Weingut Bründlmayer is an Austrian wine producer located in Langenlois, Kamptal, approximately 43 miles (70 km) northwest of Vienna. The estate specializes in whites wines primarily from the Grüner Veltliner grape, as well as Riesling and Chardonnay. Since 1947, a selection of the estate's most valued wines have been stored in a 700-year-old cellar as a "vinothek" (wine collection) in order to provide a historical archive for future generations.

The estate has holdings across several largely terraced vineyards either side of the Kamp and Loisbach rivers. The famed Zöbinger Heiligenstein and neighboring Kammerner Lamm lie to the east of Langenlois on southwest-facing sandstone and lime-rich clay slopes on the eastern bank of the Kamp. Proprietor Willi Bründlmayer places great importance on the ecological balance of his vineyards and only uses organic fertilizers for the cultivation of his vines. He relies on natural resources: no herbicides are employed and the vines are trained just above ground level to maximize on the beneficial effects of the soil's heat on the grapes.
