health and household appliances. It reduces your intake of potentially harmful substances and helps prevent scale build-up in kettles, espresso machines, and coffee brewers—saving you money on maintenance and replacements in the long term.
