Understanding the expression of gene families involved in anthocyanin biosynthesis during berry ripening: Tannat as a case study

Multi-mineral wine profiling and artificial intelligence: implementing the signatures of each wine to train algorithms to meet the new challenges facing the wine industry. Although their quantity is minimal, minerals are essential elements in the composition of every wine. Their presence is the result of complex interactions between factors such as soil, vines, climate, topography, and viticultural practices, all influenced by the terroir. Each stage of the winemaking process also contributes to shaping the unique mineral and taste profile of each wine, giving each cuvée its distinctive characteristics.

‐Evaluation of xylem embolism is an important challenge in identifying drought tolerant genotypes within the context of climate change.

Irrigation management is a critical aspect in grapevine cultivation to regularize grape production and quality in areas of clear water limitation.

Although the ripening process of grapevine berries is well-documented at the vineyard level, pinpointing distinct developmental stages remains challenging. The asynchronous development of berries results in dynamic biases and metabolic chimerism. It is thus crucial to consider individual berries separately and resynchronize their internal clock for deciphering physiological changes throughout development. Given the importance of grape composition in wine quality, we aimed at measuring developmental changes in the metabolome of Syrah single berries from anthesis to over-ripening, without a priori preconceived.

 Temperatures are increasing due to climate change leading to advances in grapevine phenology and sugar accumulation in grape berries.
