Identifying research opportunities at Douro Demarcated Region

Abstract

The Douro Demarcated Region, in Northern Portugal, offers outstanding wines with unique characteristics. Due to the today’s globalized marketplace, local producers often need to further develop their cultivation techniques to remain competitive. The Association of Viticultural Development in the Douro Valley (ADVID) works as a unit of experimentation, offering services and training to meet the demands of the Douro’s vitiviniculturists. In 2009 the Association was promoted as “Douro Wines Cluster” by the Ministry of Economy of Portugal. That act requires an integrated plan to increase the level of technical and economical competence of the sector, as a differential of competitiveness for enterprises in the country and worldwide.
As a consequence, this work results in the creation of an action plan that represents the interests of members of ADVID. Therefore, in order to identify the producer’s technical constraints, a qualitative survey was conducted, from April to August 2009 with members of the Douro Wines Cluster. That survey brought together a representative set of stakeholders, taking into account distinct member’s profiles in terms of area under vineyards and location. The work identified 39 overriding Research and Development necessities for the region. The final list provides general guidelines to steer strategic research which are deemed to be the most relevant for the development of the Douro wine cluster.

Grapevine sensitivity to fungal diseases: use of a combination of terroir cartography and parcel survey

In front of the economic interest and seeking to respect their environment, the wine growers move gradually towards a policy of reasoning their plant health protection. This is why, starting from epidemiologic studies on grapevine pathogens, forecasting models of the risks are developed by research and experimentation bodies.

Determination of titratable acidity, sugar and organic acid content in red and white wine grape cultivars during ripening by VIS–NIR hy¬perspectral imaging

Grape harvest time is one of the most fundamental aspects that affect grape quality and thus wine quality. Many factors influence the decision of harvest; among them technological and phenolic maturity of grape. Technological ripeness is mainly related to sugar concentration, titratable acidity and pH. Conventional methods for chemical analysis of grapes are normally sample-destructive, time-consuming, include laborious sample preparation steps, and generate chemical waste, thereby limiting their utility in online/in-line quality monitoring. Moreover, destructive analyses can be performed only on a limited number of fruit pieces and, thus, their statistical relevance could be limited. This study evaluated the ability of a lab-scale hyperspectral imaging (HYP-IM) technique to predict titratable acidity, organic acid and sugar content of grapes. Samples of Cabernet franc and Chenin blanc grapes were consecutively collected six times at weekly intervals after veraison. The images were recorded thanks to the hyperspectral imaging camera Pica L (Resonon) in a spectral range from 400 to 1000 nm. Statistics were performed using Microsoft Xlstat software. Successively, the berries were analyzed for their sugar (glucose and fructose) and organic acid (malic and tartaric acid) content and titratable acidity according to usual methods.
