Carbonated water (AKA soda water, sparkling water and mineral water) is a billion-dollar industry that caters to every budget: from ultra-cheap home brands to luxury imports sourced from Italy and Norway. Sodastream recently conducted a blind taste test to determine whether anyone can actually tell the difference. Here are the results.
To determine the quality of five sparkling water brands, SodaStream conducted a blind taste test with 100 Australian participants. The brands included in the test were Mount Franklin, Voss, Santa Vittoria, San Pellegrino, Woolworths' home brand and Soda Stream tap water.
They discovered that hardly anyone could tell the difference between the expensive imports and cheap local versions. In fact, most people slightly preferred the latter.
Now, it goes without saying that these findings should be taken with a grain of salt: SodaStream does have a vested interest in the results, after all. Nevertheless, it's interesting to see how the non-SodaStream brands ranked in relation to one another.
Of the pre-carbonated options, the two cheapest brands came first and second. Voss, which costs over $6 per litre, scored a less than impressive 5.8 out of 10.
This seems to suggest that any ol' brand will do when it comes to sparkling water. If the results are genuine, the price/quality relationship is mostly psychosomatic. You can check out how each brand ranked and how much they cost per litre in the infographic below.
