“…The concentration of these compounds in different parts of plants may vary, and stress factors, to which plants are exposed, may change their contents in grape berries [5]. Although the phenolic profiles of grapes depend on various factors, such as cultivar, maturity [6], genetic diversity [7], viticulture practices [8], soil characteristics [9], environmental stress and vine health status [9], the composition of phenolic compounds in grape berries strongly depends on cultivars [10][11][12]. The distribution of phenolic compounds in grape berries seems irregular.…”

The main purpose of this study is to determine the contents of 3 major phenolic compounds (gallic acid, catechin, and epicatechin) in 22 different grape cultivars/hybrids obtained from 2 different breeding programs. Additionally, changes in these phenolic components in the grape leaves of some resistant/tolerant species were determined in relation to powdery and downy mildew diseases in viticulture. The skin, pulp, and seeds of grape berries were analysed over two years, while changes in the phenolic contents of grape leaves were determined before and after these diseases for two years. The major phenolic contents of new hybrids/cultivars were compared with those of popular cultivars in different parts of the grapes, and significant differences in phenolic contents were found among hybrids/cultivars and different grape parts. Variations in the contents of phenolics in grape seeds, skins, and pulp were high, but seeds contained higher levels of these phenolics than pulp and skin. Analyses of the relationship between two viticultural diseases and phenolic changes in resistant/tolerant cultivars in relation with the susceptible “Italia” cultivar revealed that an increase in the content of the phenolic compounds was found after powdery mildew disease. Hybrids/cultivars with high phenolic contents are recommended to develop new superior cultivars, which are resistant to grape fungal diseases, in breeding programs.

“…In addition, different factors can affect the phenol composition, such as climatic conditions, seasonal variations of weather, soil conditions, agronomical practices, etc. [ 37 , 38 ]. Our previous research was conducted on grapes harvested in the 2017 season, and some samples were of the same varieties [ 39 ].…”

“…Total phenolic content of extracts fluctuated remarkably. Such data distribution can be explained by different factors such as: climate conditions and seasonal variations, soil characteristics, varietal characteristics, environmental conditions, agronomical practices, sample management, and so on [ 37 , 38 , 48 ]. Herein, some of the factors can be excluded.…”

Winemaking generates large quantities of grape waste consisting of seeds, skin and stalks. Given that grape seeds are a rich source of different bioactive compounds, the main goal of this research was to optimize grape seed phenol extraction using a Box–Behnken design. The following conditions were derived from the optimization process: sample:solvent ratio of 1:10 w/v, extraction time of 30 min and extraction temperature of 50 °C. In addition, a sustainable (green) approach for obtaining extracts was developed by comparing choline chloride:citric acid-ChCit (natural deep eutectic solvent (NADES)) and ethanol extraction methods with respect to phenol profiles and antioxidant activity. This study was conducted on seeds from eight different red grape varieties. Phenolic acids, flavan-3-ols and procyanidins were characterized using HPLC–MS/MS, and the concentration of procyanidin B1 was above 1 mg/g of dry weight in all analyzed samples. The contents of all phenol classes and antioxidant activities were found to not differ significantly between the solvents, but NADES was found to offer valuable advantages. Importantly, ChCit showed a strong affinity toward procyanidins and a strong correlation between antioxidant activity and quantified phenolic compounds.

“…In last years, several studies were carried out to analyze the adaptability of the different V. vinifera varieties in the different Chinese wine regions under diverse climatic and soil conditions combined with several agronomic practices. The results show a good adaptability for most of the cultivars maintaining all its specific potentialities but affected by the environmental conditions [81,82].…”

Recent Advances in Grapes and Wine Production - New Perspectives for Quality Improvement

View full text Add to dashboard Cite

In the last two decades, several international grape varieties from different traditional wine countries such as, France, Portugal, Italy, and Spain have been introduced in several world wine regions, increasing their representation in the world. The introduction of grape varieties in emerging regions with diverse environmental conditions from their natural origin introduces challenges on the adaptability of these varieties in new specific “terroirs,” not only in terms of their productivity but also related with the grape and wine characteristics. In addition, it is also important to compare their characteristics with native grape varieties grown in the local regions. On the other hand, climate change has also promoted greater mobility of grapes to new regions, increasing the dispersion of various grape varieties in areas where viticulture was, until now, severely limited. Thus, considering the importance of the dispersion of several grape varieties in regions out of the original provenance, the purpose of this chapter is to present a review of the most recently published data about the adaptation of several grape varieties in different environments and the impact on their qualitative characteristics (including in wines produced). The comparative analysis with some of the native varieties existing in these environments, when applicable, will also be analyzed.
