The biomolecular characterization of foods and beverages represent nowadays an intriguing task for the scientific community. While nonvolatile compounds of a wine, e.g. polysaccharides, organic acids, mineral salts and polyphenols, have a great impact on the mouthfeel with acidity and salinity perceptions and astringency, the volatile component is the main responsible of wine aroma that contributes to the peculiar recognizability of a vine. Food aroma is the result of the complex interaction of small volatile molecules and odor receptors and, although its perception might be affected by subjectivity, it is considered as the first step in quality assessment.

Mapping the evolution of Chenin Blanc and Sauvignon Blanc wines
The post of this week tries to answer the question if different wines could change in a similar manner when placed in similar conditions, regardless of the initial composition. The chemistry of the wines, related to factors such as clonal differences, grape ripeness at harvest, terroir, and winemaking practices, was highly variable between the initial wines. The authors concluded that storage conditions had similar effects on all the wines included in the experiment, except for one Sauvignon Blanc and one Chenin Blanc wines, both from the same winery.
Enological repercussions of non-Saccharomyces species in wine biotechnology
