A zoning study of the viticultural territory of a cooperative winery in Valpolicella

Aging wine on lees is a consolidated practice during which some yeast components (e.g., polysaccharides, proteins, peptides) are released and solubilized in wine thus, affecting its stability and quality. Apart from the widely studied mannoproteins, the role of other yeast components in modulating wine characteristics is still scarce. Wine peptides have been studied for their contribution to taste, antioxidant, and antihypertensive potentials. However, the peptides detected in wine can be influenced by the interaction between yeasts and grape components.

Traditional agricultural and agro-pastoral systems (prior to industrial revolution) often have the characteristic of being multiple systems, in which multiple crops are hosted simultaneously on the same plot. currently research suggests to study more in depth the potential of multiple agricultural systems in order to detect those characteristics of multiple agrarian systems that could allow modern viticulture to adapt to the challenges posed by climate change: rising temperatures with impacts on the phenological cycle of the vine, resurgence of plant deseases, extreme soil washout phenomena and hail storms, among others.

Wine is an intrinsically complex aromatic product. To formalize this aromatic diversity and the hierarchical structure of the aromas, it is common to present them in the form of a wheel of aromas. These are used for learning and communication purposes but never for the acquisition of sensory characteristics.

This study examines the growing season climates of selected wine regions worldwide that have significant areas under Pinot noir.

Œnococcus oeni is a wine-associated lactic acid bacterium performs the malolactic fermentation, which improves the taste and aromatic complexity of many wine.
