“…As an example, in the La Rioja wine region, the cool suitability class (HI-2) shifted from 716.7 m asl in the past to 922.9 m asl between 1991 and 2010, while a new suitability class appeared in the lowland, respectively, the warm class (HI+2). This result is in perfect agreement with similar developments expected for Serbia [72], Austria [73], Hungary [74], Romania [52], Germany [75], or for the high-altitude regions of northwestern Spain [26,76]. For lowland wine regions, such as Sussex (57 m asl), with no available altitude for climate class expansion or shift, the old suitability class or classes are only gradually replaced by new, increasingly warm suitability classes generated by rising temperatures due to climate change.…”

“…Our research shows that climate change causes significant spatial shifts in the viticulture potential in wine-growing regions, a fact expected or demonstrated by numerous previous research papers [24,25,28,52,54]. Along with these spatial shifts, in the wine regions, there is the need to relocate the traditional varieties on the sites with their corresponding viticulture potential in order to adapt the local viticulture to the new conditions of climate suitability by introducing new varieties [68] and, implicitly, technological adaptation, through decisions such as changing vine management systems or using new rootstocks [69].…”

“…These differences are represented by the appearance in the wine regions during the 1991-2010 time period of new classes of climate suitability, which radically changed the structure and weight of the types of wine production specific to the 1951-1990 time period. Such shifts of suitability classes have been highlighted and described at large in our previous research [28,29,52].…”

Climate change modifies the base climate of the wine regions and, with it, the structure of their traditional types of wine production, imposing measures to adapt, mitigate, or capitalize on the newly emerging conditions. In order to assess the impact of climate change and establish the appropriate adaptation measures for each wine region, regional and local studies are needed, which allow knowledge of their current climate profile. The aim of this research was to identify the changes that appeared as an effect of climate change in the initial climate profile and the initial structure of the traditional types of wine production of Bordeaux (France), Loire Valley (France), Rhine-Main-Nahe (Germany), La Rioja (Spain) and Cotnari (Romania) wine regions, and also in climate suitability for wine production of the Sussex area from the UK. The study uses multi-year averages for the 1951–1990 and 1991–2010 time periods of reference bioclimatic indices for viticulture, namely the Average Temperature of the Growing Season (AvGST), the Huglin Index (HI), and the Oenoclimatic Aptitude Index (IAOe). The results of this research reveal significant changes in climate suitability for wine production of the studied wine regions: in the Bordeaux wine region, climate change led to the appearance of conditions for the cultivation of the Mediterranean climate varieties Grenache, Syrah, and Carignan; in the cool climate wine regions Rhine-Main-Nahe and Cotnari, traditional producers of white wines, the climate has also become suitable for the cultivation of Pinot noir and Cabernet franc varieties, and implicitly for the production of red wines; in all studied wine regions, the classes of climate suitability for viticulture shifted higher in altitude, as is the case of the La Rioja region, where, in the recent period, the grapevine can be grown up to 922.9 m asl, higher by 206.2 m compared to the 1951–1990 time period; in the low area of each wine region, one or even two new climate suitability classes for wine grape growing appeared. The shifts revealed by this research generate solid conclusions regarding the effect of climatic change on the viticultural potential of geographical areas, namely: in the context of climate change, the altitude of the wine region has a major influence on the evolution of the local viticulture potential; a higher topography allows a better adaptation of the wine region to climate change; low-elevation wine regions are more vulnerable to climate changes, especially the further south they are located; as an effect of climate change, conditions appear in the wine regions for the cultivation of new grapevine varieties and the production of new types of wine.

“…These studies revealed the effects of climate warming on the evolution of phenological stages [8], on grapevine growth and developement, on grape yield and quality. Studies have also been conducted to recommend adaptation of viticultural practices to climate change [9], as well as for the re-assessment of climate suitability for the wine production of Romanian wine growing regions [10,11]. In various vineyards of the world, important researches have been carried out on the effects of climate change and the adaptation of viticulture to the new conditions [12][13][14][15][16].…”

The climate change influences and trends on the grapevine growing in Southern Romania: A long-term study

