Consumer perception and preference of bottled and tap water

Résumé

In order to understand consumer behavior toward drinking water, it is first necessary to determine sensory perception and liking for tap and bottled water. Nevertheless, sensory analysis of water is a challenge as drinking water is supposed to have almost no taste. Therefore, a methodology based on a perceptive sorting task was designed for that purpose. Six bottled mineral water and six types of tap water were presented to 389 consumers who had to group these samples according to their sensory similarities, describe their groups and give their preferences. The resulting sensory map was found to be mainly driven by the overall level of mineralization. Tap water, after being passively dechlorinated, did not perform differently from bottled water in all aspects for most consumers. Basically, three main tastes of water were highlighted and linked to the amount of minerals. The study demonstrated that the most likely preferred types of water are those with medium mineralization (total dissolved solids 3002013350 mg/L), which are perceived as tasteless and cooler. Practical use of the research presented in the present article is in water industry. This study enabled to understand the basis of consumers' perception and preference among drinking water and is a starting point in understanding consumers' behavior toward drinking water. There is also a methodological interest in the use of sorting tasks associated with preference ratings, which demonstrated its efficiency in assessing the links between perception and preference in water.
