Come proteggere un territorio viticolo: il punto di vista del giurista

Controlling the development of the bacterial population during the winemaking process is essential for obtaining correct wines[1]. Carbonic Maceration (CM) wines are recognised as high-quality young wines. However, due to its particularities, CM winemaking implies a higher risk of bacterial growth: lower SO2 levels, enrichment of the must in nutrients, oxygen trapped between the clusters… Therefore, wines produced by CM have slightly higher volatile acidity values than those produced by the destemming/crushing method[2].

Les paysages participent à l’identité des vins de l’Hérault, avec une grande richesse de diversité. Leur observation, au travers des quatre saisons, s’appuie sur deux dimensions primordiales : la genèse de leur construction par l’homme et l’esthétique. L’hiver est la saison la plus favorable au décryptage de ce vignoble étagé, du littoral méditerranéen aux premières pentes du Massif Central; il permet de lire l’histoire des stratégies viticoles des vignerons. Les autres saisons sensibilisent plus à la beauté de vignobles dans des écrins de végétation typiquement méditerranéenne. La multiplicité des pratiques culturales et des cépages contribue à cet attrait. L’incitation au parcours, en toute saison, est très forte grâce au réseau des routes et des chemins de vigne.

Understanding the composition of wine and how it is influenced by climate or wine-making practices is a challenging issue. Two approaches are typically used to explore this issue. The first approach uses chemical
fingerprints, which require advanced tools such as high-resolution mass spectrometry and multidimensional chromatography. The second approach is the targeted method, which relies on the widely available 1-D GC/MS, but involves integrating the areas under a few peaks which ends up using only a small fraction of the chromatogram.

La Franciacorta è una piccola regione collinare della provincia di Brescia. Il territorio è molto eterogeneo sia dal punto di vista geologico, che geomorfologico e pedologico. Circa 1.000 ettari sono destinati alla produzione di uve Chardonnay, Pinot bianco e Pinot nero per il vino Franciacorta ottenuto unicamente utilizzando la lunga fermentazione naturale in bottiglia.

In vineyard management, the block is considered today as the technical work unit. However, considerable variability can exist inside a block with regard to physiological parameters, such as vigour, particularly because of soil heterogeneity. To represent this variability spatially, many measurements have to be taken, which is costly in both time and money. High resolution remote sensing appears to be an efficient tool for mapping intra-block heterogeneity.
