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.

Heat requirements for grapevine varieties is essential information to adapt plant material in a changing climate

Precocity for fruit ripening is a genetically determined characteristic that is highly variable from one cultivar to another. In traditional wine-growing regions of Europe, growers have used this property to adapt the vines to local climatic conditions in order to maximize terroir expression

Oenological potential of cv. Tortojona: A minority grape variety from Extremadura, southwest Spain

This work, included in the VAVEGEX project, aims to evaluate the oenological, phenolic, chromatic and sensory characteristics of the grapes, must and wines produced from cv. Tortojona, minority variety grown in Extremadura region (Southwest, Spain).

The use of Hanseniaspora vineae on the production of base sparkling wine

Non-Saccharomyces yeasts have been associated, for many years, with challenging alcoholic fermentation processes. However, during the last decade the use of non-Saccharomyces yeasts in wine production has become increasingly widespread due to the advantages they can offer in mixed inoculations with Saccharomyces cerevisiae (Sc). In this respect, Hanseniaspora vineae (Hv), in synergy with Saccharomyces spp, represents an interesting opportunity to impart a positive contribution to the aroma complexity of wines. In fact, it is a well-known producer of pleasant esters, such as 2-phenylethyl acetate. This study compares the performances of Hv (strain Hv-205) in sequential inoculation modality to Sc in three Chardonnay musts for base sparkling wine production. No significant differences were observed in basic chemical parameters between wines except for titratable acidity, with a significantly decrease (up to 1.5 g/L) in Hv processes due to malic acid degradation. The analysis of the aroma compounds revealed remarkable differences in concentration of volatile metabolites, among others up to 37-fold increase of 2-phenylethyl acetate. In contrast, lower concentration of its alcohol were detected, suggesting higher acetylation activity by Hv.

Selective and sensitive quantification of wine biogenic amines using a dispersive solid-phase extraction clean-up/concentration method

Biogenic amines exist in numerous foods, including wine. They can have aliphatic (putrescine, cadaverine, spermine, and spermidine), aromatic (tyramine and phenylethylamine) and heterocyclic structure (histamine and tryptamine)

Natural sparkling wine pétillant naturel: technological features and sensory profile

The article presents the results of a study on the technological features of producing sparkling wines of the Pétillant Naturel (Pet-Nat) type, made using the ancestral method from the Muscat Ottonel and Pinot Noir grape varieties.
