Chemical composition of red wines made from hybrid grape and common grape (Vitis vinifera L.) cultivars

The aim of this work was to investigate the effect of meteorological conditions on resveratrol concentration of red wines produced in Piacenza viticultural region (Italy). In this regard, six representative estates producing Colli Piacentini Gutturnio DOC (a blend of V. vinifera L. cvs. Barbera and Croatina) vintage wines were analysed for trans- and cis-resveratrol over an 8-year period (1998–2005). Grapes were taken from the same vineyard in each estate by using the same enological practices over the entire investigated period. The meteorological conditions corresponding to the production areas were recorded, and bioclimatic indices were calculated as well. Overall, cis-resveratrol concentration was negatively correlated to Huglin index and August mean temperature, whilst positive correlation coefficients were found when considering the Selianinov index and the rainfall of September.

The 19Th Century

The direction related with production of vine planting material originated from the 19th century, after the advent of Phylloxera vastatrix F. in which a large part of the vineyards in Bulgaria and the main wine-growing countries were destroyed. Only solution was proposed for grafting vine varieties from Vitis vinifera L. on resistant rootstocks. A number of biological characteristics of the vine influence both the nursery for scions and the rootstock nursery. One of them, which is main is the affinity of different rootstocks on the different vine varieties. In the southern Bulgaria, where the Mavrud variety is characteristic, high losses are observed due to the low yield of first-class vines. In Bulgaria, the Mavrud variety is highly valued due to its biological qualities, resulting in extracts and dense red wines that have glorified our country.
