“…The potassium (K) was quantified between 1.00 and 2.06 g/L (median of 1.39 g/L), whereas the YAN (yeast assimilable nitrogen taken as the sum of NH 4 + , free α-amino acids and some small peptides) was between the limit of quantitation (<20) and 163 mg/L (median of 83 g/L). Based on the scientific literature, the above parameters fall into the technological variability characteristics of Moscato grape varieties, regardless of cultivation site, production year and climatic conditions [20,26,27].…”

Among the Moscato grapes, Moscato Giallo is a winegrape variety characterised by a high content of free and glycosylated monoterpenoids, which gives wines very intense notes of ripe fruit and flowers. The aromatic bouquet of Moscato Giallo is strongly influenced by the high concentration of linalool, geraniol, linalool oxides, limonene, α-terpineol, citronellol, hotrienol, diendiols, trans/cis-8-hydroxy linalool, geranic acid and myrcene, that give citrus, rose, and peach notes. Except for quali-quantitative analysis, no investigations regarding the isotopic values of the target volatile compounds in grapes and wines are documented in the literature. Nevertheless, the analysis of the stable isotope ratio represents a modern and powerful tool used by the laboratories responsible for official consumer protection, for food quality and genuineness assessment. To this aim, the aromatic compounds extracted from grapes and wine were analysed both by GC-MS/MS, to define the aroma profiles, and by GC-C/Py-IRMS, for a preliminary isotope compound-specific investigation. Seventeen samples of Moscato Giallo grapes were collected during the harvest season in 2021 from two Italian regions renowned for the cultivation of this aromatic variety, Trentino Alto Adige and Veneto, and the corresponding wines were produced at micro-winery scale. The GC-MS/MS analysis confirmed the presence of the typical terpenoids both in glycosylated and free forms, responsible for the characteristic aroma of the Moscato Giallo variety, while the compound-specific isotope ratio analysis allowed us to determine the carbon (δ13C) and hydrogen (δ2H) isotopic signatures of the major volatile compounds for the first time.

“…Wine-growing areas where vineyards are located on steep slopes have been proven to be more functional to customizing the style of wine according to those trends. Potisek et al (2023) [130]'s calculations of the GDD index for the growing season period in western Slovenia (SI) during the 2015 and 2017 vintages have resulted in values <2000 units, as demonstrated in Figure 3 for P3. Similarly, calculations conducted by Šuklje et al (2022) [131] for Litmerk (northeastern Slovenia) resulted in GDDs of 1674, 1876, and 1553 for the 2017, 2018, and 2019 vintages, respectively, thus exhibiting values below the threshold of 2000 thermal units, as in Figure 3.…”

The agricultural sector faces significant challenges worldwide due to climate change. The pressure exerted by altered thermal conditions drives the zonal shift for various cultivations. This study aims to analyze and present the spatiotemporal evolution of the growing degree days (GDD) index in the northern Mediterranean Basin (NMB). More specifically, this research presents the multiyear analysis of the GDD index, which is focused on a high-value vine cultivation derived from the E-OBS dataset. The investigated time period spans from 1969 to 2018, and the performed analysis indicates a broad shift/expansion in areas with GDDs exceeding 2000 heat units. This is present in traditional winemaker countries such as France and Italy. Still, it is also evident that there is a high positive change in countries such as Serbia, Bulgaria, and other Balkans countries. The findings may be helpful in the strategic planning of the agricultural sector in these countries or on a vinery scale.
