The main variety for red wines is Blauer Zweigelt, which also found home in the soils of Langenlois. For the Zweigelt Reserve, the Rosner family always chooses the oldest Zweigelt vineyards to select from. Every year, the grapes are cut in half to reach a good ripeness in the cool-climate conditions in Kamptal/Austria.
For the Zweigelt Reserve Norbert and Stefan always want ripe and juicy grapes from old vines. After fermenting as whole berries on skins and some gentle pump-overs, the mash is pressed and racked into old wooden barrels, where the wine can finish fermenting and rest for another year before bottling.
