Riesling grapes produce both refreshing light-bodied wines and full-bodied table wines to pair with the greatest cuisine. Riesling has a very high natural acidity, which both balances the sugar in sweeter wines and acts as a preservative for long aging. The oldest, still-living wine ever tasted was not red–it was a German Riesling from the 1540 vintage. It was tasted in 1961, after 420 years, and had not yet perished.
