Abstract: Vineyards represent one of the main crop systems of greatest importance in the world economy, both in terms of the
value chain of wine production and in its current expression of generating tradable goods. 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.

Abstract: The purpose of this presentation is to identify and understand the relevant attributes,
both extrinsic and intrinsic, that Portuguese consumers value and are relevant in the decision
process for choosing wine.
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 origin2014-01-01T00:00:00Z
