ABSTRACT
Researches were carried out in 2015 in three most important vineyards from western of Romania - Minis, Recas and Buzias on different soil types: red-brown in Recas, rendzina in Minis, chernozem soil in Buzias. It was measured separately for varieties and crop areas, sugar and acidity in grape juice, physico-chemical and organoleptic properties of wine (alcohol content, total acidity and volatile anthocyanins content, colour, clarity and wine body). Research has focused mainly on the strong influence of soil type on grapes composition and wine quality from several red wine varieties: Feteasca Neagra, Cadarca, Cabernet Sauvignon, Merlot and Pinot noir.
Results obtained showed major differences between growing areas, mainly due to different soil types. Cadarca and Merlot varieties gave the best results in Minis, while Cabernet and Pinot noir were excellent in Recas.
Soil type in correlation with appropriate cultivation technologies, climatic factors and winemaking techniques and practices, decisively influence the typicity and quality of wines. All these factors are embodied in the concept of terroir - an important factor in viticulture and winemaking.
There aren’t reliable proves about links between soil mineral composition and fragrance or flavour of the wines, but these compounds synthesized in the vine derived from photosynthesis and from mineral ions taken up from the soil. The physical properties of the soils, through the water supply to the vine, determine wine quality. As results of the research shows, locations with a similar climate but different geology and soils produced similar or very different quality wines with flavours and aromas typical for that variety.
