Research on the influence of the pedoclimatic conditions from Dealu Bujorului, Cotnari and Iaşi vineyards on the physico-chemical characteristics of the Fetească Albă and Busuioacă de Bohotin wines

Abstract

This study pursues the influence of the pedoclimatic conditions on the physico-chemical characteristics of the wines obtained in “Vasile Adamachi” Research Station of Iasi.Fetească albă and Busuioacă de Bohotin wines were obtained by the same wine-making technologies and in the same year of production (2012 for Fetească albă wine and 2013 for Busuioacă de Bohotin wine). Therefore, it can be followed only the influence of the pedoclimatic conditions from the vineyards where the grapes were used for winemaking. The main parameters that will be followed to determine the physico-chemical composition of wines studied are: sulfur dioxide, volatile acidity, total acidity, density, concentration of alcohol, reducing sugars, total dry extract, nonreductive extract, phenolic compounds and chromatic characteristics. By analyzing these parameters it can be established the degree of influence that have the pedoclimatic conditions on typicity of the grape variety and on the quality of wines produced from them.
