Smaragd is a designation of ripeness for dry wines used exclusively by members of the Vinea Wachau. The wines must have minimum alcohol of 12.5%. The grapes are hand-harvested, typically in October and November, and are sent directly to press where they spontaneously ferment in stainless-steel tanks.

Ried Achleiten sits east of Weiβenkirchen and is one of the most famous vineyards in the Wachau. The steeply-terraced vineyard has existed since Roman times. Some sections have just 40 cm of topsoil over the bedrock of Gföler Gneiss, amphibolitic stone, and slate, or “destroyed soil,” as Toni Bodenstein prefers to say.
