Characterization of the Origin Denomination “Ribeira Sacra”

Abstract

“Ribeira Sacra” is an origin denomination located between the provinces of Lugo and Ourense, in Galicia (northwest of Spain). With a surface of 1.250 Ha, the Ribeira Sacra is divided into 5 different subzones where the main culture variety is the Mencía cultivar. The evaluation of the ground fertility index and its repercussion in the wine quality of the 5 subzones was determined in 2003. The ground analyses indicated that all the parcels are sandy textured with high C/N ratio. Most of the samples showed an average value of acidity, with unbalance in the phosphorus and potassium content. Important differences were detected in the alcoholic levels, total acidity and pH of wines. The malic acid content varied according to the location. Important differences in the anthocyanin concentration and the total polyphenol index were found.

Antioxidant activity of grape seed and skin extract during ripening

Reactive oxygen species (ROS) play an important physiological role in the body’s defense and being involved in numerous signaling pathways 1, 2. When the balance between oxidant and antioxidant species is altered in favor of ROS, oxidative stress is generated. In this condition the cells are damaged as the ROS oxidize important cellular components, such as proteins, lipids, nucleic acids and
