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.

<p style="text-align: justify;"><strong>Aims</strong>: The effects of cluster thinning on yield and extractability parameters of Syrah and Tempranillo grapes, as well as the chromatic characteristics of the wines obtained in three consecutive seasons.</p><p style="text-align: justify;"><strong>Methods and results</strong>: Grapes of Vitis vinifera L. var. Tempranillo and Syrah were harvested from a commercial vineyard in Jumilla. Two treatments were evaluated: (a) cluster thinned, where in every shoot all the clusters, except the basal one, were removed just before veraison; (b) unthinned control. Yield, physicochemical and extractability parameters were studied in the grapes. Vinifications were made from these grapes, and chromatic parameters were studied at the end of alcoholic fermentation. Results showed that cluster-thinned vines performed better than control vines during the three consecutive years of the experiment, although the best results were obtained in the driest year (2005). The Syrah variety always provided better results than the Tempranillo variety. The cluster-thinning treatment also influenced the chromatic characteristics of the wines obtained.</p><p style="text-align: justify;"><strong>Conclusions</strong>: The results showed that thinning successfully reduced yield and produced an earlier harvest in the two varieties studied. The grape quality improved and, in general, wines made from cluster-thinned vines of both Syrah and Tempranillo had significantly better chromatic characteristics than control wines.</p><p style="text-align: justify;"><strong>Significance and impact of the study</strong>: This study demonstrate that the practice of cluster-thinning may be recommended depending on several factors, as the varieties and the climatic conditions play also a role in the extractability parameters of grapes, and therefore its use cannot be generalized.</p>
