Influence of Ecoclimatic and Ecopedological Conditions on Quality of White Wine Grape Varieties from North-West of Romania

Abstract

Viticulture is one of the cultures occupying large proportions of the cultivated area on the Globe. It is practiced, in particular, to produce table grapes, juice and other derivatives, and especially (about 70% of the total) to obtain different categories of quality wine and wine-based beverages. Wine can be produced everywhere, as long as the grapes ripen, but not all conditions for ripening the grapes are favorable for the production of quality wines (Teodorescu et al., 1987). If the area where vine is grown is large, the one objective is to evaluate the ecoclimatic and ecopedological conditions of three culture areas (Baia Mare (BM), Ažimleul Silvaniei (SS) and Turulung Vii (TUR)) in north-western Romania and their inIluence on the quality of the varieties: E»FeteascAƒ albAƒE¼, E»FeteascAƒ regalAƒE¼, E»Riesling italianE¼. The genetic soil types from these locations are: aluvosoil in Baia Mare, luvosoil in Ažimleul Silvaniei and preluvosoil in Turulung Vii. 2013 was a year with higher average temperatures than the annual average in Baia Mare and Turulung Vii, but lower in Ažimleul Silvaniei, but the precipitations were lower in the same areas, compared to the multiannual average. The higher amount of sugar was accumulated in E»FeteascAƒ albAƒE¼ in Ažimleul Silvaniei and the lowest in E»FeteascAƒ regalAƒE¼ in Baia Mare, the acidity falling between a normal interval for wine varieties.
