Bodega Cuatro Rayas promotes an archaeoenology and R&D project to increase the longevity of Verdejo

‘Longverdejo’ aims to improve access to the international market for aged white wines and involves the use of new strategies such as the selection of native yeasts or the implementation of environmentally friendly viticultural techniques

Develops a project in collaboration with the Research Institute of Vine and Wine (IIVV) of the University of León and is co-financed by the CDTI with FEDER funds

La Seca, May 26, 2020.- The Bodega Cuatro Rayas cooperative has launched the Longverdejo activities, an R&D project whose objective is to increase the longevity and aging capacity of white wines of the Verdejo variety. Under the title ‘Study of the longevity of the Verdejo variety in the DO Rueda through soil management, vineyard management and archaeoenology’, this initiative will develop different and innovative strategies that include novel soil and plant management techniques. , as well as a selection of native yeasts from wineries where nature has always predominated. All this to try to influence the most important oenological parameters in order to improve the longevity potential of Verdejo wines, increasing their commercial useful life and the possibility of using the wine for aging.

Bodega Cuatro Rayas develops this project in which researchers from the Research Institute of Vine and Wine (IIVV) of the University of León also participate with the Research group of Dr Enrique Garzón. The initiative has a global budget of € 599,000 and is co-financed by the CDTI with ERDF funds from the European Union through the Multi-regional Operational Program for Smart Growth 2014-2020. Longverdejo has an expected duration of 36 months, between September 1, 2019 and August 31, 2022.

FOCUS ON SUSTAINABLE VITICULTURE

To meet Longverdejo’s general objective of increasing the longevity of Verdejo wines, different and innovative strategies will be developed that include the selection of native yeasts from underground cellars and the implementation of new sustainable viticulture techniques. New methods of fertilization with iron sulfates in combination with peat and / or leonardites will be used as soil management techniques. Plant management techniques will also be used to increase the acidity of the musts, as well as new methods of ecological phytosanitary control in order to achieve the compositional balance necessary in the musts for the production of longer-lived white wines.

The first application phase of the project consists of identifying the physical-chemical and biological characteristics of the soils where the tests will be carried out to determine the appropriate doses of organic fertilizer, using a product developed by the IIVV in collaboration with the Agroquimes company, and more Later on, foliar treatments will be applied and in the harvesting processes, as pointed out by Raúl Diez -grower partner and vice president of the cooperative-. The fermentation of some winery musts has also begun to be studied naturally and without additives in underground wineries located in Valladolid and Segovia to try to identify the yeast strains originating in these areas and check how they express their character in the wines, such and as stated by Roberto L. Tello -enologist of the cooperative-.

The great potential presented by the Verdejo variety grape to produce long-lived white wines has not been sufficiently explored so far, as Enrique Garzón -professor at the University of León and IIVV researcher- and José Martín -technical director of the Bodega Cuatro Rayas vineyard. The production of great white wines with a longer shelf life constitutes one of the points of greatest interest for this DO, since it would facilitate the access of exports to areas that require long-distance wines, as well as to enter to compete internationally in the sector of the reference aged white wines. For this reason, both in aging wines and in young wines, the increase in the useful life of white wines constitutes a point of interest and very relevant improvement, which can provide great competitive advantages for the international export of wines that demand great tours. In addition, it can mean an improvement in the management and organization of resources in the wineries, allowing greater independence between production and the immediate demand for the product, as well as optimizing their distribution and storage logistics. From a commercial point of view, it is intended that the execution of this R&D project entails an increase in the export of this product.

THE AGING CAPACITY OF THE VERDEJO IN THE POINT OF VIEW OF THE DO RUEDA

The concept of shelf life in a wine is a complex concept that can be understood as the period of time during which a wine maintains its initial organoleptic characteristics or as the time that a wine remains fit to be marketed. Thus, young white wines, characterized by their freshness and fruity aroma, their pale color and delicate astringent flavor, are usually wines made to be consumed in short periods of time from their production. In another sense, it should be noted that, although white wines tend to have less capacity to evolve in the bottle than red wines, certain grape varieties show better properties for the production of older white wines. This is the case of the Verdejo variety, which, being the base of the most popular white wine in Spain, conceived as a product for annual consumption, also has the ideal characteristics to produce aged white wines and young wines with a longer shelf life.

CO-FINANCED BY CDTI WITH FEDER FUNDS

Longverdejo is an R&D project whose main objective is to increase the longevity and aging capacity of white wines of the Verdejo variety, through the development of different and innovative strategies that include the selection of native yeasts and the implementation of new techniques. of viticulture respectful with the environment. Among these techniques, new fertilization methods will be used for vineyard and plant management, as well as new methods for ecological phytosanitary control. Bodega Cuatro Rayas leads this project in which, as a subcontracted entity, the Research Institute of Vine and Wine (IIVV) of the University of León also participates. The initiative has a global budget of € 599,006.36 and is co-financed by the CDTI with ERDF funds from the European Union through the Multi-regional Operational Program for Smart Growth 2014-2020. Longverdejo has an expected duration of 36 months, between September 1, 2019 and August 31, 2022.
