Fred Loimer started working with his father Alfred in 1988 after completing his studies at Klosterneuburg with stints in Germany's Nahe and Walter Schug winery in California. Fred took full control of his family's estate in 1997 and purchased the cellar of the Haindorf Castle on the outskirts of Langenlois. He then constructed a hyper-modern black cube on top of the old cellar symbolizing his aesthetic for modern elegance. Fred began practicing biodynamics in 2006 and is a founding member of Respekt, a certifying body for biodynamic viticulture in Austria. His wines are among the very best examples of Grüner Veltliner and Riesling in the Kamptal. In 2002, he was named "Winemaker of the Year" by Austria's Falstaff wine magazine.

Weingut Loimer consists of 65 hectares farmed entirely by biodynamic principals. His estate near Langenlois in the Kamptal region includes several Erste Lage, which are vineyards classified as "premier cru" by the prestigious Traditionsweingüter. Grüner Veltliners from Spiegel and Käferberg, and Rieslings from Seeberg, Steinmassal, and Heiligenstein are identified as Erste Lage with the symbol 1ÖTW. Following the appellation structure of the Traditionsweingüter, "Ortswein" (village wines) highlight the character of Fred's home village Langenlois, while "Gebietswein" (regional wines) such as Lois Grüner Veltliner and Lenz Riesling, reflect the quality and value of the Danube Valley. Fred also leases vines in Gumpoldskirchen where he produces Pinot Noir, Traminer, and the local specialty, Zierfandler.
