Claus Preisinger has honed his skills around the world, working in vineyards in California, before returning to his Austrian roots to work for Anita and Hans Nittnaus. After branching out on his own, he has kept the respectful and honest winemaking he learned there, and is applying it a stone's throw away in the town of Gols. His "Kieselstein" Zweigelt is one of the most immediately enjoyable wines that I have had the opportunity to drink as of late. This beautifully pure Zweigelt was fermented in neutral barrels with a touch of sulphur added at bottling. Claus Preisinger has been using ambient yeasts since 2002 as well as little to no sulfites. The Preisinger wines are certified biodynamic, which Claus takes very seriously. His commitment to the environment and non-interventional winemaking shines through in the superior wines he produces.  Super fresh and juicy. Can be served chilled.
