About Us / Andesite Vineyard History: Andesite Vineyard occupies the heart of the old Robinson property at the 2000-foot level five miles up Spring Mountain road from St. Helena. The vineyard has a microclimate perfect for Bordeaux-style varieties and a soil rich with andesite volcanic rock that provides for excellent vine root structure and development. The vineyard has multiple sun exposures and occupies a mountain saddle through which flows a river of cool night air. This natural combination of soil, warm days and cool nights produces superior grapes, not measured by tons, but by the depth and quality of the wine.
