Soil survey and continuous classification for terroir delineation in the “Colli Orientali del Friuli” wine production area

Abstract

The combination of a non-parametric dissimilarity index with auger boring recordings was tested in a project of soil suitability evaluation for quality wine production in a 2000-ha hill slope portion of the “Colli Orientali del Friuli” AOC district (Italy). The morphological characteristics – horizon sequence and the characteristics of each horizon – of 236 auger borings were recorded in 2006 according to the conventional practice for detailed soil surveys. The combination of “soft” data recorded in the auger boring campaign and the unsupervised clustering procedure consistently reduced the costs of survey. In particular, it helped us to delineate three different soil-landscape units being candidate for terroir delineation. Viticulture trials now in progress will give a final answer at the end of 2008.

Sardinia terroir and Cannonau: a zoning approach to discover an ancient tradition

Cannonau variety is historically grown in a large Sardinia area (Jerzu district) and the vineyards are planted both in the plane and in the sloped hills reaching also 650 m of altitude a.s.l. Thus, in order to discover how climate, soil diversity and growing traditions could account for differences in grape and wine quality, this trial was carried out.

Future scenarios for viticultural climatic zoning in Europe

Climate is one of the main conditioning factors of winemaking. In this context, bioclimatic indices are a useful zoning tool, allowing the description of the suitability of a particular region

Landscapes of the wine: the four seasons of herault

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.
