Sélection génétique des variétés originelles d’Arménie, berceau de la viticulture mondiale

Abstract

L’Arménie, petit pays du Caucase du sud, redécouvre son passé viticole depuis la mise à jour en 2007 de vestiges archéologiques viticoles datant de 6000 ans environ. Ces vestiges comptent parmi les plus anciens dans le monde. Malgré une grande diversité de cépages, les vignerons arméniens ne disposaient pas de collections génétiques suffisamment organisées pour produire des plants et satisfaire la demande croissante de plantation.
Les premiers travaux de prospection et de mise en collection ont débuté en 2012 et la disponibilité en greffons est maintenant suffisante pour lancer les étapes de multiplication. Les plants sont multipliés francs de pied pour les zones de montagnes ou bien greffés pour les zones de plaines.
Le présent article retrace les étapes d’un projet en cours, de sélection et de multiplication des cépages oubliés arméniens. Il recense et analyse les difficultés – techniques, humaines ou éthique – rencontrées au cours de ce projet ambitieux et unique.

Genetic selection of original varieties from Armenia, birthplace of world viticulture

Armenia, a small country in the south of the Caucasus, has been rediscovering its wine-growing past since the discovery in 2007 of archaeological wine-growing remains dating back around 8,000 years. They are among the oldest in the world. Despite a great diversity of grape varieties, armenian winegrowers did not have sufficiently organized genetic collections to produce plants and satisfy the growing demand for planting. Initial prospecting and collection work began in 2012 and the availability of grafts is now sufficient to launch the multiplication stages. The plants are propagated free of vines for mountain areas or grafted for plain areas. The proposed article traces the stages of selection and multiplication of forgotten armenian grape varieties; it highlights the difficulties – technical, human or ethical – encountered throughout this incredible project.

Genetische selektion ursprünglicher sorten aus armenien, der wiege des weltweiten weinbaus

Armenien, ein kleines land im süden des Kaukasus, entdeckt seit der entdeckung archäologischer weinbaureste, die etwa 6.000 jahre zurückreichen, im jahr 2007 seine weinbauvergangenheit wieder. Sie gehören zu den ältesten der welt. Trotz der großen vielfalt an rebsorten verfügten die armenischen winzer nicht über ausreichend organisierte genetische sammlungen, um pflanzen zu produzieren und die wachsende nachfrage nach anpflanzungen zu befriedigen. Die ersten prospektions- und sammelarbeiten begannen im jahr 2012 und die verfügbarkeit von transplantaten reicht nun aus, um die vermehrungsphasen einzuleiten. Für berggebiete werden die pflanzen rebenfrei vermehrt oder für flachlandgebiete veredelt. Der vorgeschlagene artikel zeichnet die stadien der auswahl und vermehrung vergessener armenischer rebsorten nach; es verdeutlicht die schwierigkeiten – technischer, menschlicher oder ethischer art –, auf die man bei diesem unglaublichen projekt stößt.

“Gentle” sustainable extraction from whole berry by using resonance waves and slight over CO2 overpressure

The traditional methods of grape extraction of enochemical compounds use very often mechanical energy by pistons such as the pigeage or mechanical energy produced by must (delestage, pumping over). Recent trend by winemaker is trying to introduce in the fermentation tank, whole berry grape to avoid even minimal oxidation. Unfortunately, the use of the traditional mechanical techniques aforementioned, very often do not guarantee the optimal extraction with residual sugars in the marc. Use of resonance waves (airmixingtm) and a slight overpressure by CO2 (adcftm) permit to work on whole berry guaranteeing the perfect extraction.

Quantitative and qualitative changes in terpenes during enzymatic maceration and fermentation in wine production: insights from Polish grape varieties

The production of fermented alcoholic beverages involves numerous processes in which microorganisms and enzymes convert components derived from the raw material into a wide range of compounds that affect the sensory characteristics of the resulting product. It is estimated that there may be as many as 800 to 1,000 such compounds in wine. These compounds belong to different chemical groups such as esters, alcohols, carboxylic acids, carbonyl compounds, polyphenols, sugars and many others.

Oenological potential of wines and agronomical characterisation of grapes from five white resistant Italian varieties at Serra Gaúcha, Southern Brazil

Rio grande do sul is the main grape producing state in Brazil, with the largest wine-growing area, responsible by 90% of the national production of wines and grape juices. Serra Gaúcha is the main vitivinicultural region, where around 15% of the area is destined to produce wines from vitis vinifera L. grapes. This region presents high rainfall during the grape maturation cycle, a factor that leads to great risk of attacks by fungal pathogens. the use of resistant varieties can reduce the cost and quantity of spraying, improving wine quality, focusing on a sustainable vitiviniculture.

Evolution of the metabolic profile of grapes in a context of climate change

In the current context of global climate change, anticipating the evolution of the oenological potential of emblematic grape varieties of regions such as Burgundy and Champagne is a guarantee of the sustainability of a sector which has considerable economic weight. however, if various models of climate change cast doubt on the sustainability of these grape varieties in these regions, appellation decrees, as well as consumer expectations, do not allow or consider the use of alternative grape varieties. In addition, control/compensation methods such as irrigation are also not permitted.

Legal and economic evolution of the Japanese wine industry in the 21st century

Historically bounded by strict regulations with a focus on taxation since the 19th century, the japanese wine industry stands at a crossroads in the 21st century, necessitated by alignment with international standards and opening towards global markets.
