It is produced only in exceptional wine-growing years when the weather conditions allow the grapes to fully ripen. Harvesting is done by hand with strict selection in the vineyard and another selection of grapes in the cellar. Fermentation takes place on our own yeasts with longer maceration with the aim of extracting as much quality ingredients from the skin as possible. After fermentation, the wine is aged on the lees from its own yeasts for 18 to 24 months.
