Obtaining new varieties derived from Monastrell for the preparation of low alcoholic wines

Abstract

The main challenge faced by viticulture is to improve the quality of the wines, adapting them to the new consumer demands that demand wines with lower alcohol content and greater freshness. In the last 30 years, a clear modification has been observed in the composition of the grape due to climate change, showing a higher sugar content due to an excess of maturity, giving rise to wines with a higher alcohol content, less organic acids, a higher pH high, and a lower anthocyanin content and, therefore, lower color (van Leeuwen and Destrac-Irvine, 2017).

There are different strategies to achieve wines with a lower alcohol content, one of them would be to obtain new varieties that can adapt to harsher growing conditions than the current ones and that are capable of producing quality grapes and wines. In 1997, a program of crossings directed from the Monastrell variety began at IMIDA. At present, a new line is being started in which the selection of hybrids that accumulate few sugars in the pulp and therefore suitable for the production of wines with a low alcohol content has been carried out.

In 2017, 6 red hybrids of “low alcohol content” were selected from crosses between Monastrell, Syrah and Cabernet Sauvignon, of which 20 strains of each were planted. This year for the first time they have entered production and have been able to be elaborated. The grapes were harvested on August 25 with a ºBrix between 21 and 23, and the CI of the wines obtained at the end of alcoholic fermentation is between 40 and 62 color points. The results, although still preliminary, may be very promising for the future of viticulture.

Gamma-ray spectrometry In Burgundy vineyard for high resolution soil mapping

Aim: A soil mapping methodology based on gamma-ray spectrometry and soil sampling has been applied for the first time in Burgundy. The purpose of this innovative high-resolution mapping is to delimit soil areas, to define elementary units of soil for terroir characterization and vineyard management. The added value of this integrated approach is a continuous geophysical mapping of the soil with an investigation depth of 60cm.

Deficit irrigation and mechanical canopy management affect berry and wine phenolic and aroma composition of Syrah in Central California

Labor shortage is one of the most crucial issues in current viticulture. Mechanized approaches are helpful in reducing production costs and increasing vineyard efficiency but their effect on grapes and wines needs evaluation. This work assess the results of combined mechanical pruning and shoot thinning with deficit irrigation strategies to reduce management costs but not quality of production.

The effects of cover cropping systems on vine physiology, berry and wine quality in a climate change scenario in Switzerland

Sustainable weed control with little detrimental effects on vine physiology, yield, berry quality, soil structure, health and biodiversity is a key factor in vineyard management. Few options are available to avoid herbicide utilization and minimize negative effects of frequent tillage on soil quality. The present project aims to investigate and develop different cover management strategies in a cool climate viticultural region in Switzerland. The impact of different treatments on vine, must and wine has been studied in an experimental vineyard in Changins, Switzerland for one year and will be continued over the next three years.

Extension to the Saumurois-Touraine area of an Anjou-originated method for the characterisation of the viticultural terroirs. (Loire Valley, France)

En Anjou, une méthode de caractérisation des terroirs viticoles a été développée. Elle utilise un modèle de terrain basé sur la profondeur de sol et son degré d’argilisation. Le modèle concerne des terrains issus principalement de roches mères métamorphiques et éruptives du Massif Armoricain. Cet outil de caractérisation des terroirs viticoles nécessite d’être adapté lorsqu’il s’agit d’ensembles géologiques très différents, en particulier sur sols d’apport et de roches mères tendres et poreuses du Bassin Parisien. Une meilleure compréhension de la réserve hydrique des sols apparaît être un critère important de l’interaction entre le milieu et la plante.

Analysing consumers’ decision-making process for non-alcoholic spirit drinks and dehalcolized aromatized wines 

In recent years, the consumption of alcoholic beverages is changing, driven by evolving consumer preferences and societal trends, including a wave of health consciousness. Among these changes, the emergence and proliferation of nolo (no alcohol/low alcohol) alcoholic beverages have gained significant attention within the industry. Nolo alcohol beverages are produced to emulate the appearance, aroma, and taste of alcoholic beverages, potentially facilitating a sense of social integration when consuming a product that closely resembles alcohol.
