Hareter is a 4th generation family estate producing certified organic wines from eastern Austria. The farm dates back to 1725, and is today managed by Thomas Hareter and his wife, Claudia. The winery began their conversion to organic viticulture, and became fully certified in 2006. The wines have at most trace amounts of sulfites (below 75 ppm), but in some cases not at all. The farm itself comprises 15 hectares of vineyard on the loamy gravel shores of Lake Neusiedl, near the Hungarian border about 50 km from Vienna.  Hareter makes his natural wines from the indigenous grapes of the region such as Zweigelt, Blaufränkisch, and St-Laurent, while also crafting exceptional wines from international varieties like Chardonnay. The soils of his vineyards are rich in gravel and mineral deposits left behind from the sea which once covered the area, to which Thomas attributes the cool, fresh character of his wines.
