Effect of row direction in the upper part of the hillside vineyard of Somló, Hungary

Abstract

Hillside vineyards have a great potential to produce world class wines. The unique microclimate lead to the production of rich, flavory wines. However site development needs land clearing, rock removal, terracing, engineered water collecting drainage system. Because of the very high cost of establishment every part of the plantation needs to be very carefully planned, designed and established. Row direction has a pronounced effect on sunlight interception. The amounts of direct light are absorbed by the canopy is influenced by the row direction. Commonly known that greater amounts of light absorbed by the canopy the mid-morning and mid-afternoon in rows directed north-south compared to east –west. But information on the effects of row direction on the fruit quality of grapevines are limited. Therefore we established an experiment on hill Somló to determine if row direction has role to improve the quality or not. We have 24 % less yield, higher sugar content, lower acid content in row direction east-west compared to the north-south in 2006. Similar results were obtained in 2007 as well. The catechin contents differed statistically only among other poliphenols between the row directions. The wine analysis and organoleptical evaluation showed that the east-west oriented rows produced better quality of wine in 2006. We have very extreme weather conditions in 2007 in July and August therefore we have not got the same picture in 2007 like in 2006. Even if we have only two year results the clear influence of row direction pictured on the quality of the yield.

Contribution of grape seeds to evolution of acetaldehyde, pigments and tannins reactive towards salivary proteins of red wine over time

This study investigated the impact of the gsk/gse ratio on the evolution of acetaldehyde and of major phenolic compounds of aglianico wine in wine like solution and real wine. Four model solutions and the correspondant control wines were prepared. The natural weight ratio between grape skins and seeds was determined on the real grapes, and a control wine was obtained from those.

Dans les études des terroirs, il est souvent délicat d’établir des zonages et de mesurer les effets de l’environnement sur les vins. Avec plus d’un million d’hectares dans l’aire d’appellation délimitée, le terroir du célèbre vignoble de Cognac est bien connu pour ces eaux-de-vie et ainsi divisé en 6 crus.

Bunch placement effects on dehydration kinetics and physico-chemical composition of Nebbiolo grapes

Sforzato di Valtellina DOCG is a special reinforced red wine produced using withered Nebbiolo grapes. The withering process takes place in traditional rooms under natural environmental conditions; it starts immediately after the harvest and ends not before the 1st December of the same year. The process can be performed with different bunch placements that can influence the grapes features.The purpose of the study is to compare the effect on grape physico-chemical parameters for four withering bunch placement systems: hanged clusters (HC), plastic crates (CT), breathable mesh fabric on wooden frames panels (MF), and reed mats (RM). For all the systems studied, the withering length was two months at a temperature between 6 and 19 °C and a relative humidity of 41-88%.
