Milk consumption patterns are changing in Portugal. Factors like convenience, quality and safety increasingly constitute the basis for the Portuguese consumer purchasing decision. Demand for organic milk products (OMP) is emerging while most of these products are supplied by foreign companies. This study explores the demand for OMP in Portugal using both direct market observation and multivariate methods, in particular factor and cluster analysis. It appears that there are specific emerging segments preferring OMP, as they are increasingly concerned by health attributes and environmental protection.
