Abstract
The effects of climatic conditions and soil type on grape ripening and wine quality were studied for the period 2003–2005, in two Cabernet Sauvignon vineyards under the same climate but on very distinct soils. Climate effect was estimated by studying annual variations. Climatic conditions and soil had overall a significant effect on grape ripening. The effects of soil and climate could be explained mainly by their influence on plant water availability status. Soil type appeared to be determining wine phenolic composition, and related wine tasting characteristics.
