Terroir aspects in development of quality of Egri bikavér

Abstract

Egri Bikavér (Bull’s Blood) is one of the most remarkable Hungarian red wines on inland and foreign markets as well. From the end of the 70’s the quality of Egri Bikavér was decreasing continually due to mass production. The concept of production of quality wines became general in the mid 90’s again and it resulted in a new Origin Control System, for the first time that of Egri Bikavér in Hungary. In the present study, the effects of different terroirs on wine quality are discussed in the case of Kékfrankos (Blaufränkisch) variety, which is the main component of the blending of Egri Bikavér. The experiments have been carried out in Eger wine region of Hungary. Soil characteristics, mesoclimate and phenological stages were examined at six growing sites. Grapevines in extreme growing sites were described with plant physiological parameters (net photosynthesis, water relations) and canopy structure was also studied. The grapes were harvested at the same time and winemaking technology was the same as well. Beyond the routine chemical analyses, the contents of anthocyanins and polyphenols were also analysed. During the sensory evaluation, the wines were described with radar plots of various parameters.

Remarkable differences were found between the growing sites based on the results of sensory and laboratory analyses. The differences can be explained by the results of soil properties, microclimate and plant physiological measurements. The results of this work may be helpful when the appellation origin control system of Egri Bikavér Superior Eger and Egri Bikavér Grand Superior « terroir » are to be developed.

Enological evaluation of the attitude of the grapevine fumin to give varietal wines

Initiatives have been ongoing in recent years to safeguard biodiversity in the oenological sector via a process of enhancement of ancient varieties, under a pressure of a market strongly oriented towards production deriving from native vines of specific geographical zones. In that sense, Aosta Valley
(Italy) has raised the need to preserve and characterize its minority vine varieties which have the potentiality to give varietal wines. Fumin represents the 7% of the production of the region with 16 hectares of vineyards and 753 hectolitres of derived wine. Due to its large phenolic potential, strong astringency and deep colour, it has long been, and is still today, assembled or blended with other varieties as occurs, for example, for the Torrette.

Comparison of plant nutrients in the soil solution and bleeding sap of grapevine cvs

In this study macro and micro nutrients of plants (N = NH4 + NO3 , P, K, Ca, Na, Zn, Mn, Fe and Cu) were determined both in soil solution and bleeding sap and compared each other. Bleeding sap was collected from the nine varieties of grapevine Cvs. grafted on 5BB rootstock and grown in different soil conditions. For all varieties, plant nutrients content in bleeding sap as higher than in soil solution except for Ca and Na. While in soil solution Ca content was found at 10209 ppm, this value in bleeding sap was 49.20 ppm (Kozak Beyazy), 55.38 ppm (Trakya Ylkeren), 50.37 (Cardinal) and 74.27 ppm (Tekirdaô Çekirdeksizi) respectively. For the same varieties the Na values were as follows : 7.16 ppm (in soil solution) : 4.8, 3.23, 4.21,4.58 ppm (in bleeding sap) respectively. K content in bleeding sap was higher than in soil solution for a few varieties, and lower in some varieties. Traces of Fe and Cu were found in both media.

Grapegrowing soils

The soil plays a key role in viticulture since it defines the planting depth, development and aeration of the root system and also controls the absorption of mineral elements and water conditions of the plant

Impacts of the projected changes in temperature under scenarios of climate change on vine phenology of three red varieties cultivated in Rioja (Spain)

Grapevine is one of the crops that may suffer more negative impacts
under climate change, due not only to changes in temperature but also due to water available. Some of the most direct effects of climate variability on grapevines are the changes in the onset and timing of phenology events and changes in the length of the growing season, which may have further effects on grape quality. The aim of this research was to analyze the changes in vine phenology of some red varieties (Tempranillo, Grenache and Carignan) cultivated in Rioja Oriental (Rioja DOCa), under different climate change scenarios.
