Description
BODEGAS PRÍNCIPE DE VIANA is a winery dedicated to the elaboration, selection and commercialization of quality wines under Guarantee of Origin and Quality of Navarre. Information shows that Climate Change can greatly influence and determine the vineyard cultivation. Few studies have analyzed the combined effects of temperature, dry and carbon dioxide increment; which determine yearly the production and quality of the grape. On the other hand, the Hydric and Nutrient Management affects both, directly and indirectly the vineyard’s physiology. Therefore, the production and composition of the grape are affected. Thus, with this project, the company will tackle the adaptation of viticultural to Climate Change, setting the overall strategy for vine growing and the optimization of oenological process: efficiency of water and nutrient resources across different techniques, minimizing energy consumption and increasing the sustainability. To achieve the project purposes, we will cooperate with a Norwegian partner: WORLD WINES AS (part of the Norwegian Beverage Group) working on the study of the needs and results validation.
Summary of project results
The production and composition of the grape are affected by climate. So it is important to control them as the quality of the harvest is determined by them. The company has tackled the adaptation of viticultural to the Climate Change, setting the overall strategy for vine growing and the optimization of oenological process: efficiency of water and nutrient resources across different techniques, minimizing energy consumption and increasing the sustainability. The project has developed the following research lines: •Research on the effects of simultaneous interaction of hydric stress and high temperature on the grapevine physiology. •Best practices management for sustainable and environmentally friendly grape and wine growing. The main results have been: •Reduce water costs by 25-35% •Reduce energy consumption by 20-30% •Improve the quality of wines •Decrease irrigation needs 62.5% •Improve aromatic intensity, it made remarkable since the summers are getting hotter
Summary of bilateral results
In order to validate the results, tastings were carried out throughout the production process. Once the process is complete, final tastings were conducted to draw conclusions from the work done. These tasting was conducted by experts from WORLD WINE AS (partner company in Norway). In this way it was found that it can still improve on sustainability, without have to sacrifice quality and even to improve it.
