1. Wine composition of Merlot and Cabernet Sauvignon vine clones under the environmental conditions of Serra Gaúcha, Brazil
Abstract This study aimed to evaluate the wine composition from vine clones of Merlot (181, 346, 347, 348) and Cabernet Sauvignon (R5, 18A, 163, 338, 341). The grapes were harvested between 2010 and 2012, then on the same day, taken to the winery facility for winemaking. After crushing and destemming the grapes, the musts were transferred to glass containers

2. Difference and characteristics of anthocyanin from Cabernet Sauvignon and Merlot cultivated at five regions in Xinjiang
Abstract Anthocyanin plays an important role in wine color and quality. The anthocyanin concentration in grapes depends on the variety and is influenced by environmental factors, such as temperature, sunlight, soil, and grapevine practice. In this study, the anthocyanin profiles of two varieties, namely Cabernet Sauvignon and Merlot, from five regions (11 pl

3. Production of functional products using grape processing residuals
Abstract The viticulture – winemaking of Azerbaijan has a rich history and traditions. Grapes have been cultivated and wine made in these places since the ancient times. In the 1980s, the field was in a boom period and provided economic benefits at a level comparable to the country's oil industry revenues. Although the area is currently experiencing a rece

4. Late defoliation of ‘Chardonnay’ grapevine in subtropical highland climate
ABSTRACT Chardonnay cultivar has shown great potential of planting and development in sites above 900m of Brazilian southeast for sparkling wines production. The quality of this product is related to vineyard climate and management, since both affect the vine development and grape composition. In this study, three defoliation orientations (east, west and eas

5. Physicochemical Characterization, Antioxidant Potential and Sensory Quality of Wine from Wild Edible Fruits of Flacourtia montana J. Graham
Abstract The objective of the present study was to produce wine from wild edible fruits of Flacourtia montana J. Graham. The various physicochemical attributes including total phenolic content and total flavonoid content were analyzed. Further, the prepared wine was evaluated for the antioxidant potential using four different assays, viz., 2,2'-azino-bis(3-e

6. Viticultural performance of Cabernet Sauvignon clones in highland region of southern Brazil
Resumo A cultivar Cabernet Sauvignon é uma das videiras para vinho mais amplamente cultivada comercialmente no Brasil. Seu desempenho em relação à qualidade final da uva depende do clone, do porta-enxerto e do “terroir” onde os vinhedos estão localizados. Este estudo teve como objetivo avaliar e caracterizar os efeitos de sete combinações de clon

7. Defoliation, application of S-ABA and vegetal extracts on the quality of grape and wine Malbec cultivar
Resumo A alta taxa de chuvas e baixas temperaturas podem fazer com que as uvas não atinjam índices adequados de maturação. O objetivo deste trabalho foi avaliar a remoção de folhas, regulador hormonal e extratos vegetais na qualidade da uva e do vinho. Um experimento foi conduzido em um vinhedo com a cv. Malbec, no sul do Brasil, por duas safras conse

8. Canonical correlations among grapevine agronomic and processing characteristics
ABSTRACT. Canonical correlation analysis allows conclusions to be drawn about the occurrence and magnitude of associations between two groups of characteristics. This study estimated the magnitude of association and interdependence between two trait groups of clones of two varieties of Vitis vinifera grapes. The study was based on the mean data of eight char

11. Abscisic acid and ethephon treatments applied to ‘Verdejo’ white grapes affect the quality of wine in different ways
ABSTRACT: Exogenous ethephon and abscisic acid (ABA) treatments are used worldwide to improve the coloring of red table grapes, but there is little information about their impact on the quality of white grapes and wines. The aim of this work was to evaluate the effects of exogenous ethephon and ABA applications at veraison on the composition of ‘Verdejo’
