Founded in 1986 by Delia Viader, VIADER was recognized early on as a first growth property and the wines have been highly coveted since inception.

VIADER Vineyards & Winery is located 1200 feet above the Napa Valley floor just northeast of St. Helena on the steep, rocky slopes of Howell Mountain. Born in Argentina, proprietor Delia Viader spent much of her formative years in Europe and especially in France. Delia came to the United States as a post-graduate student and earned her PhD. While raising four children on her own, Delia forged the vision and design for this unique estate vineyard property, and the handcrafted small production red blends and varietal wines.

Emulating a planting design quite rare in California, the vines are oriented up and down the steep hillsides, a planting method that optimizes sun exposure, vine density and erosion control. Planting on such a steep grade of 32 % is a challenge and requires meticulous hand farming. Delia has earned the reputation as a pioneer for planting the vines in a style normally found in Bordeaux. Delia's vineyards on Howell Mountain were regarded as an ideal model for growing super-premium quality grapes.

Today Viader Vineyards is a thriving family business producing world-class wines from a magnificent, mature estate vineyard property complete with small bonded winery, underground caves, and a Hospitality Center which offers tours and tastings by appointment and a sophisticated wine and food pairing Culinary Program.
