Andesite Vineyard is a personal hands-on project of the proprietors. Our goal is to produce the best wine possible from this incredible Spring Mountain District terroir. The wine making philosophy is to let the grapes express themselves.
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.
Andesite Mervignon is the only wine produced. It is a smooth blend of estate grown Merlot, Cabernet Sauvignon, and touch of Cabernet Franc. Annual production is limited to about 150 cases by both the growing practices used in our efforts to produce the best quality fruit and by the limited number of vines that we planted.
We harvest in selected half-ton lots because our varied micro growing conditions spread peak flavor development over time. This selection by taste is a crucial key to producing the finest wine. Separate vinification of each small lot in French oak provides the components of the final Mervignon blend.
