Optimization of in vitro establishment of grapevine varieties for fast micropropagation 

Grape phylloxera (GP) (Daktulosphaira vitifoliae Fitch, 1855) devastated European vineyards in the 19th century by attacking Vitis vinifera roots. Today, grafting onto resistant American rootstocks remains its primary control strategy, but GP continues to threaten non-grafted vineyards, prompting the search for alternative control solutions.

The use of multivariate statistics to correlate chemical data to spectral information seems as a valid alternative for the quantification of red wine phenolics. The advantages of these techniques include simplicity and cost effectiveness together with the limited time of analysis required. Although many
publications on this subject are nowadays available in the literature most of them only reported feasibility
studies. In this study 400 samples from thirteen fermentations including five different cultivars plus 150
wine samples from a varying number of vintages were submitted to spectrophotometric and chromatographic phenolic analysis.

In this video recording of the IVES science meeting 2021, Benjamin Bois (Institut Universitaire de la Vigne et du Vin – IUVV, Université de Bourgogne, Dijon, France) speaks about zoning the climatic potentialities and risk of vineyards & wine production regions.

One cultivar could produce distinct wines with typical properties and qualities different depending on its cultivated and its mesoclimatic conditions.

The wine sector is being directly affected by climate change. Temperatures above 30ºC can cause a lag between the ripening of the berry pulp (a rapid increase in sugar content) and the skin
