Abstract

In the last decade the demand for wine in Italy has contracted a considerably linked to changes in eating habits and in the evolution of consumption patterns. These developmental aspects in the buying habits of consumers are linked to socio-economic changes that have affected the Italian economy. The new patterns of consumption have shown a trend by consumers towards better quality wine products. The preference for high quality products has caused a contraction in total consumption bye switching from daily consumption to occasional consumption. The aim of this work is to trace the major factors in the main wine consumption habits and patterns and to verify the degree of knowledge of height quality wines with original brands. The methodology followed to conduct the research project was quantitative and random. The random search refers to the identification of the prominent factors from which springs the buying behavior of consumer. The tool used for processing data consisted of the creation of a double entry table and estimation of the log-likelihood ratio test with relative p-value. The fixed level of significance for the overall statistical analysis was alfa = 0.05. The log-likelihood ratio test, referred to in statistics literature as the G test, was used to evaluate the association between the two qualitative variables. In order to assess whether the frequency of wine consumption is significantly influenced by age was estimated by ordinal logistic regression model.
