Influence of some Terroir Viticole Factors on Quantity and Quality of Grapes
AbstractHigh wine quality can be only achieved with an appropriate vineyard management. However a lot of other factors will play also a decisive role: climate, soil, topography, micro-climate, human factors genetics, environmental and technological factors a.s.o.. Since years exists a discussion about the influence of the pedo-climatic system on wine quality. It can be summarized as terroir. The purpose of this study is to delimit some micro-areas in the Cotnari region which warrant the production of a certain type of wine, a quality. This is the first study attempting to characterize the terroir concept for Cotnari vineyards. It is applied on the behavior of traditional varieties of wine grapes grown in the region: Grasa de Cotnari, Feteasca alba, Francusa and Tamaioasa romaneasca. In a first run it was found out that the two Natural territorial base unit exert a distinct influence yield, sugar content and must acidity. This system has to be improved with further research in order to judge the vineyards in that region more precisely. The results of this study can be used to determine with precision micro-areas that will produce quality wines.
