Sebastijan Štemberger was born into a winemaking family in the Vipava valley. They moved to Karst in 2011 and took over the management of the property, renowned for the oldest Teran grapevine on Karst, a 250-years-old grapevine named Teranovka. It is said that the first grapevines of the whole of Kras, were planted at this estate.
Certified organic since 2010 and biodynamic for the last 5 years Sebastijan has a very studious and analytical approach to winemaking that does not allow for mistakes. He has studied biodynamic principals in Italy and Switzerland. With all of his studious work, he has managed to transform the yield of the Vitovska wine grape to make them smaller and get a better ratio of pulp to skin. All together the Sebastijan operates with about 20 acres of vineyards the majority of which is situated in the Karst plateau and the rest in the Vipava Valey in a good year he makes 24.000 bottles which seems like a lot but in comparison with other winemakers in the world is nothing.
His roots are in the area but he has always had an eye open to practices abroad and since first coming across concrete eggs in Piedmont in 2005 he has been experimenting with them ever since they are the perfect vessel for maceration as it acts a closed space which minimises oxidation and keeps the fruitiness and varietal differences of each type of grape.
Robinia is the white cuvée of Sebastjan and is a mix of wines from the Karst Plateau as well as the Vipava Valey. It has 40% of Rebula or Ribolla, 40% of Laški Rizling or Welshriesling, and 20% of Malvasia.
The Riesling and Malvasia were macerated for 7-10 days in open vats and then decanted for 12 months in conical wooden vats called Tino. Then the Ribolla was added and everything was aged for 36 months in oak barrels.
