This study concerns the expectations, liking and emotions related to the consumption of conventional beer and non-alcoholic beer (NAB), which are related but different products. These beverages are derived from the same raw materials and have undistinguished visual sensory cues. However consumers acknowledge the differences between them in terms of flavour, functional and emotional conceptualisations. Of particular interest here is how prior experience with beer and NAB and the conceptual information this generates in a consumer, can influence his or her response to its consumption in an appropriate setting - a bar. The labelling of a sample as beer or non-alcoholic beer was employed as a prompt to study the effects on liking and emotions provoked, when drinking a beer or a NAB, in a bar. Over 4 sessions, 155 consumers drank a glass of beer or NAB under two different conditions, labelled either correctly or incorrectly with respect to the actual composition of the sample. Questionnaires were used to rate the liking and emotions prior to and after consumption. The naming of NAB as beer significantly increased the liking and changed one emotion towards a positive direction, namely participants felt more fulfilled. When beer was presented as NAB it did not affect the liking but did significantly reduce the intensity of six positive emotions. Participants felt less comforted, exuberant, good, happy, joyful and loving. This study showed that labelling and the conceptual information generated in consumers might influence their response after consumption of these beverages.

Individual sensory properties of food and beverages are not perceived independently during consumption and their interaction will determine what consumers perceive and prefer. Many dynamic processes are involved in flavour release during the consumption experience and therefore its perception should be measured dynamically. To investigate how dynamic sensory and emotion profiles interact and how this relates to temporal liking, this study used a multi-sip approach with temporal dominance of sensations (TDS), temporal dominance of emotions (TDE) and temporal liking (TL), to compare three beers with small sensory differences in hop aroma: control beer (0% hop aroma), low_c beer (0.08% hop aroma) and high_c beer (0.16% hop aroma). Seventy-one beer consumers consumed a glass of each beer while performing TDE + TL and TDS + TL, on consecutive days in a sensory lab. Adding different concentrations of hop aroma in beer resulted in different dynamic sensory profiles without a difference in liking. The attribute floral was dominant in the high_c beer and in the last stage of consumption. TDE revealed an improvement of the emotional profile of the high_c beer at the beginning of consumption: three positive emotions, relaxed, pleased and happy were dominant, whereas for the other beers, one positive and one negative emotion were dominant, relaxed or pleased and disappointed. Overall differences between beers based on total duration of dominance were clear when looking at sensations rather than emotions while the combination of dynamic profiles of sensations and emotions showed a slight discrimination between the beers. It can be concluded that the subtle changes in the aroma resulted in differences in temporal dominance of sensations, did not affect liking and only slightly changed the emotion profile. The method used in this study remains to be proven further for use in food-related research and new product development, especially in the case of subtle changes.
Temporal dominance of sensations, emotions, and temporal liking measured in a bar for two similar wines using a multi-sip approach

Eating and drinking are dynamic processes where both sensations and emotions might evolve or change over time during multiple bites/sips. However, most previous studies have measured food‐evoked emotions statically, that is, at a fixed time point after consumption and using a single bite/sip approach. This study aimed to explore the sensitivity of temporal dominance of sensations (TDS), of emotions (TDE), and temporal liking (TL), using a multi‐sip approach, to differentiate between two comparable tasting wines. A glass of wine, in an appropriate consumption context, a bar, was served to 69 consumers, in two different sessions. It was shown that TDS and TDE captured small differences between equally liked wines. Wines were distinguishable during consumption, based on the dominance of basic sensations such as acid, bitter, and dry, rather than aromatic sensations and based on three emotions pleased, comforted, and relaxed. These emotions were dominant in both wines and in all stages of consumption but differed in the dominance rates. So, the impact of wine consumption on emotions was more uniform during consumption while new sensations became dominant during drinking.
