Claus Preisinger's winery is right outside the tiny town of Gols, on the northeast corner of the Neusiedlersee. He currently farms 19 hectares split between about 64 different plots. Biodynamic since 2008, Claus has embraced the methodology to consistently produce delicious, layered, composed wines, showcasing the unadulterated terroir of Burgenland and often showcasing autochthonous varieties. The name 'Kalkstein' is in reference to the shell limestone soils found in the vineyards where the Blaufränkisch grows. Average vine age is 30-years-old, grapes are hand-harvested, and spontaneously ferment in stainless tank followed by aging sur lie in used large wooden barrel for six months before being bottled with low amounts of sulfur.

True to form, his Blaufränkisch shows bright minerality and great texture through the layers of juicy plum, black raspberry, and savory herbs.
