Abstract
The aim of this work was focused on the study of the influence of grape variety and aging time in contact with lees and without lees, on volatile composition and foamability of white and rosé sparkling wines. Seven different grape varieties were used and the sparkling wines were studied until 30 months of aging on lees and after 12 months of aging in bottle after disgorging.Sparkling wines from Albarín, Verdejo, Godello and Prieto Picudo grape varieties were the richest in most of the volatile compounds analyzed, especially those that contribute to the fruity aroma of wines, and maintained their varietal characteristics even after long aging time (30 months). Verdejo and Prieto Picudo sparkling wines presented the best foam characteristics, followed by Albarín and Godello wines.Considering all the results, Albarín, Verdejo, Godello and Prieto Picudo were the most interesting grape varieties to elaborate sparkling wines, following the traditional or “champenoise” method.
