Von Strasser Winery specializes in unique and single-vineyard wines, all grown within Napa Valleys tiny Diamond Mountain District appellation. Each wine reflects both the unique characteristics of its site (terroir), and Rudys unique vision and winemaking philosophy. In the winery, Rudy blends both tradition and innovation together. Old world techniques such as extended maceration, French oak aging, and aerative racking are used in combination with modern equipment such as temperature controlled fermenters, state-of-the-art hand sorting systems and gentle handling equipment. However the most important tool in the winemaking process remains Rudys palette: every decision is ultimately based on Rudys vision of helping each vineyard attain it potential of producing world-class wine. In the vineyard, Rudy uses what he calls sustainable farming techniques. These include planting special cover crops to naturally increase the soil fertility and decrease erosion, and special trellising and irrigation techniques to reduce the potential for disease. Through these management decisions, the need for chemicals in the vineyard has almost been eliminated.
