«Nektar» -the new red variety wine grape aromatic high quality

Abstract

Context and purpose of the study – The multi-annual study of the International Genetic Bank of the Grape Vine has shown that red varieties are enough, but the red varieties that produce high-quality red wine are minimal. This paper presents is the create, the study and amplographic description the new red variety “Nektar”. The new red variety “Nektar” was created at the Athens Vineyard Institute in 2012.  

Material and methods – The variety created by crossing by the method of hybridization of the newly Greek variety “Makedonas” (“Ksinomauro” x “Cabernet Sauvignon”) with the newly Greek variety “Tihi” (“Augoulato” with the pollen mix of varieties Cabernet-Sauvignon and Grenache noir).

Results – The “Nektar” is is a new red grape variety wine-making quality aromatic. The duration of the variety from budburst to maturity is 136-145 days. The variety is very strong with large shoots growth (2.1 – 3.0 m). The growth of shoots is higherover 95 %. The average mass of cluster is 360 g and the yield are high, 15-20 t / ha. The “Nektar” grape variety is medium, spheric,middle density, the diameter 15 mm, with anaverage weight of 1,9 g and a blue-black color.The flower is hermaphrodite. The pollen is fertile.The quantity of seeds in berry is3-4. The skin is thick with high strength. The flesh isnone or very weak, with a special flavor of the variety, green paper. The content of sugar in must is greater than 24 %. The “Nektar” variety, based on its ampelographic and natural characteristics, is classified in the group of varieties convarietasponticaNeqr. It is distinguishedfrom by its high resistance to drought and fungal diseases compared to other varieties of Vitis vinifera L. The variety is intended for the production of high-quality red wines, and very aromatic juices. Can be used in the genetic improvement of vitis vinifera varieties as a qualitydonor

Les outils pour favoriser le renouvellement des générations en viticulture

French lawmakers have chosen the family-type winegrowing business as the benchmark for drafting the legal framework for winegrowing businesses and winegrowers. In france (source: msa), in 2022, there were 1,444 new winegrowers, an increase of 3% compared with 2021, representing 10% of new farm managers. The retention rate for winegrowers is 75% (up 13% on 2021), compared with 77% for all agricultural sectors (stable).

The film-forming Pichia spp. in a winemaker’s toolbox: A simple isolation procedure and their performance in a mixed-culture fermentation of Vitis vinifera L. cv. Gewürztraminer must

Certain yeast species belonging to the Pichia genus are known to form a distinctive film on grape must and wine. In a mixed-culture type fermentation, Pichia spp. (P. kluyveri in particular) are known to impart beneficial oenological attributes. In this study, we report on an easy isolation method of Pichia spp. from grape must by exploiting their film-forming capacity on media containing 10% ethanol. We isolated and identified two Pichia species, namely Pichia kudriavzevii and Pichia kluyveri, and subsequently co-inoculated them with Saccharomyces cerevisiae to ferment Gewürztraminer musts. Noteworthy differences included a significant increase in the 2-phenethyl acetate levels with the P. kluyveri co-fermentation and a general increase in ethyl esters with the P. kudriavzevii co-fermentation. Both Pichia co-inoculations yielded higher levels of glycerol in the final wines. Based on all the wine parameters we tested, the P. kluyveri strain that was isolated performed similarly to a commercial P. kluyveri strain.

Implications of the nature of organic mulches used in vineyards on grapevine water status, yield, berry quality and biological soil health  

Climate emergency is going to affect the agricultural suistainability, wine grapes being probably one of the crops more sensitive to environmental constraints. In this context, mitigation strategies such as the revalorization of agricultural wastes are paramount to cope with the current challenges. The use of organic mulches has been reported to reduce soil water evaporation and improve vine water status, reduce soil erosion, and increase soil organic matter with little impact on berry quality. However, less is known about their effects on the microbiote of vineyards.