The topography and pedoclimatic conditions in Romania are diverse and in many places highly favourable for viticulture. In the past 21 years it was observed that the climate slowly changed, with a visible impact on grape quality. The influence of climate change on grape growing depends however on the vineyard location, relief and soil, multiple combination of varieties and rootstocks, water supply, as well as viticultural practices. The influence of the climate change was studied during a long period of time, between 1998 and 2018, in our experimental vineyard at UASVM Bucharest (N Lat.: 44∘47′07′′; E Long.: 26∘076′28′′; elevation 87 m), located in the Southern part of Romania. The observations made during last twenty one years on qualitative and quantitative parameters of the most widespread Romanian grape variety, Fetească regală grafted on the Kober 5 BB rootstock, along with the calculated values for the usual climatic indices describing viticultural climate, showed some significant climate changes in comparison with a reference period between 1961 and 1997 taken from the existent scientific literature. Our observations during past twenty years reveal a trend of increase in all studied temperature-dependent climatic indices during the grape growing season, with a large variation in the absolute minimum temperatures during winter, which suggests a shift towards an increased thermal amplitude between summer and winter temperatures in certain years. Compared with the reference period (1961–1997), an increase in the following temperature-dependent indices was observed: +0.75 ∘C for the average annual temperature; +0.78 ∘C for average temperature in the growing season; +2.37 ∘C for average maximum temperature in the warmest month; +2.11 ∘C for average maximum temperature in the summer; +234 units in Huglin index; + 173 units in Winkler index and +0.35 ∘C in Cool night index. These climate changes bring important variations of grape yield due to the minimum temperatures during winter and significant reduction of total acidity, along with a significant increase of sugar concentration. This study aids to understand and anticipate the rate of climate change in Southern Romania, the extent of the changes in grape quality and the interventions required to maintain constant grape and wine quality.

“…The lees are the residue accumulated after the fermentation of the wine consisting predominantly of yeasts and impurities originating from grapes. Two main fractions comprise lees by-products [ 8 ]: a combination of proteins, insoluble carbohydrates, organic acids, yeasts, inorganic salts, and phenolic molecules provides the solid fraction [ 9 ], while ethanol, acetic acid, and lactic acid are the main compounds of the liquid fraction [ 10 ]. Environmental conditions, grape variety, and regions of origin are agronomic parameters that deeply influence the chemical composition of lees [ 11 ].…”

Wine Lees as Source of Antioxidant Molecules: Green Extraction Procedure and Biological Activity

et al. 2023

An ultrasound-assisted extraction method, employing ethanol and water as solvents at low temperature (30 °C) and reduced time (15 min), was proposed to extract bioactive molecules from different cultivars (Magliocco Canino, Magliocco Rosato, Gaglioppo, and Nocera Rosso) of wine lees. All the extract yields were evaluated and their contents of phenolic acids, flavonoids, and total polyphenols were determined by means of colorimetric assays and high-performance liquid chromatography coupled with diode-array detection (HPLC-DAD) and Fourier transform infrared (FTIR) techniques. Radical scavenging assays were performed and the Magliocco Canino extracted with a hydroalcoholic mixture returned the best results both against ABTS (0.451 mg mL−1) and DPPH (0.395 mg mL−1) radicals. The chemometric algorithms principal component analysis (PCA) and partial least square regression (PLS) were used to process the data obtained from all qualitative–quantitative sample determinations with the aim of highlighting data patterns and finding possible correlations between composition and antioxidant features of the different wine lees cultivars and the extraction procedures. Wine lees from Magliocco Canino and Magliocco Rosato were found to be the best vegetable matrices in terms of metabolite content and antioxidant properties. The components extracted with alcoholic or hydroalcoholic solvents, specifically (−)-epigallocatechin gallate, chlorogenic acid, and trans-caftaric acid, were found to be correlated with the antioxidant capacity of the extracts. Multivariate data processing was able to identify the compounds related to the antioxidant features. Two PLS models were optimized by using their concentration levels to predict the IC50 values of the extracts in terms of DPPH and ABTS with high values of correlation coefficient R2, 0.932 and 0.824, respectively, and a prediction error lower than 0.07. Finally, cellular (SH-SY5Y cells) antioxidant assays were performed on the best extract (the hydroalcoholic extract of Magliocco Canino cv) to confirm its biological performance against radical species. All these recorded data strongly outline the aptness of valorizing wine lees as a valuable source of antioxidants.
