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.

La diffusion récente et “explosive” du Chardonnay dans pratiquement toutes les zones de culture viticole du monde a fait penser, à tort, que cette variété s’adapte facilement à toutes les conditions pédo-climatiques ou presque. Cette thèse a été confirmée par la grande faculté d’adaptation dont a fait preuve le vignoble et par la popularité dont jouit le vin auprès des consommateur du monde entier.

Influence du terroir sur la composition en flavonoïdes de la baie de raisin de Cabernet franc en Moyenne Vallée de la Loire

The terroir offers great variability in the typicity of the wines produced. Following tastings integrating several vintages, the multiple factor analysis of the sensory data revealed a group of taste criteria contributing to the notion of “Power”, referenced “Power and Harmony”, which makes it possible to differentiate wines from various terroirs of the Middle Loire Valley (Pages et al ., 1987).
