One of the challenges of grape production is grapevine health, which annually forces the winegrowers to incur fixed costs associated with the prevention and/or treatment of pests and diseases, causing an impact on the environment due to the application of phytosanitary products. Among the various diseases affecting grapevines, downy mildew (Plasmopara viticola) stands out, which causes negative impacts throughout the phenological cycle, particularly on leaves by affecting the absorption of photosynthetic pigments and consequent chlorophyll production, ultimately influencing grape yield and quality. Traditional methods for detecting vineyard diseases are often insufficient in crop protection, favoring new forms of a more agile decision support with timely responses. Proximal sensing trough optical sensors can assist in early disease detection. In this context, thermal infrared sensors stand out for their ability to capture changes in thermal response of leaves due to changes in grapevine metabolism and photosynthetic production.

Further, the study aims to check possible differences in the valued attributes regarding consumer’s involvement level and wine Region Origin. The research was designed to identify relevant wine attributes and measure their importance when choosing a wine. In order to achieve this objective and match it with consumers’ involvement and wine origin region, 30 Focus Groups were performed, involving 171 consumers from five Portuguese regions of origin 2014-01-01T00:00:00Z
