Volcanic soils composition impact on the major mineral elements content of grapes and wines

Abstract

The analysis of potassium, sodium, calcium and magnesium was carried out in soils, grapes and wines of wine regions of the Azores in order to obtain a mineral profile of the principal major elements. It would be of interest to achieve a profile of these minerals, according to the climate, to the position of the Islands and to their volcanic soils. Determinations were carried out by atomic absorption in flame. A statistical analysis of the findings was performed. This study establishes the diversity of wine regions in the Azores. As a whole, the amounts in the wines are in the european average.
