Project Summary

In August 2009 was fully implemented the reform of the Common Market Organization for wine (CR Nº479/2008, 29-04-2008). It aims at reducing the 24 million hl/year surplus of basic low quality wine, phasing out the €500 million/year spent on wine disposal subsidies and making EU wine more competitive. This reform, the inevitable disappearance of EU subsidies together with the recent economical crisis, more demanding consumer trends, the competition of New World producers and the uncertainties caused by climate change, will put out of business many EU winegrowing SMEs in the following years. 

To survive, EU winegrowers will have to increase crop value (grape quality), reduce the production volume of basic wine and convert part into premium quality. This can be achieved by implementing effective field control methods that avoid the common problem of mixing under-ripe and over-ripe grapes, main cause for the production of poor quality wines.  To solve this problem, an European Project called PREMIVM (www.premivm.eu), was setup by an international consortium coordinated by the Portuguese company Agriciência.

PREMIVM proposes a solution based on proven laboratory experimentations performed by partners of the consortium: a low-cost, handheld device capable of non-invasively estimating sugars, chlorophyll, polyphenols and nitrogen in grapes and leaves. All this in the vineyard, by means of the innovative use of chlorophyll fluorescence and reflectance multispectral data correlated by specific mathematical models, with GPS tags for all readings. The measurement principle is based on the natural response of vegetal species to light, where specific molecules are excited at a certain wavelength and emit radiation of a different wavelength.

The emission spectrum provides qualitative and quantitative data that can be used by vineyard managers to precisely control the field, reduce vineyard variability, define optimal harvesting times and increase production value.
