Düsseldorf, September 22, 2025 – Water is the most essential beverage in our daily lives. However tastes differ here as well. In a survey conducted in seven countries, 72 percent of respondents claimed to drink tap water. Among those who avoid it, 45 percent say they do not like the taste¹. But what happens when the water is refined with a filtration and carbonation system?

In an external double-blind study, carbonated water from the GROHE Blue Home water system impressed consumers across all dimensions of taste. Refreshing, thirst-quenching, and revitalizing: enhanced tap water proves to be a convenient alternative to bottled water – without the heavy lifting, storing bottles, and the CO2 emissions linked to the production and transport of bottled water.

Blind taste test confirms good taste

In a double-blind study conducted by GROHE together with a renowned German testing and analysis institute, 60 participants sampled carbonated water from two tap-based water systems as well as from glass and PET bottles of eight brands. Neither the participants nor the test supervisors knew which water was being served in each glass (“double-blind”).

The result: across all ten taste categories, the water from the GROHE Blue Home system performed at a consistently high level.

Participants rated the water in every taste dimension on a ten-point scale – for example, for “refreshing” from “not refreshing at all” (1) to “absolutely refreshing” (10). The water from GROHE Blue Home scored particularly well in six dimensions: more than three-quarters of participants perceived it as refreshing (90%), thirst-quenching (88%), invigorating/vitalizing (87%), with a pleasant fizz (80%), not salty (80%), and neutral (77%). Almost as many described it as fine-pearly and light (73% each) as well as sparkling (70%), while more than half experienced it as soft (63%).

The GROHE Blue Home water system used the GROHE Blue Magnesium + Zinc filter, which purifies tap water in five stages, removing impurities as well as undesirable tastes and odors, reducing substances such as limescale and heavy metals, and adding magnesium and zinc.
