The Bründlmayer family owns 12 hectares right in the centre of the Zöbinger Heiligenstein. 10,5 hectares are planted with Riesling, the remainder for experimental purposes with Cabernet (mostly Cabernet Franc). About 20% of the vineyards are trained in the Lyra trellis system. The other Heiligenstein vines are raised by the traditional Guyot method with the berries hanging 50-60 centimeters above the ground. Thinning is done as required to restrict the average yield to 3500-4000 liters per hectare for this classic (Kamptal DAC) Version. Two Reserves from Heiligenstein (Lyra, Alte Reben) are used to be harvested later in the year.
