Developing an integrated viticulture in the upper part of the hill Somló

Abstract

The hill Somló looks like a huge island wich jumps out of the see, a few kilometers away from the slope of Bakony highland and on the edge of the Hungarian small plane. Viticulture has started on the slopes of the hill few thousand years ago, but because of the latest technological development and economical circumstances the copartners have developed a synchronized research program. In the frame of this program we have 8 very distinctive sub-projects. The projects are including the effect of rootstock on grapevine quality, the canopy management, the order of the steps and the quality cultivation, the evaluation of site effect and row direction of the plantation, the plant protection system and the fertilization of the vineyards. Differences were obtained in sugar content related alcohol content in the crop load management experiment, in the soil cultivation and fertilization experiment. The titratable acid content also varied by treatments, we have got the lowest value (5.44 g/l) in the higher N fertilization treatment in the V. vinifera cv ‘Italian Riesling’ vineyard, while the highest value (7.93 g/l) was in the mechanically cultivated experiment among other two kind of cultivation methods in the V. vinifera cv ‘Furmint’ plantation. It was measured the pH, the residual sugar content, the sugar free dry matter content and phenol compounds in a few experiments. Row direction, rootstocks crop load management, soil cultivation methods, and fertilization are very influential in the quality production as our results shows.

Double success of combining technical management with low pesticide inputs in the vineyard to obtain PDO wines in France

Viticulture is a major contributor to the antagonism of positive reputation and negative environmental impacts of agriculture. Vine contributes to structure landscape in the world, resulting, for example, in the delimitation of protected designations of origin (PDO). PDO vine is currently subject to the double challenge of sustainability and climate change adaptation. As vine is very sensitive to diseases and pests, vine requires a high use of pesticides to achieve its quality and yield goals. This high need for pesticides is the most important negative impact of environmental components.

Polyphenol content of cork granulates at different steps of the manufacturing process of microagglomerated stoppers treated with supercritical CO2 used for wine bottling

The wine closure industry is mainly divided into three categories: screw caps, synthetic closures, and cork-based closures. Among this latter, microagglomerated cork stoppers treated with supercritical CO2 are now widely used, especially to avoid cork taint contaminations[1]. They are designed with cork granules obtained from cork offcuts of the punching process during the natural cork stoppers production. A previous study[2] showed that these stoppers released fewer polyphenols in 12 % (v/v) hydroalcoholic solution than natural cork stoppers.

The potential of some native varieties of Argentina for the production of sparkling wines. Effect of lees contact time 

Grapevine varieties from South-America, commonly known as criollas, originated because of the natural crossbreeding of grapevine varieties brought by the Spaniards. The objective of this work was to evaluate the potential of some varieties to produce sparkling wines considering the effect of lees contact time. The following varieties were used: Moscatel Rosado, Criolla Chica, Pedro Gimenez, Blanca Oval, Canelón, and the European variety Chardonnay (control), planted in the ampelographic collection of EEA Mendoza INTA (Argentina). Pilot-scale vinifications were carried out to obtain the base wines, in 20 L glass containers. The second fermentation was performed through the traditional method.

The tolerance of grapevine rootstocks to water deficit is related to root morphology and xylem anatomy traits 

Climate change is altering water balances, thereby compromising water availability for crops. In grapevine, the strategic selection of genotypes more tolerant to soil water deficit can improve the resilience of the vineyard under this scenario. Previous studies demonstrated that root anatomical and morphological traits determine vine performance under water deficit conditions. Therefore, 13 ungrafted rootstock genotypes, 6 commercial (420 A, 41 B, Evex 13-5, Fercal, 140 Ru y 110 R), and 7 from new breeding programs (RG2, RG3, RG4, RG7, RG8, RG9 and RM2) were evaluated in pots during 2021 and 2022.

PHOTO OXIDATION OF LUGANA WINES: INFLUENCE OF YEASTS AND RESIDUAL NITROGEN ON VSCS PROFILE

Lugana wines are made from Turbiana grapes. In recent times, many white and rosé wines are bottled and stored in flint glass bottles because of commercial appeal. However, this practice could worsen the aroma profile of the wine, especially as regards the development of volatile sulfur compounds (VSCs). This study aims to investigate the consequences of exposure to light in flint bottles on VSCs profile of Lugana wines fermented with two different yeasts and with different post-fermentation residual nitrogen.
