“…Therefore, this variation is ascribed to the effects of climate, nutritional and water status of the plant and grape ripening status at harvest time (Reynolds and Vanden Heuvel, 2009). The skin polyphenols contents observed for 'Sauvignon Blanc' were similar to those obtained by Brighenti et al (2014) in white varieties like 'Vermentino', 'Verdicchio' and 'Prosecco' grown at altitude, and are higher than those found by Wurz et al (2018) in the 'Sauvignon Blanc' variety grown at altitude. Similar results were observed by Bavougian et al (2012), who did not verify the effect of training system on the accumulation of total polyphenols in grape berries.…”

The objective of the present work was to compare the effect of the training systems Y-trellis (Y) and Vertical Shoot Position trellis (VSP) on the production efficiency and chemical characteristics of grapes and wine from ‘Sauvignon Blanc’ cultivated in high altitude regions of Santa Catarina State, Brazil. The study was carried out in 2013, 2014 and 2015 harvests in a commercial vineyard located in the municipality of São Joaquim - SC (28º 17 ’38 ”S and 49º 55’54” O, altitude 1350 m). The obtained data were subjected to analysis of variance (ANOVA) with F Test (p ≤ 0.05). The relationship between the vegetative growth and the yield was influenced by the training system. For the ‘Sauvignon Blanc’ cultivar, the yield was 93% higher in the Y-trellis training system, resulting in better vegetative-productive balance. The technological and phenolic maturation of the grapes were similar in both training systems. The results of this study show that the Y-trellis training system is an alternative to use in Santa Catarina altitude regions because it provides an increased productivity on the ‘Sauvignon Blanc’ variety without compromising the composition of grapes, when comparing to the VSP training system.

“…The lowest productivity was from Aromera produced at 1100 m. Productivity is one of the most important parameters to be considered in variety selection, mainly in white varieties, that does not need to reach high levels of soluble solids and need to maintain the acidity for elaboration of white wines and sparkling wines [17]. These values are much higher than those found in Brazil in vines trained in VSP [18][19][20], which shows the differentiated productive potential of Felicia and Calardis Blanc. In the same way, Aromera also presents satisfactory productivities.…”

“…Felicia produced at 830 m is the most fertile and the most heavily cluster. In previous works the values of fertility index were on average 0.85 for different Italian varieties, 1.00 for Cabernet Sauvignon and 1.12 for Sauvignon Blanc grown in highlands of Santa Catarina State [18][19][20].…”

In southern Brazil there is a predominance of labrusca and hybrid varieties for wine and juice production due to climatic conditions of high rainfall, temperature and relative humidity. Growing varieties that combine disease resistance and wine quality (PIWI) can be an alternative to improve wine quality. The objective of this work was to evaluate the performance of three PIWI varieties (Felicia, Calardis Blanc and Aromera) in two regions (Videira, 27 • 01"S and 51 • 08"W, altitude 830 m; and São Joaquim, 28 • 13"S and 50 • 04"W, altitude 1100 m) in the vintage 2018. The date of occurrence of main phenological stages, productiveindexes, clusters characteristics and grape qualitative indexes was evaluated. There was no difference for budbreak date, but flowering, veraison an maturity time varied between regions. The development of plants is slower when they are cultivated at a higher altitude. The number of clusters per plant and yield were higher at 830 m for all varieties. For productive indexes Felicia and Calardis Blanc varieties stood out in relation to Aromera in all parameters. Among the evaluated varieties, Felicia and Calardis Blanc were better adapted to the lower altitude region and had higher productivity and the same grape quality. On the other hand, Aromera presented higher productivity at 830 m but higher soluble solids content at 1100 m.

“…In the last decade, the highlands of the state of Santa Catarina, in Southern Brazil, have stood out as a region for the production of high-quality wines (Würz et al, 2018). Of the white varieties, the Sauvignon Blanc grapevine (Vitis vinifera L.) cultivar is the most important and can be considered well adapted to the edaphoclimatic conditions of the region due to its late bud break and to its early/intermediate maturity (Brighenti et al, 2013).…”

These characteristics, associated with specific terroir factors, allow the production of white wines with intense aroma, complexity, and typicity (Würz et al, 2018(Würz et al, , 2020a.…”

The objective of this work was to evaluate the effect of different techniques to modify grape cluster architecture on the incidence and severity of botrytis bunch rot, as well as on the viticultural performance of the 'Sauvignon Blanc' grapevine (Vitis vinifera). Associated with fungicides, four treatments were tested: control, 30 ppm gibberellic acid sprayed at full bloom, 1,000 ppm prohexadione calcium sprayed at full bloom, and berry thinning at the stage of beginning of berry touch. The experiment was carried out in the 2015, 2016, and 2017 vintages. Clusters were treated with fungicides during the stages of full bloom, beginning of berry touch, veraison, and around 15 days before harvest. Berry thinning does not cause losses in the yield and quality of 'Sauvignon Blanc', and, despite having little effect on cluster architecture, is effective in reducing the incidence and severity of Botrytis cinerea. Prohexadione calcium improves grape phenolic maturation, is effective in reducing the incidence and severity of B. cinerea, and reduces cluster compactness by decreasing berry diameter. The application of gibberellic acid spray at full bloom is not recommended because it decreases yield and bud fertility and increases berry susceptibility to B. cinerea infection.
