A preliminary study of the relationship between Australian wine consumers' wine expertise and their wine purchasing and consumption behaviour

Few Australian wine companies have the resources to acquire consumer relevant information to assist their strategic decision-making. This exploratory study examined the relationship between Australian consumers' wine expertise and their self-reported wine related behaviours, such as wine purchasing and consumption. A measure of consumer wine expertise developed specifically for the Australian consumer, comprising a wine knowledge test and an aroma identification (sensory) test, was used to segment 61 wine consumers into three expertise levels. A large positive correlation between wine expertise and formal wine training was demonstrated. Data showed that females dominated the low and males the high expertise groups, respectively. The high expertise level consumers spent more on wine, purchased more bottles and fewer casks per month and consumed more wine in a week than the low and medium expertise groups. Analysis revealed significant differences between the styles of wine consumed by the various expertise levels. A combination of Factor and Cluster analyses generated three distinct consumer segment profiles based on wine purchase drivers. These preliminary data indicate that wine consumers' wine behaviour may be influenced by their wine expertise.
