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.

Stockkultur is a 0.3-hectare plot at the top of Achleiten and was purchased by Toni Bodenstein in 2005. The name refers to the old style of training each vine to a single stake; the traditional method of vine cultivation in the Wachau before the 1950s. The vines planted in 1938 are among the oldest in the Wachau.
