Organic wine purchase behaviour in Germany: Exploring the attitude-behaviour-gap with data from a household panel

Consumer surveys revealed positive attitudes towards organic wine in large consumer segments. Health, environmental and quality benefits were stated most often as drivers for purchase decisions. However, sales data show that the market share for organic wine is still far below 10% compared to the total wine market in all countries. Obviously, there is a gap between consumers' attitudes and real purchase behaviour in daily decisions. So far, it is not clear whether there is congruence between consumers' attitudes and their purchase behaviour and if the attitude-behaviour-gap differs among consumer segments. Consequently, the paper at hand explores the attitude-behaviour-gap with household panel data from the GfK Group by means of a cluster analysis. The results show that even though expenditure shares for organic wine were at a low level, attitudes were in line with purchase behaviour for five out of six clusters. For example, consumers who had the highest expenditure share for organic wine showed strong pro-environmental attitudes and a preference for sustainable products. Therefore, comprehensive communication about sustainability issues, which also includes social aspects, could help to further develop the organic wine market and lead to higher market shares. However, for the low-income consumer cluster, the price of organic wine seemed to be an effective barrier despite their positive attitudes towards environmentalism. Future studies need to consider that the extent of the attitude-behaviour-gap is segment specific.
