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.

Occurrence of methyl salicylate in lugana wines: aroma impact and biogenesis 

AIM Methyl salicylate (MeSA) has been reported as a potentially impactful compound in Verdicchio wines produced in central Italy. Lugana is another white wine produced in the north-east of Italy from a grape locally known as Trebbiano di Soave, sharing a very similar genetic background with Verdicchio. The aims of this study were evaluating MeSA occurrence in Lugana, assessing its aroma impact on white wines aroma and elucidating its biogenesis during vinification. METHODS Fifteen Lugana wines were analysed for methyl salycilate content in comparison with Verdicchio, Pinot grigio and Garganega wines. MeSA impact on white wine aroma was studied by means of triangular test, adding MeSA at different concentrations. Possible routes of MeSA formation by yeast were investigated by means of a high throughput assay in which S. cerevisiae cells were put in contact with precursor such as salicylic acid (esterification) or glycosidic extracts (glycosidase). Sub-fractions of Lugana glycosidic extracts were also obtained by HPLC fractionation, allowing further evaluation of precursors role.
