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. Optimization of extraction time and temperature for natural antioxidants of öküzgözü grape pomace using various solvent ratios
Abstract Grape pomace, a press residue of winemaking process, has great usage potential in many fields because of its phenolic components such as anthocyanins, antioxidants and dietary fiber. In this study, it was aimed to determine most suitable parameters for production of food colorant from grape pomace (variety of öküzgözü) under different extraction

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. 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

5. Maturation and Maceration Effects on Tropical Red Wines Assessed by Chromatography and Analysis of Variance - Principal Component Analysis
Effects of grape maturity, maceration length during winemaking and interaction of both of them on physicochemical parameters, phenolic and volatile composition were investigated in tropical Syrah wines with the aim of finding the best conditions to produce wines that are rich in phenols and positive aroma active compounds. A headspace solid phase micro extra

6. Evaluation of the potential astringency of the skins and seeds of different grape varieties based on polyphenol/protein binding
Abstract The potential astringency of eight grape cultivars was evaluated based on polyphenol/protein binding. The parameters such as weights, sizes, total phenols, flavanols and tannins of different grape tissues were determined, and the polyphenol/protein binding was analyzed by SDS-PAGE and spectroscopy. The Cabernet Sauvignon had the highest skin proport

7. Process optimization, physicochemical characterization and antioxidant potential of novel wine from an underutilized fruit Carissa spinarum L. (Apocynaceae)
Abstract Carissa spinarum L., is a tropical underutilized fruit abundantly available during summer season, which is delicious to taste with an astringency flavor and fruity aroma. Hence, the present investigation was aimed at optimizing fermentation conditions for the production of wine and to assess its physiochemical composition and antioxidant activity. R

8. Chemical composition of cold pressed Brazilian grape seed oil
Abstract Grape seed oil (GSO) is an important by-product of the wine-making industry which has received attention as an alternative source of vegetable oils; its chemical compounds can be influenced by agricultural practices and industrial processing. Knowledge of the composition of Brazilian GSO is scarce; thus, this study aimed to analyze the chemical char

9. Impact of Fungicide Residues on Polymerase Chain Reaction and on Yeast Metabolism
ABSTRACT The indiscriminate use of pesticides on grape crops is harmful for consumers´ healthin “in natura” consumption and in the ingestion of wine and grape juice. During winemaking, a rapid and efficient fermentation stage is critical to avoid proliferation of contaminating microorganisms and to guarantee the product´s quality. Polymerase chain reac

10. Characterization of pectinase activity for enology from yeasts occurring in Argentine Bonarda grape
Pectinolytic enzymes are greatly important in winemaking due to their ability to degrade pectic polymers from grape, contributing to enhance process efficiency and wine quality. This study aimed to analyze the occurrence of pectinolytic yeasts during spontaneous fermentation of Argentine Bonarda grape, to select yeasts that produce extracellular pectinase

11. Effects of orange winemaking variables on antioxidant activity and bioactive compounds
AbstractAscorbic acid, carotenoids and polyphenols stand out among the orange juice natural antioxidants. The winemaking process affects their bioavailability and bioactivity. Antioxidant activities (AA) were estimated in different process conditions to asses those properties. The AA and their correlation with ascorbic acid, total phenolics and carotenoids c

12. Análise multiparamétrica da qualidade dos frutos, mostos e vinhos de jabuticaba / Multiparametric analysis of quality of fruits, musts and wines jabuticaba
Chemical parameters were monitored during the jabuticabas development, fermentation and ageing of its wine, by quantitative 1H NMR, spectrophotometric assays and standard methods of analysis. Data collected were analysed by variance (ANOVA), principal components (PCA), hierarchical cluster (HCA) and canonical correlation analyses (CCA). Jabuticabas developme
