Wine involvement interaction with dining group dynamics, group composition and consumption behavioural aspects in USA restaurants

Purpose The importance of the wine involvement construct in explaining consumers' wine consumption behaviour is widely acknowledged in the literature, as is the social nature of dining out with others. Yet, there is a paucity of research examining the relationships between how this construct interacts with dining group dynamics and wine consumption behavioural aspects in the restaurant environment. This study aims to investigate these aspects in US restaurants. Design/methodology/approach Utilising an online survey that yielded a sample of 513 respondents from across the USA who frequented all the recognised restaurant categories, respondents are segmented into low and high wine involvement categories using a reliable wine involvement scale. The authors examine differences between various dining group dynamics, dining group composition, main choice factors when ordering wine and method of ordering wine in US restaurants. Findings The authors find that diners' level of involvement with wine provides sharp insights into several significant differences between involvement and dining group dynamics, group composition, choice factors when ordering wine and method of ordering wine in restaurants. High involvement diners dine out in larger groups, order more wine, spend more money on wine, are more often the main decision-maker ordering wine for the dining group and use wine menus and wall board displays more often when ordering than low involvement diners. They are also more discerning about the taste of wine, grape variety and wine style in terms of choice factors when ordering. Originality/value The authors make a substantive contribution by being the first study to examine the relationships between dining group dynamics, dining group composition and behavioural aspects concerning wine consumption and involvement in the restaurant environment. The authors then map this information to derive wine-related profile descriptions for all US restaurant categories.
