Can Tap Water Really Beat Bottled Sparkling Water? The Surprising Results Are In

For years, the choice has been between the convenience of the tap and the perceived quality of bottled water. Many people avoid tap water simply because they dislike the taste. But what if your kitchen tap could deliver water that not only rivals but surpasses bottled brands in taste?

In a groundbreaking double-blind study, the GROHE Blue Home water system did just that, scoring high across all taste dimensions—proving to be refreshing, thirst-quenching, and pleasantly fizzy.

The Ultimate Taste Test

To settle the debate, GROHE partnered with a German testing institute to conduct a rigorous double-blind study. In the test, 60 participants sampled carbonated water from the GROHE Blue Home system, another tap-based system, and eight different brands of bottled water in both glass and PET bottles. The “double-blind” method ensured complete impartiality, as neither the participants nor the testers knew which water they were evaluating.

The Verdict: A Resounding Success for GROHE Blue

The results were precise: water from the GROHE Blue Home system consistently achieved high scores across all ten taste categories.

 The Secret Behind the Superior Taste

The exceptional taste is no accident. The GROHE Blue Home system utilises a five-step advanced filtration process. This filter removes impurities, undesirable flavours, and odours while reducing substances like lime and heavy metals. Crucially, it also enriches the water by adding essential minerals, such as magnesium and zinc. Just two litres of water from the GROHE Blue Home can contain as much magnesium as four apples.

More Than Just Great Taste

Beyond its award-winning flavour, the GROHE Blue Home offers a range of benefits that make it a brilliant addition to any modern kitchen.

Unmatched Convenience:

Say goodbye to the back-breaking task of lugging heavy crates of water bottles. The GROHE Blue Home system delivers up to three litres of perfectly chilled, filtered water per hour, straight from your tap. You can choose between still, medium, or sparkling water to suit your preference, all without the inconvenience of heavy lifting.

A Sustainable Choice:

Make a significant and positive impact on the environment with every glass. Compared to PET-bottled water, the GROHE Blue Home system reduces CO₂ emissions by 76% and saves up to 7 litres of water for every litre you drink, due to the intensive production process of bottled water. By choosing the GROHE Blue Home system, you’re not only enjoying great-tasting water, but you’re also making a responsible and sustainable choice.

Perfectly Personalised:

The innovative cooling system of the GROHE Blue Home system allows you to adjust the water temperature to your liking, ranging from 5 to 10 °C. This feature ensures that every glass of water you pour is ideally suited to your taste, making you feel catered to and special.
