Smaragd is the Wachau designation for dry late harvest wines, above 12.5% alcohol through natural fermentation.  The best smaragd wines can age well for decades. Documented as early as 1050, the site in Wösendorf, at the foot of the Hochrain, is influenced by the sediment and stone soils of its highly situated vineyards, producing wines with a dense mineral texture and fine fruity flavors.
