Influence of the growing region, quality classification and harvest year on the ORAC (Oxygen Radical Absorbance Capacity) index of Chilean Cabernet Sauvignon red wines
In the present work, we studied the effect of the growing region (IV, Metropolitan or VI - VII regions), quality classification ("Varietal", "Reserva", and "Gran Reserva") and harvest year (2000-2012) on the total phenolic content and antioxidant capacity of thirty-six...
