A sensitive and simple method was developed for the classification of wines according to variety, geographical origin, and vintage using NMR-based metabonomics. Polyphenol-rich extracts were prepared from 67 varietal wines from the principal wine-producing regions of Greece, using adsorption resin XAD-4. 1D (1)H NMR spectra obtained from the corresponding extracts were segmented, integrated, and normalized, and the data were subjected to principal component analysis. The chemometric classification of wines according to their phenolic profile allows discrimination between wines from different wineries of the same wine-producing zone and between different vintages for wines of the same variety.

This research aims to identify aroma compounds, their combinations, and statistical relationships to classify and characterize wines produced in small, defined areas known as "terroirs", which share edaphoclimatic characteristics grape varieties, viticultural practices, harvest timing, and winemaking processes. The goal is to deepen the understanding of the relationship between the terroir and wine typicity. This study analyzed the contents based on enological parameters, the major and minor volatile compounds of the young wines produced in three wineries across two vintages, using the Pedro Ximenez white grape variety cultivated in different terroirs within the same quality zone.

To investigate the impact of genetic factors on wine aroma, wines made from 22 clones of five grape varieties ( L.) were used to analyze the volatile compounds by headspace solid phase microextraction gas chromatography mass spectrometer (HS-SPME-GC-MS) and headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS). Results showed that 52 and 49 aroma compounds were identified from 22 clones of wines by two technologies, respectively.

To diversify wine production in Xinjiang and address the issue of wine homogenization, it is crucial to leverage the unique climatic advantages of each grape-producing area to foster a high-quality wine industry. Using meteorological data from 80 national standard meteorological stations in Xinjiang, spanning 1961 to 2019, this study established a climatic zoning index system tailored to distinct grape varieties for wines, including dry red, dry white, ice wine, sparkling wine, and natural sweet wines. The system is formulated based on key climatic factors such as the frost-free period, ≥ 10 °C active accumulated temperature (AAT10), mean temperature of the coldest month, annual extreme minimum temperature, and dryness.

Background: Alcohol consumption frequently experiences episodes of severe anxiety. This study set out to explore the long-term effects of alcohol consumption on anxiety, revealing insights into how alcohol consumption uniquely impact anxiety, aiming to inform mental health and public health approaches. This research paper explores the complex relationship between the prevalence of anxiety and the consumption patterns of wine, beer, and spirits across fifty-two high-income countries with a continental analysis.

The relative performance of rhizobial strains could depend on their resource allocation, environmental conditions, and host genotype. Here, we used a high-throughput shoot phenotyping to investigate the effects of Mesorhizobium strain on the growth dynamics, nodulation and bacteroid traits with four chickpea (Cicer arietinum) varieties grown under different water regimes in an experiment including four nitrogen sources (two Mesorhizobium strains, and two uninoculated controls: nitrogen fertilised and unfertilised) under well-watered and drought conditions. We asked three questions.
