Differentiating and grouping of oltrepo’ pavese environments according to grape maturation

Wine quality is a complex concept determined by multiple factors, including vineyard management, winemaking operations, and the sensory perception of key attributes.

The objective of this work is to study the vulnerability of vineyard soil to compaction.

The research carried out by the URVV of the INRA center in Angers aims to develop a methodology for the integrated characterization of the natural factors of viticultural terroirs, representative of the operating conditions of the vine and the sensory differences of the wines. In this context, the concept of Basic Terroir Unit (UTB) has been developed. The UTB represents a viticultural surface of variable geographical extension, defined as the association in a given place of a geological, pedological and landscape component, Morlat (1989), Riou et al. (1995).

Albariño is a white cultivar that has been recently promoted in Uruguay due to its ability to maintain high berry quality even in adverse climate conditions during ripening. This study aims to assess the effect of different topographic conditions on Albariño agronomic behavior and oenological potential.

The management of yeast nutrition is an essential approach for a better control over wine fermentation process. Most of the researches on this subject in the last decades focused on nitrogen nutrition. However, vitamins, while being key compounds for yeast metabolism as co-factors for numerous enzymatic activities, were left mostly unexplored.
