Modelling Consumer Choice Behaviour: A South African Wine Case
Increased product diversity and changing consumer demands require marketers to gain an in-depth understanding of consumer behaviour and choice – a fundamental outcome of the consumer purchasing process. Consumer behaviour is influenced by several internal and external factors, including perception and motivation (internal), and culture and marketing elements such as price and product (external). Consequently, the analysis of attribute-based product choice contributes to market and product development. The increased number of wine brands, choice of wine styles and prices as well as the complexity of wine attributes (intrinsic, relating to actual product and extrinsic, relating to variety, brand name, etc.) motivated this study. The purpose of the study was to investigate consumer choice behaviour pertaining to the extrinsic product attributes of South African wines. Primary data collection included wine consumers (minimum 18 years old; purchased wine before). A fractional experiment was used to investigate wine consumers’ attribute-based choices. Thirteen attributes were selected based on various global and local studies. A questionnaire with a best–worst measurement scale and balanced incomplete block design was utilised to gather data via social media (Facebook). Using judgement sampling, 300 responses and an additional 100 responses, after adding a screening question for premium wine consumers (paid minimum R200/bottle), were obtained. The results showed a significant difference between wine attribute scores, and “Tasted the wine previously” ranked the highest, followed by “Someone recommended it”. This study’s findings differ somewhat from those of similar global studies, given that “Origin of the wine” and “Brand name” received higher rankings in these studies. The main insights of the study may improve understanding of attributes influencing wine-buying behaviour and the influence of price effects.
