At a vertical tasting going back to 1997 hosted by the Hong Kong Wine Society, participants discovered not only the tremendous quality potential of this legendary wine but also how beautifully the grapes of Sardinia can age.  The 12 wines tasted impressed most by how consistent their quality was throughout, especially since each vintage showed apparent stylistic differences.  This last discovery was another finding we did not expect and we removed from our minds the long-lasting belief that Italian vintages do not mark wines as much as they do in more northern wine regions of Europe. We learned this lesson with wines from a Mediterranean island even more surprising. Overall, the wines showed a delightful freshness of acidity with exquisite balance and proportion.  Each vintage intriguingly expressed a different personality and was equally enjoyed by all.
