Self-Rated Aversion to Taste Qualities and the PROP Taster Phenotype Associate with Alcoholic Beverage Intake and Preference

Sweet liking predicts liking and familiarity of some alcoholic beverages, but not alcohol intake: A population study using a split-sample approach

Sweetness has been proposed to be an important quality in the decision to consume alcohol, and strong preferences for sweet tastes have been associated with alcohol abuse. However, alcohol is characterized by a number of other sensory properties, including astringency and bitterness that may drive preference and consumption. Spinelli et al. (2021) classified individuals into three sweet-sensory liking clusters (High Sweet-Liking, Moderate Sweet-Liking, and Inverted-U) that differed in their sweetness optima and sensory-liking patterns (relationship between liking and sweetness, bitterness and astringency perception in a food model). The current paper replicates the sweet sensory-liking clusters in a new set of participants (n = 1976), and extends the predicted value of these clusters examining their relationship to wine and other types of alcoholic beverages by gender using a split-sample approach on a total of over 3000 adults. The sweet sensory-liking clusters had a predictive relationship for the familiarity and liking of some alcoholic beverages characterized by stronger tastes, but not weekly alcohol intake levels. Thus, although sweet sensory-liking clusters may be associated with the type of beverages and frequency with which a person will drink and enjoy a type of alcoholic beverage, they are poor predictors of the quantity of alcohol that a person ingests over the course of a week.

Influence of taste sensitivity on preference and sensory perception of mezcal

The perception of orosensory stimuli, which includes flavor, can vary between individuals. These individual variations in oral sensations can be due to genetic factors and it would appear that they can predict food liking and consumption. The most studied source of variation is related to bitter taste perception associated with 6-n-propylthiouracil (PROP) responsiveness. In this context, humans can be classified as non-tasters (NT), medium tasters (MT) and supertasters (ST). Evidence suggests that genetic variation in bitter taste perception contributes to differences in the level of irritation caused by alcohol perception in solutions. The aim of this investigation was to study the bitter taste sensitivity among a group of mezcal consumers and its relationship with sensory perception and preference through PROP taster status. The tests were carried out in the state of Oaxaca in Mexico. A total of 83 mezcal consumers were classified by their PROP taster status and were asked to provide sensory descriptors for five mezcal samples and rate them according to the level of liking. The three-solution test was used to classify the subjects as NT, MT, and ST, while a Multiple Factor Analysis (MFA) was used to visualize the sensory descriptors provided by these three groups. The proportion of MT subjects was 16%, while the proportion of NT and ST was 34 and 51%, respectively. The MT provided higher liking ratings for at least three mezcal samples. According to MFA, the mezcal samples were organized in a similar configuration along the two dimensions. However, NT mentioned a limited number of simple terms (strong flavor, tasteless, burning in the mouth) to describe the samples, whereas ST used a more complex vocabulary (astringent, smoky, scratchy aftertaste). These data suggest that the preference for mezcal samples was similar for non-taster and supertasters, but there are indications that the sensory perception of mezcal differs between groups.

Feature Papers in Sensory Analysis of Beverages

Sensory science is a young discipline that has proven to be very useful for the food and beverage industry, not only to guarantee the quality of the organoleptic properties of raw materials and processed foods/beverages, but also to increase the probability of the success of new developments, to understand consumer response and detect potential consumer niches, and to monitor competitors [...]

Optimization and Application of the Wine Neophobia Scale

Wine consumers’ willingness (wine neophilia) or reluctance (wine neophobia) to try new wines represent, respectively, an opportunity or barrier for product innovation and market development in the wine industry. Here, we first sought to validate and optimize the Wine Neophobia Scale (WNS) in a large sample of 1269 Canadian wine consumers. Both exploratory and confirmatory factor analyses showed that a seven-item scale was optimal. This modified WNS (mWNS) was then used to investigate demographic and behavioral correlates of wine neophobia. Using lower and upper quartile values, 316 neophiles and 326 neophobes were identified. Wine neophiles and neophobes did not differ with respect to gender or age; however, neophobes had lower household income, education, and wine involvement, and reported consuming fewer wine styles than neophiles. Interestingly, while neophiles drank wine considerably more frequently than neophobes—a finding that is mediated by wine involvement—total annual wine intake did not differ between the groups. Importantly, the price typically paid per bottle of wine also varied with wine neophobia. We recommend adoption of the modified mWNS as a useful tool for more fully understanding the drivers of wine behavior and providing guidance to wine marketers.
